Best Free Email Marketing Tools in 2026
Every email tool has a free plan and every free plan stops in a different place. That is the entire decision, and comparison tables almost never show it.
Mailchimp caps you at 500 contacts. Brevo caps you at 300 emails a day but lets you store unlimited contacts. beehiiv gives you 2,500 subscribers. Those are three completely different constraints, and which one hurts depends on something you already know about yourself: whether you have a big list you email rarely, or a small list you email constantly.
I pulled the current free tiers in August 2026. Here is where each one actually stops.

Ratings aggregated by Toolradar across G2, Capterra, Trustpilot and SourceForge. Mailchimp's figure needs the explanation below before you read anything into it.
Notice that only one of these limits sends rather than contacts. That single difference reorders the list depending on your situation.
The Mailchimp number, and what it actually means
Mailchimp aggregates to 3.9 across 31,952 reviews, the lowest score and by far the largest sample in this comparison. Taken alone that looks damning for the category's best-known product. Broken apart it is more interesting.
Mailchimp scores 4.5 on Capterra across 17,595 reviews, 4.3 on G2 across 12,946, and 2.6 on Trustpilot across 1,411. Business software buyers rate it well. Consumers rate it badly. Same product, same year, a gap of nearly two points.
This is the sharpest example we have of something that shows up across our whole directory. G2 and Capterra collect reviews from people who chose software for an organisation and can be verified as customers, often shortly after a purchase decision they are invested in. Trustpilot collects reviews from anyone, and people who are content with an email tool rarely go there to say so.
Neither number is fake. They answer different questions. If you are asking whether Mailchimp does the job a business needs, the 4.5 from seventeen thousand Capterra reviewers is the relevant figure. If you are asking what happens when your account gets flagged and you need support, the 2.6 is the one telling you something.
Everywhere else in this table the platforms broadly agree, which is why we are singling this one out rather than quietly averaging it away.
Brevo: unlimited contacts, capped sends
Aggregated rating 4.6 across 5,959 reviews (4.5 on G2, 4.6 on Capterra). Brevo's free plan allows 300 emails a day with unlimited contacts stored, then starts at about $9 a month on Starter and $18 on Business.
This is the outlier and often the right answer. If you have five thousand contacts you email once a month, every contact-capped tool wants money from you immediately and Brevo does not. You are only constrained on the day you send, and 300 a day is 9,000 a month if you drip it.
It is also a broader product than the newsletter tools: transactional email, SMS, a basic CRM and automation are all in the same account. That makes it a reasonable spine for a small business rather than only a broadcast tool.
The daily cap is the catch. If you want to email six thousand people on Tuesday, you cannot, and no amount of unlimited contacts fixes that.
beehiiv: the biggest free subscriber allowance
Aggregated rating 4.5, across only 49 reviews, so treat it as thin. beehiiv's free Launch plan covers up to 2,500 subscribers, with Scale at $43 a month or $517 a year covering 100,000 subscribers and three seats.
That free ceiling is five times Mailchimp's, and it comes with the newsletter-native features: a hosted web archive, referral programs, recommendation networks and a decent ad marketplace once you are large enough to care.
The trade is scope. beehiiv is built for publications, not for e-commerce lifecycle email. If your emails are triggered by orders and behaviour rather than published on a schedule, this is the wrong shape and Brevo or Mailchimp will fit better.
The jump from free to $43 is also steep in one step, though what you get for it, a hundred thousand subscribers, makes the per-subscriber cost very low.
Mailchimp: the default, with the tightest free tier
Aggregated rating 3.9 across 31,952 reviews, explained above. Mailchimp is free up to 500 contacts, then roughly $13 a month on Essentials, $20 on Standard, and $350 on Premium.
It remains the most familiar tool in the category, with the largest template library and the deepest integration list. If you use an e-commerce platform, Mailchimp is already supported, and that saves real setup time.
But 500 contacts is the smallest free allowance here, and Mailchimp's pricing then scales with contacts rather than sends. For a list that grows quickly and sends rarely, this is the most expensive shape in the comparison.
Worth knowing before you commit: contacts that unsubscribe can still count toward your tier depending on how your audience is configured. Audit that before renewal.
MailerLite: the clean middle
Aggregated rating 4.7 across 1,179 reviews (4.6 on G2, 4.8 on SourceForge), the highest here on a meaningful sample. MailerLite's free plan covers a limited subscriber count and monthly send volume, with paid tiers scaling by list size.
