Best Free Email Marketing Tools in 2026
Eleven email platforms with free tiers that actually send campaigns, not just store contacts.
Brevo gives you unlimited contacts and 300 emails a day for free, the best fit for small businesses that need volume over fancy segmentation. ConvertKit (rebranded Kit) lets creators build a list up to 10,000 subscribers before paying a cent. beehiiv is built for newsletter publishers who want unlimited sends up to 2,500 subscribers, and Klaviyo remains the strongest free pick for ecommerce stores that need behavioral automation from day one.
Most "free" email marketing tools cap you at 100 contacts and call it a day, and a few, like ActiveCampaign, don't offer a free plan at all, just a 14-day trial. Of the 10,000+ tools Toolradar tracks, 25 in the Email Marketing category offer a genuine free tier, and even fewer of those let you actually send an automated welcome sequence or an ecommerce cart-abandonment flow without paying. Free tiers change fast too: Mailchimp cut its free plan to 250 contacts and 500 sends in January 2026, and Mailerlite trimmed its own free limits in June 2026, so a list built on outdated pricing info gets a nasty surprise at signup.
We verified every pick below against each vendor's current pricing page in August 2026, checked that the tool is still actively maintained, and confirmed the free tier lets you send real campaigns, not just draft them. We dropped tools whose free trial gets marketed as a free plan and anything whose real free tier had been quietly cut or killed. What's left are 11 platforms ranked by how much you can actually do before your card gets asked for.

Value 85/100. Brevo's pricing is quite competitive, especially at the entry level.
Watch out: Email volume increases cost significantly

Value 78/100. ConvertKit's pricing is fair for creators, with a generous free tier up to 10,000 subscribers.
Watch out: Price scales significantly with subscribers

Small teams who want a familiar, well-documented tool and don't need a large free list.
Value 50/100. Mailchimp was once the default email marketing tool for small businesses, and its free tier was legendary.
Watch out: ALL contacts count: subscribed, unsubscribed, non-subscribed, and 'cleaned' contacts all count toward your plan limit. You pay for contacts who unsubscribed last year unless you manually archive them. This inflates costs by 20-40% for most lists
Ecommerce stores that want behavioral automation, like cart abandonment, from day one.
Value 70/100. Klaviyo offers a genuinely useful free tier (250 contacts, 500 emails/mo) but costs escalate rapidly with list growth, from $30/mo at 1,000 contacts to $150/mo at 10,000 and $1,380/mo at 100,000.
Watch out: Since Feb 2025, you pay for ALL active profiles, not just contacts you email. Imported but unengaged contacts still count toward billing

Other Email Marketing worth considering
Beyond the editorial top picks, these are also strong choices we evaluated.
What Is an Email Marketing Tool?
An email marketing tool, also called an ESP or email service provider, lets you build a subscriber list, design campaigns, and send them at scale without getting flagged as spam. It handles the parts individual senders can't do reliably on their own: deliverability infrastructure, unsubscribe compliance, list segmentation, and performance tracking like opens and clicks.
Most platforms in this category also bundle automation (welcome sequences, abandoned-cart flows, drip campaigns), landing pages, and signup forms, so you can capture and nurture subscribers in one place instead of stitching together separate tools.
Why Free Email Marketing Tiers Matter
Email remains one of the highest-ROI marketing channels, but most platforms price by contact count or send volume, both of which climb fast once you actually have an audience. A genuine free tier lets you validate that email is worth the investment, or worth switching platforms, before you commit budget.
The catch is that "freemium" varies wildly in what it actually includes. Some free plans cap you at 100 contacts with no automation; others give you thousands of subscribers and full automation for free. Knowing the real limits before you build your list on a given platform saves you a painful migration later.
Key Features to Look For
Some free plans cap you by contacts, others by monthly or daily sends. Check both before assuming a free tier fits your list.
Welcome sequences and drip campaigns shouldn't require a paid plan. Confirm automation isn't locked behind an upgrade.
A tool that requires a card for its "free" plan is often running a trial with an auto-charge trap, not a real free tier.
A free sender IP shared with spammers can hurt inbox placement. Look for platforms with dedicated deliverability infrastructure even on free tiers.
Check the first paid tier's price at your expected list size, not just the free plan, so growth doesn't come with sticker shock.
Most free plans keep vendor branding in the email footer. Decide whether that matters for your audience before committing long-term.
Mistakes to Avoid
- ×
Assuming "freemium" means the free tier is enough to launch, without checking today's actual subscriber and send caps. Several vendors cut free limits in 2026.
- ×
Building a list on a free plan without checking whether the contact count includes unsubscribed and suppressed profiles, which can silently fill up your quota.
- ×
Picking a tool by name recognition alone, like Mailchimp or HubSpot, instead of checking whether the current free tier fits your list size.
- ×
Ignoring daily send caps versus monthly caps. A 300-a-day plan behaves very differently from a 9,000-a-month plan if you send in bursts.
- ×
Not confirming automation is included free. Some tools sell automation as a paid add-on even though the base send limit looks generous.
Expert Tips
- →
Match the cap to your list, not your ambition. If you have 300 subscribers today, beehiiv's 2,500-subscriber free plan gives more runway than Buttondown's 100-subscriber ceiling.
- →
Check whether pricing is contact-based or send-based. Brevo's send-based model (unlimited contacts, capped sends) suits large dormant lists better than Klaviyo's contact-based caps.
- →
If you're ecommerce, prioritize a tool with cart-abandonment automation included free, like Klaviyo or Omnisend. Generic newsletter tools don't offer this on their free tier.
- →
Re-verify free tier limits before you commit. Both Mailchimp and Mailerlite cut free-tier limits in 2026, so an older comparison post is no longer accurate.
- →
Budget for the day you outgrow the free plan, not just the sign-up. Compare the first paid tier's price at your expected list size, not just the free plan's cap.
The Bottom Line
Brevo and beehiiv offer the most usable free tiers for most people right now: unlimited contacts with a daily send cap on one side, unlimited sends up to 2,500 subscribers on the other. ConvertKit remains the pick if you want the largest free subscriber ceiling before paying anything. Of the 10,000+ tools Toolradar tracks, 25 in the Email Marketing category offer a genuine free tier, and the 11 above are the ones where that free tier actually lets you send real campaigns.
Frequently Asked Questions
What is the best free email marketing tool in 2026?
There's no single best option; it depends on your list size and use case. Brevo offers unlimited contacts with 300 emails a day, ConvertKit allows up to 10,000 free subscribers, and beehiiv gives unlimited sends up to 2,500 subscribers. Ecommerce stores are better served by Klaviyo or Omnisend, which include cart-abandonment automation for free.
Is Mailchimp still free in 2026?
Yes, but the free tier shrank significantly. As of January 2026, Mailchimp's free plan covers only 250 contacts and 500 sends a month, down from far higher limits in previous years. If you need more room, Brevo or ConvertKit currently offer more generous free tiers.
Which email marketing tool has no send limit on the free plan?
Does ActiveCampaign have a free plan?
Can I run an automated welcome sequence on a free email marketing plan?
Yes, several tools include automation for free. Loops, Omnisend, and Klaviyo all offer pre-built automation flows, like welcome series and cart abandonment, on their free tiers. ConvertKit's free plan, by contrast, limits you to one basic automation rule.
