Mailchimp's Free Plan: Its Own Page Gives Two Limits

Is Mailchimp free? Yes, up to a contact cap — and when we read mailchimp.com's own pricing page on September 23, 2026, it stated that cap two different ways. One section says "Under 250 contacts? It's free." Another, further down the same page, says "If your business has fewer than 500 contacts, try our basic Free plan." Those are different numbers describing the same plan, on the same page, on the same day.

We don't know which is current policy and which is stale copy, so this site prints neither as fact. What we can do is show you exactly what the page says, what surrounds the free plan, and which competitors publish free tiers without the ambiguity.

What the page actually says

The free plan is pitched for starting out: "use core features to manage early growth. Move to a paid plan as you scale." The pricing page we read does not itemise the free tier's send allowance, seat count or feature list the way it itemises the paid grid — those specifics live deeper in Mailchimp's docs and change often enough that we quote only the pricing page itself. What it does make unmistakable is the direction of travel: the free plan is the top of a funnel whose first paid rung is Essentials, from $13 a month at 0–500 contacts once the 50%-off first year is spent.

The two-number problem matters for a practical reason: 250 versus 500 contacts is the difference between a free plan that covers your list next quarter and one that doesn't. If your list sits between those numbers, the only reliable move is to sign up and see where the product itself draws the line — or to pick a platform whose page commits to one figure.

The upgrade cliff, priced

Whichever cap applies, outgrowing it lands you on the paid ladder, and the first steps are steep in percentage terms: Essentials at $13 and Standard at $20 a month at 0–500 contacts (post-offer), then $26 and $45 at 501–1,500 — the band boundary where a growing free-plan list first meets real money. The full band-by-band walk is on our Mailchimp pricing page; the short version is that "free" ends not with a small bill but with a schedule of them.

Free plans that publish one number

Read the same day, on each vendor's own pricing page:

Two of these — Sender and EmailOctopus — publish free ceilings of 2,500 subscribers, five to ten times Mailchimp's two candidate numbers. They're smaller platforms with plainer feature sets, which is the honest trade. MailerLite's 250 matches Mailchimp's lower figure exactly but is stated once, without contradiction. And Brevo's free plan is a different shape altogether — a 300-a-day drip rather than a monthly pool — which suits some senders perfectly and campaign-day senders not at all.

What we'd actually do

For a list already near 500: don't build on a cap the vendor describes inconsistently — start on a platform whose free plan holds 2,500 (the free-alternatives ranking compares five), or price the paid tiers honestly against each other in the full comparison, where the paid entry rows start at $9 a month. For a list of 50 testing an idea: any of these free plans works, Mailchimp's included; the cap won't be your problem for a while, and moving early is cheap. Either way, when a pricing page can't agree with itself, believe the product over the copy — and keep your export clean so the next move stays easy.

"Core features": what the page commits to, and what it doesn't

The free plan's one description on the pricing page — "use core features to manage early growth" — is doing a lot of unspecified work, so it's worth being precise about what we can and can't tell you from the page itself. What it commits to: the plan exists, it costs nothing, it is aimed at businesses below some sub-500 contact count, and it sits beneath a paid ladder whose first rung is Essentials. What it doesn't specify there: the monthly send allowance, the seat count, which editor features and templates are included, whether automation is present at all, and what happens — pause, prompt, or hard stop — at the cap. Those details exist in Mailchimp's product documentation, but documentation moves faster than pricing pages and faster than review sites; any third-party article confidently listing "the free plan includes X sends and Y features" is quoting a snapshot that may already be stale, ours would be no different, and that is why this page quotes only what the pricing page itself says.

There's a useful general lesson in the two-number problem beyond this one vendor. Free tiers are the most frequently edited objects in SaaS pricing — they're marketing levers, tightened when acquisition costs rise and loosened when growth stalls — and MailerLite's current 250-subscriber cap is itself the product of exactly such an edit. Building a program on any free tier therefore means accepting policy risk you don't control. The mitigation costs nothing: keep your list exported on a schedule, keep your signup forms swappable, and know your next rung's price at two vendors rather than one. A sender who can move in an afternoon is a sender no pricing-page edit can ambush — which, not coincidentally, is the sender this whole site is trying to help you become.

One more practical note for the reader between 250 and 500 contacts, since that's whom the discrepancy actually bites: whichever figure turns out to be enforced, you are at most one growth quarter from the paid ladder either way. Planning as if the cap were the lower number costs you nothing if the higher one is true, and saves a surprise if it isn't — which is the general rule for ambiguous vendor copy, and the last time this page will make you read it.

If Mailchimp's page has resolved its two numbers into one by the time you read this, believe the page over this article — and we'd genuinely appreciate a note about it, since documenting the discrepancy accurately is this guide's entire job.