Its reputation is deserved on one axis in particular: the editor is the least annoying in this group. Building a decent-looking email takes minutes rather than a fight with a drag-and-drop grid, and the landing page builder is genuinely usable.
It sits between the newsletter tools and the marketing suites. Automations exist and are competent without being deep. If Mailchimp feels heavy and beehiiv feels too publication-shaped, this is the tool people land on.
Check the current free thresholds directly, because MailerLite has adjusted them more than once and the exact numbers move.
Kit: built for creators
Kit, formerly ConvertKit, offers a free plan for a limited subscriber count, then paid tiers by list size.
Kit's model is tagging rather than lists, which sounds like a detail and changes how you work. One subscriber, many tags, and automations that branch on behaviour. For a creator selling several things to overlapping audiences, that is the correct mental model and Mailchimp's list-based approach fights you.
The templates are plain by design, on the theory that plain text converts better from a personal sender. If your brand needs a designed email, that is a real limitation rather than a philosophy you will enjoy.
The cost the free tiers hide
None of these plans mention the thing most likely to waste your first month: sending domain setup.
On a free plan you are usually sending from a shared pool of IP addresses alongside every other free user of that platform, including the ones sending things nobody asked for. Your deliverability is partly their behaviour. That is a reasonable trade at zero cost, and it is why a campaign that looks fine in the dashboard can land in promotions or spam.
Two things materially help and both are free. Authenticate your domain properly with SPF, DKIM and DMARC records, which every tool here documents and most people skip. And send from a subdomain you control rather than the platform's default, so your reputation accrues to you and travels with you if you switch.
The second point is the one that matters at the twelve-month mark. If you build a sending reputation on a vendor's domain, migrating means starting from nothing. Set it up correctly on day one and changing tools later costs you a weekend rather than a quarter of degraded inbox placement.
How to choose
Answer one question first: are you contact-constrained or send-constrained?
If you have a large list you email occasionally, Brevo is the only free plan here that does not punish you, because it counts sends rather than contacts.
If you are publishing a newsletter, beehiiv gives you the most room at 2,500 subscribers free and the tooling that assumes a publication rather than a store.
If you run e-commerce and want the integrations to already exist, Mailchimp is worth the tight 500-contact free tier, and you will be paying within a quarter anyway.
If you want the nicest editor, MailerLite. If you sell multiple products to overlapping audiences, Kit's tagging model will save you from rebuilding your automations in a year.
The mistake to avoid is choosing on the free tier alone and discovering the paid curve afterwards. Mailchimp scales with contacts, beehiiv scales in large steps, Brevo scales with volume. Model your list at twelve months, not today.

FAQ
Which email marketing tool has the best free plan?
It depends on your shape. Brevo's is the most generous for large lists because it stores unlimited contacts and limits you to 300 emails a day instead. beehiiv's 2,500 subscribers is the largest contact allowance. Mailchimp's 500 contacts is the tightest of the group.
Can I run a real business on a free email plan?
Yes, for a while, and Brevo makes it last longest because a growing list does not force an upgrade. What forces the upgrade is usually not volume but a feature: removing vendor branding, adding a second seat, or an automation the free tier withholds.
What does email marketing actually cost after the free tier?
Entry paid plans run from about $9 a month on Brevo and $13 on Mailchimp Essentials to $43 on beehiiv Scale, which covers 100,000 subscribers. MailerLite and Kit both price by list size. Figures checked August 2026.
Should I use a newsletter tool or a marketing platform?
If your email is published on a schedule to people who chose to read it, use a newsletter tool like beehiiv or Kit. If your email is triggered by what someone did on your site, use a marketing platform like Brevo or Mailchimp. Using the wrong one is survivable and you will feel the friction weekly.
Which email marketing tool is rated highest?
MailerLite, at 4.7 across 1,179 aggregated reviews, followed by Brevo at 4.6 across 5,959. Mailchimp's 3.9 is the lowest and comes from by far the largest sample, 31,952 reviews, but it splits sharply by platform: 4.5 on Capterra and 2.6 on Trustpilot. Read that spread rather than the average.
Is Mailchimp still worth using?
For a business that wants the deepest integration library and templates that work out of the box, yes, and its Capterra and G2 scores from thirty thousand business reviewers support that. The complaints concentrated on Trustpilot are mostly about support and account handling rather than the product doing its job, which is a real consideration if you are running something you cannot afford to have interrupted.
