9 Best Free Email Marketing Software in 2026 (Tested and Compared)

Free email marketing software rarely means what you think it means.

Some tools cap how many contacts you can store. Others cap how many emails you can send, no matter how small your list is. Mix the two up and you will pick the wrong tool for how you actually plan to use it.

I spent a few weeks this year signing up for the free plan on nine different platforms to sort out exactly where each one draws its line. Not from old comparison charts. From the actual pricing pages, checked this year.

I recommend tools to clients constantly, and a stale number in a blog post is how you end up recommending something that changed three months ago.

If a welcome sequence or an abandoned cart email matters to you, that alone will decide half of this list for you. I have flagged exactly which free plans support it and which don’t.

Let’s get into it.

Free Email Marketing Software Comparison at a Glance

Before looking at each tool in detail, this comparison gives you a quick view of how the free plans differ. It highlights the key limits, strengths, and best use cases so you can narrow down the right option faster. 

Tool	Best For	Free Plan
Mailchimp	Brand recognition and integrations	250 contacts, 500 sends/month
Brevo	Big contact lists that send occasionally	100,000 contacts, 300 emails/day
Sender	Most generous free plan overall	2,500 subscribers, 15,000 emails/month
MailerLite	Design and editor experience	250 subscribers, 2,500 emails/month
GetResponse	Bundled landing pages and forms	500 contacts, 2,500 messages/month
Systeme.io	All-in-one funnels, courses, and email	2,000 contacts, unlimited emails
HubSpot	CRM-integrated small teams	Unlimited contacts, 2,000 sends/month
Zoho Campaigns	Teams already using Zoho	2,000 contacts, 6,000 emails/month
Omnisend	Ecommerce automation	250 contacts, 500 emails/month

What to Look For in Free Email Marketing Software

Free plan generosity. Look at both numbers: how many contacts you can store, and how many emails you can send. A platform can be generous on one and stingy on the other.

What’s actually included for free. Automation, landing pages, and A/B testing get gated behind paid plans more often than not. Check the free plan’s real feature list, not the homepage.

What happens when you outgrow it. Some tools bump you up gently, one small tier at a time. Others force a big jump the moment you cross the line. Know which one you are dealing with before you build your list on it.

Deliverability. A free tool that lands in spam is worse than paying for one that lands in the inbox. This is hard to verify from a pricing page, so we leaned on user reports and G2 and Capterra reviews for this one.

Ease of use. If you are running this yourself without a marketing team, the editor and the setup flow matter as much as the feature list.

Support on the free tier. A few platforms cut off live chat or email support the moment you are not paying. Worth knowing before you are stuck mid-campaign.

How I Selected and Scored These Tools

I started from a broader list of the platforms that consistently show up for this keyword, then narrowed it down to nine that cover the range of people actually searching for this: small businesses, startups, solo creators, nonprofits, and ecommerce sellers.

I built a weighted scoring model instead of ranking on gut feel. Here’s what I weighted, and why.

Criteria	Weight	Why it matters
Free plan generosity (contacts + sends)	25%	This is the entire point of the search, and it’s also the number vendors quietly shrink
Features included free (automation, landing pages, forms)	20%	Automation especially has been stripped from free tiers across the category in the last year
Ease of use / setup	15%	Most people searching this do not have a dedicated marketing team
Pricing predictability once you outgrow free	15%	A free plan that vanishes overnight and forces a steep upgrade is a real risk in this category right now
Deliverability	10%	A free tool is no bargain if your emails land in spam
Support on the free tier	10%	Several platforms restrict support access to paid users only
Review sentiment (G2, Capterra, Trustpilot)	5%	A sanity check against real user experience, weighted lower since it’s directional rather than decisive

A note on that last row: review platforms don’t always agree with each other. Mailchimp, for example, scores solidly on G2 but noticeably worse on Trustpilot, where a lot of the recent reviews are reacting to this year’s pricing changes. I’ve flagged that kind of gap where it shows up.

The 9 Best Free Email Marketing Software, Reviewed

Free plans can look similar on paper, but the differences become clear once you start using them. 

We reviewed nine email marketing tools to find which ones offer the best value, features, and room to grow without a paid subscription. 

1. Mailchimp – Best for Brand Recognition and Integrations

Best for: Beginners who want the most widely recognized name and the biggest integration library
Starting price: Free, paid plans from $13/month
Key differentiator: 300+ integrations, but the smallest free plan on this list

Mailchimp is still the first name many people think of when they look for email marketing software. It has been around for years and built a reputation around simplicity, templates, and a huge integration ecosystem. The platform connects with hundreds of tools, including ecommerce platforms, CRMs, websites, and analytics tools.

That familiarity is the biggest reason many beginners start with Mailchimp. The free plan gives you the core email-building experience, basic reporting, signup forms, and audience management tools. It is enough to send newsletters and test the platform before committing to a paid plan.

The problem is that Mailchimp’s free tier is much smaller than it used to be. With only 250 contacts and 500 monthly sends, growing businesses can hit the limit quickly. Automation features, which are a major reason people use email marketing platforms, are now locked behind paid plans.

Mailchimp works best if you value brand recognition, integrations, and an easy learning curve more than getting the most features for free. If you are building a small newsletter or already use tools that connect with Mailchimp, it remains a reliable option. If you want maximum free-plan value, other platforms on this list offer more room to grow.

What Features Does Mailchimp Include on the Free Plan?

