MailerLite vs Mailchimp: The 2026 Verdict for Small Business Budgets 

Quick comparison table

Is MailerLite really cheaper, or does it catch up at scale?

In the mailerlite vs mailchimp price comparison, MailerLite stays cheaper at every published tier, but the gap narrows as lists grow. At 500 subscribers, MailerLite’s Comfort plan runs $12/month against Mailchimp’s Essentials at $13/month, barely a difference. At 1,000 subscribers, MailerLite’s Comfort climbs to $19/month while Mailchimp’s Standard sits around $20/month for a comparable feature set. At 5,000 subscribers, MailerLite’s Comfort is $49/month versus Mailchimp’s Standard at roughly $100/month, here the gap widens hard in MailerLite’s favor. At 10,000 subscribers, MailerLite’s Power plan runs $129/month for unlimited sending and automations, while Mailchimp’s Premium tier, the one with unlimited emails at that volume, starts at $350/month.

The pattern: MailerLite’s pricing scales close to linearly with list size. Mailchimp’s pricing scales in steps, and the step up to Premium at 10,000+ contacts is brutal. If you plan to stay under 5,000 contacts forever, the difference is not decisive. If you plan to grow past 10,000, MailerLite’s cost advantage becomes the whole argument.

Annual billing saves roughly 10% on MailerLite. Mailchimp’s annual discount exists too, but neither vendor publishes exact percentages transparently enough to state a single verified number for both, check the live checkout before committing to a year upfront.

Does Mailchimp really charge you for unsubscribed contacts?

Yes. Since April 2024, Mailchimp counts subscribed, unsubscribed, and non-subscribed contacts toward your billable total. The only contacts excluded are cleaned, pending, deleted, and archived contacts, and archiving is a manual step you have to remember to do. If you run a list with normal churn and never clean it, you end up paying every month for people you will never email again.

MailerLite does not do this. It bills active/subscribed contacts only. For a business with high churn, course sellers, event marketers, anyone running paid ads into a list, this single billing rule can be the deciding factor on its own, independent of the headline price.

There’s a second cost trap buried in Mailchimp’s list architecture: lists are mutually exclusive. If the same person sits on two different segments, say, “customers” and “webinar attendees”, Mailchimp can count them twice toward your contact total. MailerLite’s list management doesn’t force this duplication. Buyers running multiple overlapping segments pay more on Mailchimp for structural reasons that have nothing to do with list size.

What do you actually get on each free plan in 2026?

Both free plans got worse in the past year, and both now cap at 250 contacts. MailerLite cut its free tier from 500 subscribers to 250 on 16 June 2026, as part of a wider restructure that also renamed its paid plans (Growing Business became Comfort, Advanced became Power) and raised paid prices 10-30% across every tier. Mailchimp cut its free plan from 500 to 250 contacts on January 2026, continuing a pattern that’s seen its free tier shrink from 2,000 contacts in 2022 to 250 in 2026, an 87.5% reduction in four years, since Intuit’s $12 billion acquisition in 2021.

Beyond the contact cap, the free plans diverge sharply on sending volume. MailerLite’s free plan allows 2,500 monthly emails; Mailchimp’s free plan caps at 500 monthly sends with a hard daily limit of 250 emails. Mailchimp’s free plan also carries branding on every email, no scheduling, no multi-step automation, and support that ends 30 days after signup. MailerLite’s free plan includes 3 automations, a landing page, a website, and community support with no time limit.

Any comparison article you find online that quotes “500 subscribers free” for either tool, or refers to MailerLite’s “Growing Business” or “Advanced” plans, was written before these changes and is stale.

Which one is faster to set up if you’ve never sent a campaign?

MailerLite is faster to a first campaign because it does less. The interface has fewer menus, fewer settings screens, and a cleaner automation builder, reviewers consistently note MailerLite’s builder is less cluttered than Mailchimp’s, which carries years of accumulated UI debt from features bolted on since the Intuit acquisition. If you’ve never used an email tool before, that difference matters in the first hour, not just the first month.

Mailchimp’s setup takes longer because it’s asking you to configure a broader platform, websites, SMS add-ons, transactional email via Mandrill, multiple audience types, even if you only want to send a newsletter. That breadth is a genuine advantage for someone who wants one vendor for everything. It’s friction for someone who just wants to email a list.

For a business that’s been running physical operations and wants a simple digital add-on, the kind of small operator who might also be reading our Hisense 65E7KQ QLED TV review for a break-room upgrade rather than researching enterprise software, MailerLite’s narrower tool is the one that gets a first campaign out the same afternoon.

How deep does automation go before you hit a wall?

Both tools gate meaningful automation behind their mid-tier plans, and both have a hard ceiling reviewers flag as too low for behavioral marketing. On MailerLite, single-trigger automations are available on Comfort ($12/mo+); multi-trigger workflows require Power ($25/mo+). Neither tier offers a page-visit trigger, if you want to fire an email because someone viewed a specific product page, MailerLite cannot do it at any price.

