MailerLite vs Mailchimp (2026): The Switcher's Comparison

MailerLite wins this matchup on price at every list size we checked, and it isn't close: $12 against $45 a month at 1,000 contacts, $49 against $100 at 5,000, both read on the vendors' own pages on September 23, 2026. Mailchimp's case rests on its integration catalogue, its bigger template and reporting surface, and the 50%-off first year — real advantages that stop mattering to some senders the day the promo ends.

MailerLite is the single most common destination for people leaving Mailchimp, so this head-to-head does the thing generic reviews skip: it prices the actual move, at your size, on both billing terms.

The prices, side by side

MailerLite's Comfort plan against Mailchimp Standard — the tiers a typical small sender would genuinely run. MailerLite figures are monthly billing; its yearly billing shaves each price (Comfort at 500 subscribers drops from $12 to $10.80 a month, billed as $129.60 a year). Mailchimp's page shows monthly prices only, and these are its post-offer figures.

Notice where the gap explodes: Mailchimp's 501–1,500 band. Crossing 500 contacts more than doubles Mailchimp Standard to $45, while MailerLite's step to 1,000 subscribers costs $7 more. Band edges are where Mailchimp bills hurt, and the first edge arrives earliest.

What the counting unit hides

MailerLite counts subscribers; Mailchimp counts contacts. The words sound interchangeable and are not: each platform's documentation defines which stored addresses — unsubscribed, bounced, never-confirmed — count against your tier. Before trusting any row above at your real list, check how each platform treats your dead weight; a list that's 20% unsubscribes is a different bill under different definitions. We flag the unit on every platform we compare on the alternatives page for exactly this reason.

Send caps and seats

Mailchimp Standard caps sends at 12× your contacts and includes 5 seats and 5 audiences. MailerLite Comfort includes 3 seats, and its send allowance is listed as 5,000 monthly emails at its smallest size — MailerLite's Power tier ($25 a month at 500 subscribers, monthly billing) is the one with unlimited emails and unlimited seats. A daily-newsletter habit outgrows both platforms' entry tiers; on that pattern, price MailerLite Power against Mailchimp Standard rather than Comfort.

Free plan against free plan

MailerLite's free plan is unambiguous: up to 250 subscribers, 2,500 monthly emails, 2 seats, with 3 automations and a landing page included. Mailchimp's free plan is the one its own pricing page couldn't describe consistently on the day we read it — "under 250 contacts" in one section, "fewer than 500 contacts" in another — a discrepancy we document in the free-plan guide rather than resolving by guesswork. If a genuinely roomy free tier is the goal, neither is the answer: Sender and EmailOctopus both publish 2,500-subscriber free plans.

Where Mailchimp still wins

Three honest points for the incumbent. Its integration directory is the largest in small-business email, and if your store, CRM or booking tool has a first-class Mailchimp integration and a second-class MailerLite one, that difference can outweigh every row in the price table. Its reporting and template ecosystems are deeper. And its intro offer means a new project that will genuinely stay under 500 contacts pays $10 a month for Standard in year one — cheaper than MailerLite Comfort's list price, until month thirteen flips the sign.

The verdict, sized

At 5,000 contacts, switching Comfort-for-Standard saves $51 a month at list prices — $612 a year — for a platform that covers the campaign, form, landing-page and basic-automation core most senders at that size actually use. The smaller your list, the smaller the saving and the stronger Mailchimp's integration argument. Rebuilding automations is the real moving cost either way: list yours before you export, and walk through the full comparison if this matchup didn't settle it.

Rebuilding your Mailchimp setup, piece by piece

Price settles the destination; the move itself is a translation exercise, and it helps to know what translates cleanly before you commit. Contacts travel best: export your Mailchimp audience as a CSV — take the unsubscribe and cleaned lists too, because carrying suppressions over is a legal obligation, not an optional tidy — and import at the other end. Expect the organising concepts to shift under you as you do it: what Mailchimp scatters across tags, groups and segments you will re-express in the destination's own grouping model, and the mapping is a judgment call only you can make, so do it while the Mailchimp account is still open for reference rather than from memory a week later.

Three rebuilds don't translate and have to be redone by hand anywhere you go. Automations are the big one — flows exist as configurations, not data, so list every live automation before you export and rebuild each in the new builder, simplest first, testing with a seed address. Templates are the second: plan to rebuild your master template rather than chasing a pixel-faithful copy, since editors differ in how they construct layout. Signup forms are the third, and they come last in the sequence for a reason — the moment your website's forms point at the new platform is the moment the migration actually happens, so schedule it after your sending domain is authenticated there (fresh SPF and DKIM records from the destination's setup screen) and after one clean test campaign has gone out.

Give the whole exercise a quiet week on the calendar rather than an afternoon. The pattern that produces horror stories is a same-day cutover with no overlap; the pattern that produces boring successes is two platforms running side by side briefly, forms switched once sending is proven, and the old account closed only after its final billing date is understood. On a $51-a-month gap at 5,000 contacts, even a slow, careful move pays for its own labour inside the first quarter.

A closing note on billing terms, since the two pages differ: MailerLite's yearly discount is a standing rate you keep, while Mailchimp's 50%-off is a first-year event that ends. Comparing a durable discount against a temporary one is the classic mistake in this matchup, and every table above avoids it on purpose.