• Email builder: Drag-and-drop editor for creating newsletters without coding.
• Templates: Access to pre-designed email templates for campaigns and announcements.
• Audience management: Store contacts, organize audiences, and manage subscriber data.
• Signup forms: Create basic forms to collect new subscribers.
• Reporting: Track basic email performance metrics like opens and clicks.
• Integrations: Connect with hundreds of third-party tools, including ecommerce platforms and CRMs.
• Automation: Limited on the free plan, with advanced workflows requiring a paid subscription.

What Are the Pros of Mailchimp?

• Beginner-friendly editor; lets new users create emails quickly without needing design or coding skills.
• Large integration library; connects with ecommerce platforms, websites, CRMs, and analytics tools.
• Strong brand recognition; many businesses trust it because it has been established in the email marketing space for years.
• Wide range of templates; makes it easier to create newsletters, promotions, and announcements.
• Helpful learning resources; provides guides, tutorials, and documentation for users getting started.

What Are the Cons of Mailchimp?

• Limited free allowance; the plan supports only 250 contacts and 500 monthly sends, which many growing businesses can outgrow quickly.
• Automation is locked behind paid plans; features like welcome sequences and abandoned cart emails are unavailable for free users.
• Pricing increases as your list grows; scaling can become more expensive than several alternatives.
• Audience structure can increase costs; duplicate contacts across different audiences may count separately.
• Free support is limited; paying customers receive better access to support options.

How Much Does Mailchimp Cost?

The Free plan covers 250 contacts and 500 sends a month, with a daily cap of 250 sends. Email support lasts only your first 30 days.

Essentials starts at $13/month for 500 contacts. Standard starts at $20/month and adds advanced automation. Premium starts at $350/month for 10,000 contacts.

The catch is how contacts are counted. You pay for everyone on your list, including unsubscribed contacts, unless you archive them yourself.

Mailchimp also raised prices in April 2026 for legacy accounts created before May 2019. Check the live calculator for your exact tier.

What Do Reviews Say About Mailchimp?

• G2: 4.3/5 (12,987+ reviews)
• Capterra: 4.5/5 (17,681+ reviews)

Skip Mailchimp if: you need automation on a free plan, or you are starting with more than 250 contacts already. Either one will have you upgrading in week one.

Verdict: Mailchimp is a fine choice if brand recognition and integrations matter more to you than free-plan value, and you’re ready to pay fairly quickly. If you’re trying to stay free as long as possible, it is no longer the strongest option in this list.

2. Brevo – Best Free Plan for Large Contact Lists

Best for: Businesses with a big list who don’t email every day
Starting price: Free, paid plans from $9/month
Key differentiator: Prices by emails sent, not contacts stored, and lets you store up to 100,000 contacts free

Brevo takes a different approach from most email marketing platforms. Instead of limiting how many contacts you can store, it focuses on how many emails you can send each day. That makes it a strong option for businesses with large lists that do not send campaigns every day.

The platform combines email marketing with other tools like SMS campaigns, basic CRM features, signup forms, and marketing automation. Its free plan allows up to 100,000 stored contacts, which is far higher than most competitors. You also get access to features like segmentation and automation, although some limits apply.

This makes Brevo especially useful for businesses that have built a large audience but only need occasional newsletters or updates. A nonprofit, community, or company with an older subscriber database can store contacts without immediately paying more.

The tradeoff is the daily sending limit. If you regularly send campaigns to thousands of subscribers, the 300 emails per day cap can become restrictive. Brevo works best when your priority is keeping a large contact database at a low cost, rather than sending high-volume campaigns every day.

What Features Does Brevo Include on the Free Plan?

• Email campaigns: Create and send newsletters using a drag-and-drop email editor.
• Email templates: Access pre-designed templates for different campaign types.
• Contact management: Store up to 100,000 contacts without paying for list size.
• Segmentation: Group contacts based on customer data and campaign behavior.
• Marketing automation: Build basic automated workflows for up to 2,000 contacts.
• Signup forms: Create forms to collect new subscribers and grow your list.
• CRM tools: Includes a basic CRM system for managing customer relationships.
• SMS marketing: Supports SMS campaigns as part of Brevo’s broader marketing platform.
• Reporting and analytics: Track campaign performance through basic open and click reports.
• Daily sending limit: Free users can send up to 300 emails per day, which is the main restriction of the plan.

What Are the Pros of Brevo?

• Generous contact allowance; lets businesses store up to 100,000 contacts without paying based on list size.
• Flexible pricing model; works well for companies with large audiences that send emails less frequently.
• Built-in automation tools; includes basic workflows that many free plans restrict to paid users.
• Includes CRM features; helps manage customer information alongside email campaigns.
• Supports multiple channels; combines email marketing with SMS and other communication tools.

What Are the Cons of Brevo?

• Daily sending cap can be limiting; the 300 emails per day restriction may not work for frequent campaigns.
• Free emails include branding; users need a paid plan to remove Brevo logos and branding.
• Landing page features are restricted; advanced lead generation tools require an upgrade.
• Automation limits apply; larger audiences need paid plans to access more advanced workflows.
• Free support is limited; faster assistance and priority support are mainly available for paying customers.

How Much Does Brevo Cost?

The Free plan stores up to 100,000 contacts and sends 300 emails a day. Brevo branding appears on every email.

Paid plans are priced by monthly email volume. Starter runs $9 for 5,000 emails, $19 for 20,000, and $69 for 100,000. Removing branding on Starter costs about $10.80/month extra.

Standard starts at $18/month, removes branding, and adds landing pages. Professional starts at $499/month. Annual billing saves 10%.

One catch: since October 2025, the cheapest Starter and Standard tiers cap stored contacts at 500, 1,500, or 2,500. A bigger list can force a higher tier than your sending needs.

What Do Reviews Say About Brevo?

• G2: 4.5/5 (2,634+ reviews)
• Capterra: 4.6/5 (3,517+ reviews)

Skip Brevo if: you send campaigns daily to a list over a few thousand people. The daily send cap will bite fast, and you’re better off with a contact-based free plan instead.

Verdict: Brevo is the strongest pick here if your list is bigger than your sending frequency. The pricing model genuinely works in your favor if you’re not a daily sender.

3. Sender – Most Generous Free Plan Overall

Best for: Anyone who wants the most room to grow before paying anything
Starting price: Free, paid plans from $10/month
Key differentiator: Full feature parity between free and paid, just with branding attached

Sender is one of the lesser-known names in email marketing, but its free plan offers some of the strongest limits in this category. While platforms like Mailchimp focus on brand recognition, Sender focuses on giving users more room before they need to upgrade.

The free plan supports up to 2,500 subscribers and 15,000 emails per month. You also get access to key features like email automation, segmentation, popups, analytics, and the drag-and-drop email builder. Unlike some competitors, Sender does not lock away major features just to push users toward a paid plan.

This makes it a strong choice for small businesses, creators, and growing newsletters that want a platform they can stay with for longer. You can build welcome sequences, collect leads, and manage campaigns without immediately running into tight limits.

The downside is that Sender is not as advanced as larger platforms when it comes to reporting and deeper marketing analytics. It also lacks the massive integration ecosystem that tools like Mailchimp have built over the years.

If your main goal is getting the most useful email marketing features without paying, Sender is one of the best starting points. It gives you enough space to grow while keeping the experience simple for beginners.

What Features Does Sender Include on the Free Plan?

• Email builder: Create newsletters and campaigns using a drag-and-drop editor designed for beginners.
• Email automation: Build automated workflows such as welcome emails and subscriber follow-ups.
• Subscriber management: Store up to 2,500 subscribers on the free plan.
• Email sending: Send up to 15,000 emails per month without a paid subscription.
• Segmentation: Organize subscribers into groups based on audience data and behavior.
• Signup forms and popups: Capture leads through embedded forms and website popups.
• Analytics: Track basic campaign performance, including opens, clicks, and subscriber activity.
• Templates: Use pre-built email designs to create campaigns faster.
• Landing pages: Create simple pages to collect leads and grow your email list.
• Free-plan access: Most core features are available without upgrading, with paid plans mainly adding higher limits and removing branding.

What Are the Pros of Sender?

• Strong free plan limits; supports up to 2,500 subscribers and 15,000 emails per month without a paid subscription.
• Most features are available upfront; users get automation, segmentation, analytics, and forms without major restrictions.
• Good automation options; makes it possible to create welcome emails and follow-up sequences on the free tier.
• Simple campaign builder; the drag-and-drop editor is easy for beginners to learn.
• Useful lead capture tools; includes popups and signup forms to help grow an email list.

What Are the Cons of Sender?

• Basic reporting capabilities; analytics may feel limited for businesses that need deeper campaign insights.
• Smaller integration ecosystem; it does not connect with as many third-party tools as larger platforms like Mailchimp.
• Branding remains on free emails; removing Sender branding requires upgrading.
• Limited advanced marketing features; larger teams may need more powerful segmentation and reporting tools.
• Lower brand recognition; fewer businesses are familiar with Sender compared with established competitors.

How Much Does Sender Cost?

The Free Forever plan covers 2,500 subscribers and 15,000 emails a month. You get one user seat, and Sender branding stays in the footer.

Standard costs $10/month for 1,000 subscribers and 12,000 emails. It rises to $57/month at 10,000 subscribers and removes branding.

Professional costs $14/month for 1,000 subscribers with double the sends. It rises to $120/month at 10,000.

Pay As You Go credits suit rare senders but cost far more per email.

What Do Reviews Say About Sender?

• G2: 4.7/5 (279+ reviews)
• Capterra: 4.7/5 (212+ reviews)

Skip Sender if: you need deep analytics or conversion tracking. The free plan’s reporting will feel thin once you’re past basic open and click rates.

Verdict: If your main goal is stretching a free plan as far as possible before paying anything, Sender is hard to beat on the numbers alone.

4. MailerLite – Best Design and Editor Experience

Best for: Creators and small businesses who care about how the final email looks
Starting price: Free, paid plans from $12/month
Key differentiator: The cleanest editor in this category, even after a significant free-plan cut

MailerLite has built its reputation around making email marketing feel simple. It is designed for creators, small businesses, and teams that want professional-looking emails without spending hours learning complex software.

The platform stands out because of its clean editor, modern templates, and beginner-friendly workflow. Even users with no design experience can create newsletters, landing pages, signup forms, and automated campaigns with minimal setup. The free plan includes essential tools like email campaigns, basic automation, forms, and a website builder.

MailerLite is especially popular among bloggers, newsletters, and small brands that care about presentation. Its drag-and-drop builder gives you more control over layouts and content blocks compared with many free alternatives. The interface feels less crowded, which makes everyday campaign management easier.

The main limitation is the smaller free plan compared with competitors like Sender and Brevo. With 250 subscribers and 2,500 monthly emails, growing audiences can reach the limit quickly. Some advanced templates, reporting features, and automation capabilities are also reserved for paid users.

MailerLite is a strong choice if you value simplicity and design quality over having the largest free allowance. It gives you a polished email marketing experience, but you should expect to upgrade once your audience starts growing.

What Features Does MailerLite Include on the Free Plan?

• Email builder: Create newsletters with a clean drag-and-drop editor and customizable content blocks.
• Email campaigns: Design and send regular newsletters, promotional emails, and updates.
• Automation: Create basic automated workflows, including welcome sequences and subscriber follow-ups.
• Signup forms: Build embedded forms, popups, and landing pages to collect subscribers.
• Landing pages: Create simple lead-generation pages without needing a separate website tool.
• Website builder: Build basic websites alongside your email marketing campaigns.
• Templates: Access ready-made email designs and layouts for faster campaign creation.
• Subscriber management: Store and organize contacts based on subscriber information and engagement.
• Custom HTML editor: Add custom code to emails for more design flexibility.
• Free-plan limits: The free tier supports up to 250 subscribers and 2,500 monthly email sends, with advanced features available on paid plans.

What Are the Pros of MailerLite?

• Clean and intuitive interface; makes email creation simple for beginners and small teams.
• Strong design tools; the editor provides polished templates and flexible content blocks for attractive campaigns.
• Useful free features; includes forms, landing pages, website tools, and basic automation without payment.
• Good balance of simplicity and functionality; avoids the complexity found in larger marketing platforms.
• Helpful customer support reputation; users often highlight quick and friendly assistance.

What Are the Cons of MailerLite?

• Smaller free plan limits; the 250-subscriber and 2,500-email allowance can become restrictive as lists grow.
• Advanced features require payment; more complex automation, reporting, and testing options are limited.
• Template access is restricted; some premium designs are only available on paid plans.
• Fewer integrations than larger platforms; businesses using many external tools may find fewer connection options.
• Pricing increases after growth; larger subscriber lists require moving into higher paid tiers.

How Much Does MailerLite Cost?

The Free plan covers 250 subscribers and 2,500 emails a month. It also caps you at 3 active automations, 3 forms, and 1 landing page, with branding on.

MailerLite cut this from 500 subscribers and 12,000 emails in June 2026. Paid plans were renamed and repriced at the same time.

Comfort starts at $12/month for 500 subscribers and $19/month at 1,000. Sends are capped at 10x your list size.

Power starts at $25/month for 500 subscribers and $39/month at 1,000. It removes the usage caps.

Prices rose 10% to 30% across tiers. Annual billing saves 10%, and nonprofits get 30% off.

What Do Reviews Say About MailerLite?

• G2: 4.6/5 (1,113+ reviews)
• Capterra: 4.7/5 (2,322+ reviews)

Skip MailerLite if: you’re starting with more than 250 contacts, or you need the free plan to last you more than a couple of months. Budget for Comfort at $12/month sooner rather than later.

Verdict: MailerLite still makes the nicest-looking emails in this list with the least effort. Just go in knowing the free plan is now a trial runway, not a long-term home.

5. GetResponse – Best for Bundled Landing Pages and Forms

Best for: Solo founders who want a landing page along with their email tool, for free
Starting price: Free, paid plans from $19/month
Key differentiator: The only free plan here that includes a real landing page builder

GetResponse is more than just an email marketing platform. It combines email campaigns with landing pages, signup forms, automation tools, webinars, and other marketing features. This makes it appealing for solo founders and small businesses that want multiple marketing tools in one place.

The free plan gives users access to the core email builder, templates, forms, and a landing page builder. That landing page feature is where GetResponse stands out, as many competitors reserve similar tools for paid plans. You can create a simple lead capture system without needing another website tool.

It works well for businesses that are building an email list from scratch. A creator can launch a newsletter, collect subscribers through forms, and send campaigns from the same dashboard. The interface also keeps the experience consistent when moving from free features to paid plans.

The limitations appear when you need deeper automation. Advanced workflows, A/B testing, and more powerful marketing features require a paid subscription. The 500-contact limit can also feel restrictive once your audience starts growing.

GetResponse is a good fit if you want more than email sending alone. It is not the most generous free plan, but the combination of email tools and landing page features makes it useful for businesses building their first marketing funnel.

What Features Does GetResponse Include on the Free Plan?

• Email builder: Create newsletters and campaigns using a drag-and-drop editor with customizable layouts.
• Email templates: Access a large library of pre-designed templates for different campaign types.
• Landing pages: Build lead-generation pages directly inside GetResponse without using another tool.
• Signup forms: Create forms to collect email subscribers from websites and landing pages.
• Marketing automation: Set up basic automated emails, although advanced workflows require a paid plan.
• Contact management: Store and organize up to 500 contacts on the free plan.
• Reporting: Monitor basic campaign performance through email statistics and engagement data.
• Website builder: Create a simple website alongside email campaigns.
• Autoresponders: Send scheduled follow-up emails based on subscriber actions or timing.
• Free-plan limits: The free tier includes 2,500 monthly email sends, but features like A/B testing and advanced automation are restricted to paid plans.

What Are the Pros of GetResponse?

• All-in-one marketing toolkit; combines email marketing, landing pages, forms, websites, and other business tools in one platform.
• Built-in landing page builder; helps users collect leads without needing a separate landing page service.
• Large template library; provides many ready-made designs for emails and marketing pages.
• Beginner-friendly setup; the interface makes it easy to launch campaigns without technical experience.
• Smooth upgrade path; users can move from the free plan to paid features without switching platforms.

What Are the Cons of GetResponse?

• Limited free plan capacity; the 500-contact limit can become restrictive for growing lists.
• Advanced automation is paid-only; deeper workflows and customer journeys require an upgrade.
• No free A/B testing; testing and optimization features are reserved for paid users.
• Multiple lists can increase costs; duplicate contacts across lists may affect your plan limits.
• Less focused email experience; users who only need newsletters may find dedicated tools more suitable.

How Much Does GetResponse Cost?

The Free plan covers 500 contacts and 2,500 messages a month. It includes a landing page builder and signup forms, but GetResponse branding stays on your emails.

All paid plans include unlimited sends. Starter costs $19/month for 1,000 contacts, or about $15.58/month billed annually. It’s $29/month at 2,500 contacts and $79/month at 10,000. It includes just one automation workflow.

Marketer starts at $59/month and unlocks unlimited workflows. Creator starts at $69/month and adds webinars and courses. Nonprofits get 50% off.

Plan names vary across sources right now, so match them to GetResponse’s live pricing page.

What Do Reviews Say About GetResponse?

• G2: 4.3/5 (1,141+ reviews)
• Capterra: 4.2/5 (525+ reviews)

Skip GetResponse if: you manage the same contacts across multiple lists, or you need real behavioral automation on a free plan. Neither works cleanly here.

Verdict: If a landing page matters as much to you as the email tool itself, GetResponse’s free plan is the only one on this list that genuinely delivers both.

6. Systeme.io – Best All-in-One for Funnels, Courses, and Email

Best for: Solopreneurs who want funnels, courses, and email in a single free login
Starting price: Free, paid plans from $17/month
Key differentiator: Unlimited email sends on the free plan, which almost nothing else here offers

Systeme.io takes a different approach from traditional email marketing tools. It is built as an all-in-one business platform that combines email marketing, sales funnels, online courses, websites, and affiliate management in one dashboard. Email is one part of a larger system designed for creators and online businesses.

The free plan is where Systeme.io becomes interesting. You get unlimited email sends, up to 2,000 contacts, sales funnels, a course platform, and basic automation features without paying a monthly fee. For someone selling digital products or building an online business, this removes the need to connect several separate tools.

The platform works especially well for creators, coaches, and solopreneurs who need more than newsletters. You can collect leads, move them through a funnel, deliver a course, and manage customer relationships from the same account. That bundled approach is the main reason people choose Systeme.io over dedicated email tools.

The tradeoff is that the email experience itself is not as polished as specialized platforms like MailerLite or Sender. Automation options are limited on the free plan, and the templates and design tools are more focused on function than visual flexibility.

Systeme.io is a strong choice if email marketing is only one part of your business workflow. If you only need to send newsletters, dedicated email platforms may offer a smoother experience, but for an all-in-one setup, the free plan offers impressive value.

What Features Does Systeme.io Include on the Free Plan?

• Email campaigns: Create and send unlimited emails to contacts on the free plan.
• Email automation: Build basic automated workflows using triggers, rules, and subscriber actions.
• Contact management: Store up to 2,000 contacts and organize them using tags and segmentation.
• Sales funnels: Create up to 3 sales funnels for lead generation, product sales, or customer journeys.
• Landing pages: Build landing pages for collecting leads or promoting offers without external tools.
• Online courses: Create one course and host unlimited students directly inside the platform.
• Website and blog: Build a basic website or blog as part of the all-in-one platform.
• Segmentation: Use tags and audience groups to personalize email communication.
• File storage: Store digital files and assets needed for your funnels and courses.
• Free-plan limits: The free tier includes unlimited email sends, but automation rules, funnels, and other business features have usage limits before upgrading.

What Are the Pros of Systeme.io?

• Complete business toolkit; combines email marketing, sales funnels, courses, websites, and affiliate tools in one platform.
• Unlimited email sending; allows users to send emails without a monthly send limit on the free plan.
• Strong value for creators; removes the need to pay for separate funnel, course, and email tools.
• Generous free allowance; supports up to 2,000 contacts with useful features included.
• Built-in sales features; helps users collect leads, sell products, and manage customer journeys from one dashboard.

What Are the Cons of Systeme.io?

• Email features are not the main focus; dedicated email platforms offer more advanced campaign tools.
• Limited automation rules; the free plan restricts complex workflows and multiple sequences.
• Basic design options; templates and email layouts are less polished than tools focused only on email marketing.
• Fewer integrations; businesses using specialized software may find fewer connection options.
• Branding appears on free plans; removing platform branding requires upgrading.

How Much Does Systeme.io Cost?

The Free plan covers 2,000 contacts, 3 funnels, 1 course, and unlimited email sends. It’s capped at 1 automation rule, which is usually the first limit you hit.

Paid plans are flat-rate. Startup costs $17/month for 5,000 contacts, 10 automation rules, and no branding. Webinar costs $47/month for 10,000 contacts and adds evergreen webinars. Unlimited costs $97/month with no caps and free migration.

Annual billing gives you about two months free. There are no transaction fees on any plan.

Systeme.io’s pricing page lists an affiliate program on Free, though some reviews say it starts on Webinar.

What Do Reviews Say About Systeme.io?

• G2: 4.8/5 (750+ reviews) 
• Capterra: 4.8/5 (2,129+ reviews)

Skip Systeme.io if: you only need email, or you want more than one automation rule without paying. As a pure email tool, it’s outclassed by several others on this list.

Verdict: Systeme.io earns its spot for what it bundles, not for being the best standalone email tool. If funnels or a course are on your roadmap anyway, it’s genuinely hard to beat on price.

7. HubSpot – Best for CRM-Integrated Small Teams

Best for: Teams that want marketing and sales contacts living in the same free CRM
Starting price: Free, paid seats from roughly $15/month
Key differentiator: Unlimited free CRM contacts, tightly tied to sales tools most email-only platforms don’t offer

HubSpot approaches email marketing differently from most tools on this list. Instead of being only an email platform, it connects email campaigns with a full customer relationship management (CRM) system. This makes it useful for teams that want to manage marketing, sales, and customer data in one place.

The free plan gives you unlimited CRM contacts, email templates, forms, contact management, and basic reporting. You can track customer interactions, see email activity, and keep sales conversations connected with marketing efforts. For small teams already managing leads, this connection can be more valuable than having a larger email allowance.

HubSpot works best for businesses that need more than sending newsletters. A sales team can use the CRM to organize leads while marketing teams send updates and campaigns from the same system. The shared customer data creates a clearer picture of how people move from first interaction to purchase.

The biggest limitation is that the free email marketing features are restricted compared with dedicated email platforms. The 2,000 monthly email send limit can disappear quickly, and advanced automation, testing, and personalization require paid Marketing Hub plans.

HubSpot is a strong choice if CRM functionality matters as much as email marketing. If you only need newsletters and campaigns, tools like Sender or Brevo offer more email-focused value for free.

• Extensive ecosystem; connects with many HubSpot tools for sales, service, content, and operations.

What Are the Cons of HubSpot?

• Limited email sending on the free plan; the 2,000 monthly email limit can be restrictive for active campaigns.
• Email features feel secondary; dedicated email platforms provide more marketing-focused capabilities.
• Advanced automation requires payment; workflows, personalization, and testing tools are locked behind higher plans.
• Costs can increase quickly; paid Marketing Hub plans become expensive as teams and contacts grow.
• More complex for simple needs; small users who only need newsletters may find the platform unnecessarily large.

How Much Does HubSpot Cost?

HubSpot’s Free plan costs $0/month and includes basic marketing, CRM, sales, service, CMS, and commerce tools. It supports up to 2,000 marketing email sends per month but has limited automation and includes HubSpot branding.

Marketing Hub Starter starts at $7/seat/month when billed annually or $20/seat/month monthly. It includes 1,000 marketing contacts, email marketing, live chat, simple automation, CRM segmentation, and removes HubSpot branding.

Professional starts at $800/month with advanced automation, reporting, social media tools, and omnichannel marketing features, while Enterprise starts at $3,600/month with advanced attribution, customer journey analytics, and governance controls.

What Do Reviews Say About HubSpot?

• G2: 4.4/5 (14,979+ reviews)
• Capterra: 4.5/5 (4,484+ reviews)

Skip HubSpot if: email is your only need. You’ll be carrying a lot of CRM and sales infrastructure you won’t use, and dedicated email tools on this list do more for less.

Verdict: HubSpot’s free plan is less about email marketing and more about not needing a second tool for your CRM. If that’s genuinely useful to you, it’s worth the tradeoffs. If it isn’t, look elsewhere on this list first.

8. Zoho Campaigns – Best for Teams Already Using Zoho

Best for: Businesses already paying for Zoho CRM, Books, or other Zoho apps
Starting price: Free, paid plans from around $3/month
Key differentiator: Native, no-friction sync with the rest of the Zoho suite

Zoho Campaigns is an email marketing platform built around the wider Zoho ecosystem. It works especially well for businesses already using tools like Zoho CRM, Zoho Books, or other Zoho applications. The biggest advantage is how easily it connects customer data across different Zoho products.

The free plan includes email campaigns, signup forms, templates, basic segmentation, and autoresponders. You can manage up to 2,000 contacts and send up to 6,000 emails per month without paying. For small teams, this provides enough functionality to run regular newsletters and basic campaigns.

Where Zoho Campaigns stands out is its native connection with Zoho CRM. Instead of manually exporting contacts between platforms, businesses can keep customer information synced and use existing data for email campaigns. This makes it a practical choice for companies already invested in Zoho’s tools.

The downside is that the experience is less appealing if you are not using other Zoho products. The interface can feel less beginner-friendly compared with tools like MailerLite, and the template editor does not feel as polished. Some users also report a learning curve when setting up campaigns and workflows.

Zoho Campaigns makes the most sense for businesses that want an affordable email tool inside the Zoho ecosystem. If you are starting fresh and only need email marketing, other platforms on this list provide a smoother standalone experience.

What Features Does Zoho Campaigns Include on the Free Plan?

• Email campaigns: Create newsletters and promotional emails using Zoho’s campaign builder.
• Email templates: Use pre-designed templates for different types of marketing emails.
• Contact management: Store up to 2,000 contacts and organize subscriber information.
• Email sending: Send up to 6,000 emails per month on the free plan.
• Signup forms: Create forms and popups to collect new subscribers.
• Segmentation: Group contacts based on customer details and engagement data.
• Autoresponders: Set up basic automated email responses and follow-up messages.
• CRM integration: Connect with Zoho CRM and other Zoho applications to sync customer data.
• Campaign analytics: Monitor basic performance metrics such as opens and clicks.
• Free-plan limits: The free tier includes essential email marketing features, but more advanced automation, segmentation, and reporting capabilities require paid plans.

What Are the Pros of Zoho Campaigns?

• Strong Zoho integration; works smoothly with Zoho CRM and other Zoho applications for businesses already in the ecosystem.
• Affordable pricing structure; paid plans remain relatively low-cost compared with many competitors.
• Useful free limits; supports up to 2,000 contacts and 6,000 monthly emails without a subscription.
• Built-in campaign tools; includes templates, signup forms, segmentation, and basic automation features.
• Good fit for small teams; provides enough email marketing features without adding unnecessary complexity.

What Are the Cons of Zoho Campaigns?

• Best value depends on Zoho usage; businesses outside the Zoho ecosystem lose its biggest advantage.
• Less polished user experience; the interface feels less refined compared with tools like MailerLite or Brevo.
• Limited advanced features; deeper automation and reporting require paid plans.
• Smaller user community; there are fewer resources and discussions compared with larger platforms.
• Template editor has a learning curve; beginners may need more time to create campaigns.

How Much Does Zoho Campaigns Cost?

The Forever Free plan covers 2,000 contacts and 6,000 emails a month. You don’t need a credit card.

Paid plans are priced by contact count and include unlimited sends. Standard starts around $3 to $4/month for 500 contacts and reaches roughly $49/month at 10,000.

Professional starts around $4.50 to $5/month for 500 contacts and reaches about $70/month at 10,000. It adds advanced segmentation and ecommerce workflows.

Annual billing saves around 25%. A dedicated IP costs about $35/month extra.

Pricing varies by region and currency. Zoho’s own pricing page is the best source for your exact number.

What Do Reviews Say About Zoho Campaigns?

• G2: 4.3/5 (1,042+ reviews)
• Capterra: 4.3/5 (317+ reviews)

Skip Zoho Campaigns if: you’re not using any other Zoho product. The main advantage disappears, and other tools on this list offer a smoother standalone experience.

Verdict: This is a strong, low-cost pick specifically for existing Zoho users. For anyone else, it’s a fine tool but not a compelling reason to switch.

9. Omnisend – Best for Ecommerce Automation on a Free Plan

Best for: Shopify and WooCommerce sellers who want automation without paying upfront
Starting price: Free, paid plans from $16/month
Key differentiator: Full automation features, including abandoned cart flows, included free

Omnisend is an email marketing platform built specifically for ecommerce businesses. Unlike general email tools, it focuses on helping online stores turn visitors into customers through automated campaigns, product recommendations, and customer journeys.

The platform connects directly with ecommerce platforms like Shopify and WooCommerce, making it easier to use store data inside email campaigns. Its free plan includes features that many competitors lock behind paid tiers, including automation workflows, segmentation, landing pages, and abandoned cart recovery.

This makes Omnisend a strong choice for new online stores that want to test email marketing without a large upfront investment. A Shopify store owner can set up welcome emails, cart reminders, and basic customer follow-ups without paying from day one.

The main limitation is the sending volume. While the features are generous, the free plan only supports 500 emails per month, which can disappear quickly once you start running regular campaigns. It is also designed mainly for ecommerce, so service businesses and creators may not find many of the features relevant.

Omnisend works best for small online stores that want automation before they scale. If ecommerce is your main focus, it offers some of the most useful free features in this category. For general newsletters or non-store businesses, other platforms provide better flexibility.

What Features Does Omnisend Include on the Free Plan?

• Email campaigns: Create promotional emails, newsletters, and customer updates using a visual email builder.
• Ecommerce automation: Set up automated workflows such as welcome emails, abandoned cart reminders, and customer follow-ups.
• Shopify and WooCommerce integration: Connect online stores directly to sync products, customers, and purchase data.
• Segmentation: Group customers based on shopping behavior, purchase history, and engagement.
• Landing pages: Create simple pages to collect subscribers and promote products.
• Signup forms and popups: Capture new leads through website forms and promotional popups.
• Product recommendations: Use ecommerce data to personalize emails with relevant products.
• Analytics: Track campaign performance, clicks, and customer engagement.
• Automation templates: Access pre-built workflows designed for common ecommerce scenarios.
• Free-plan limits: The free tier includes automation features and ecommerce integrations but limits sending to 500 emails per month and up to 250 billable contacts.

What Are the Pros of Omnisend?

• Ecommerce-focused platform; built specifically for online stores that want to use email as a sales channel.
• Strong automation features; includes workflows like abandoned cart recovery and welcome sequences on the free plan.
• Native store integrations; connects easily with Shopify, WooCommerce, and other ecommerce platforms.
• Useful customer segmentation; lets businesses target shoppers based on purchases and behavior.
• Revenue-focused reporting; helps ecommerce brands understand how campaigns contribute to sales.

What Are the Cons of Omnisend?

• Low free sending limit; the 500 emails per month allowance can run out quickly for active stores.
• Limited use outside ecommerce; many features are designed around online store workflows.
• Costs increase with growth; larger contact lists and higher sending volumes require paid plans.
• Advanced reporting is restricted; deeper customer insights are available only on paid tiers.
• Smaller fit for general newsletters; creators and non-commerce businesses may find other platforms more suitable.

How Much Does Omnisend Cost?

The Free plan covers 500 emails a month to up to 250 contacts. You can upload more, but each campaign must go to 250 or fewer. Omnisend branding stays on.

Standard starts at $16/month for 500 contacts. Your monthly sends equal 12x your contact count. It runs roughly $132/month at 10,000 contacts.

Pro starts at $59/month and adds unlimited emails. It also includes SMS credits equal to your monthly bill.

Since May 4, 2026, new subscribers can only get SMS on Pro. Also watch your billable contacts. Abandoned-cart shoppers can push your tier up faster than you’d expect.

What Do Reviews Say About Omnisend?

• G2: 4.6/5 (1,244+ reviews)
• Capterra: 4.7/5 (836+ reviews)

Skip Omnisend if: you’re not running an ecommerce store, or your list is bigger than a few hundred active contacts already. The 500-email cap will not stretch far.

Verdict: For a new Shopify or WooCommerce store validating whether email automation is worth investing in, Omnisend’s free plan is the most purpose-built option on this list.

Contacts vs. Sends: Which Free Plan Model Actually Fits You

Before you pick a tool, it helps to know which of two models you’re dealing with.

Contact-capped tools (Mailchimp, MailerLite, GetResponse, Systeme.io, HubSpot, Zoho Campaigns, Omnisend) limit how many people you can store or message, sometimes alongside a separate send limit. These fit a small, growing list you plan to email regularly.

Send-capped tools (Brevo) limit how many emails go out, not how many contacts you store. These fit a larger list you email occasionally, like a quarterly update to a big audience.

If you send often to a small list, a generous send cap matters less than a generous contact cap. If you have a big list you rarely email, it’s the opposite. Sender is the rare case that’s generous on both numbers at once, which is a big part of why it ranks where it does below.

What Happens When You Outgrow the Free Plan

This is the part most comparisons skip, and it’s where a lot of the real cost of “free” software shows up.

Tool	First Paid Tier	What You Get at 2,500 Contacts (approx.)
Mailchimp	$13/month	~$45-50/month
Brevo	$9/month	Priced by sends, not contacts; often under $20/month at moderate volume
Sender	$10/month	~$15-20/month
MailerLite	$12/month	~$33/month
GetResponse	$19/month	~$29/month
Systeme.io	$17/month	$17/month flat up to 5,000 contacts
HubSpot	Seat-based	Varies significantly; check current tier pricing
Zoho Campaigns	~$3-4/month	Scales gradually, still among the cheapest here
Omnisend	$16/month	~$25-35/month depending on SMS usage

These are approximate figures based on published pricing at the time of writing. Contact-based pricing especially tends to shift, so treat this as a planning reference and confirm the current number before you commit.

Scores are out of 10 on each criterion, weighted per the methodology above, and reflect our assessment based on the research described in this article rather than a lab-tested benchmark. Sender and Brevo lead specifically because they scored well on the two heaviest-weighted criteria: free plan generosity and included features. Mailchimp’s strong ease-of-use score wasn’t enough to offset its now-thin free tier.

Frequently Asked Questions

Choosing a free email marketing tool sounds simple until you compare contact limits, sending caps, automation, and upgrade costs. Here are the answers to the questions users ask most before picking a platform. 

Is free email marketing software really free?

Yes, in the sense that you won’t be charged unless you exceed the plan’s limits or want a feature that’s paid-only. It’s not free in the sense of being unlimited. Every tool here caps something: contacts, sends, features, or branding removal.

How many emails can I send for free?

It varies widely. Systeme.io technically allows unlimited sends on its free plan, capped only by 2,000 contacts. Sender allows 15,000 emails a month. Mailchimp and Omnisend cap you at 500. Check the comparison table above for the full breakdown.

Does free email marketing software include automation?

Sometimes. Brevo, Sender, MailerLite, Systeme.io, and Omnisend all include some automation on their free plans, though often with a rule or contact-count cap attached. Mailchimp and HubSpot strip automation from the free tier entirely.

Which free email marketing tool is best for ecommerce?

Omnisend, because it includes native Shopify and WooCommerce integration plus pre-built abandoned cart and welcome flows on the free plan. The tradeoff is a tight 500-email monthly cap once your store starts sending regularly.

Do I need a credit card to sign up for a free plan?

No, for any of the nine tools in this guide. All of them let you create a free account without entering payment details.

What happens to my contacts if I go over the free plan limit?

This differs by tool. Some, like Mailchimp, pause sending until you upgrade or trim your list. Others, like Systeme.io, archive contacts above the limit rather than deleting them, and restore access once you’re back on a qualifying plan. Check the specific tool’s policy before you’re at the limit, not after.

Can I remove the vendor’s branding from a free plan?

Usually only by upgrading to a paid plan. Brevo, Sender, GetResponse, and Systeme.io all place branding on free-plan emails or pages that comes off only once you pay, sometimes as a separate add-on even after upgrading.

What’s the best free email marketing software for a small business just starting out?

If you’re starting from zero contacts, Sender’s combination of subscriber and send limits gives you the most runway before you need to pay anything. If you already have a bigger list you email occasionally, Brevo’s contact allowance is hard to beat.

Final Thoughts

If there’s one thing this research made clear, it’s that “free email marketing software” isn’t a fixed category. It’s a moving target, and 2026 has been an unusually active year for vendors quietly shrinking what “free” means.

Sender and Brevo currently offer the most room to grow before you’re forced to pay. Mailchimp, despite the name recognition, now offers the least. Everyone else falls somewhere between, depending on whether you care more about automation, a bundled landing page, ecommerce features, or an existing CRM.

Whichever one you pick, re-check its actual pricing page before you commit. Given how much has changed in the last eight months alone, it’s worth five minutes to confirm the numbers in this guide still match what’s live today.