Mailchimp’s automation gate sits differently: one-step automation on Free and Essentials, multi-step journeys only on Standard ($20/mo+) and above. Mailchimp’s automation ceiling is higher in absolute terms, send-time optimization, dynamic content, and journey builders exist that MailerLite doesn’t match, but it costs more to reach.

The honest read: neither tool is built for lead scoring or complex multi-channel journeys. Users who outgrow welcome sequences on MailerLite hit what reviewers openly call an “automation ceiling.” If your business genuinely needs mid-workflow entry points or scoring, you’re shopping for a dedicated automation platform, not either of these.

Where does each tool genuinely fall apart?

MailerLite’s biggest documented weakness is account suspension without warning. Multiple G2 reviews describe sudden account termination tied to bounce rates, with no advance notice, a pattern one reviewer summarized as “documented cases even with excellent metrics.” This is strict list-hygiene enforcement that catches users with older or imported lists, and it’s a recurring theme, not an isolated complaint. MailerLite also has no phone support at any tier, no native transactional email or SMS (both require a separate MailerSend account), and fewer native integrations, roughly 143 versus Mailchimp’s 300+.

Mailchimp’s biggest documented weakness is billing pain, and it compounds. G2 reviewers describe cost as “absurd,” specifically calling out that small businesses are “penalized for having a larger email list.” Billing support is close to non-existent for payment issues, no phone line for billing problems, a support form with a 3-4 day wait, while the charge has already gone through. Some users report Mailchimp shifting to a two-tier billing model that charges inflated prices for small contact-block increases rather than moving customers to a cheaper adjusted plan. At scale, the interface itself draws complaints: broken multi-column layouts in Outlook, poor mobile rendering, and a mobile app one reviewer called “particularly bad.”

Trustpilot ratings reflect this gap starkly: MailerLite sits at 4.1/5 from 3,279 reviews; Mailchimp sits at 2.6/5 from 1,456 reviews. On G2, both score better, MailerLite 4.6/5 from 1,109 reviews, Mailchimp 4.3/5 from 12,698 reviews, but the Trustpilot gap, where billing and support complaints concentrate, is the widest number in this whole comparison.

How hard is it to move from Mailchimp to MailerLite?

Moving from Mailchimp to MailerLite is the best-documented direction, and MailerLite built a dedicated importer for it. The 1-click Mailchimp Importer brings subscribers, tags, custom fields, and segments across in minutes, no CSV exports, no manual field mapping. You connect via login credentials or an API key, and Mailchimp tags convert into MailerLite groups automatically, with subscriber organization preserved and segments based on static fields recreated on the other side.

What doesn’t move: templates and automations. Templates need to be rebuilt manually in MailerLite’s editor, expect a few hours depending on how many you use. Automation workflows also require manual rebuilding; the importer only moves contact and list data, not campaign or automation logic.

Going the other direction, MailerLite to Mailchimp, relies on standard CSV export and import. No dedicated one-click tool for this direction turned up in research; Mailchimp’s own marketing only references generic “migration tools” without naming a specific MailerLite integration, so treat any claim of a reciprocal one-click importer as unconfirmed.

One lock-in risk worth flagging before you commit to Mailchimp long-term: disconnecting Shopify from Mailchimp triggers a warning that synced Shopify data will be deleted and can’t be undone. If your business runs e-commerce through Mailchimp, factor that into any future exit plan now, not later.

Neither platform offers hands-on migration support for free-tier or self-serve users, both position themselves as self-serve, and the actual work of importing contacts or recreating automations is on you either way.

Which tool wins in real buying scenarios?

Solo freelancer with 800 subscribers and no automation needs beyond a welcome email: MailerLite wins on price ($19/mo Comfort at 1,000 subscribers vs. roughly $20/mo Mailchimp Standard for similar features) and on setup speed. Nothing about Mailchimp’s extra breadth matters here.

Two-person agency managing client email plus Shopify integration for a retail client: Mailchimp wins, but with eyes open about the exit cost later. The 300+ integrations and established Shopify sync outweigh MailerLite’s price advantage for this specific use case, as long as the agency understands disconnecting later means losing synced data permanently.

Course creator with a list that churns 15% a year from refunds and unsubscribes: MailerLite wins decisively. Mailchimp would bill for every unsubscribed contact indefinitely unless the creator manually archives them every month. MailerLite’s active-only billing means the churn doesn’t cost anything once those contacts leave.

Small business scaling from 2,000 to 15,000 contacts within two years: MailerLite wins on trajectory. At 10,000 contacts, MailerLite’s Power plan runs $129/month with unlimited sending; Mailchimp’s Premium tier for the same volume starts at $350/month, nearly triple. Unless the integrations at Mailchimp are load-bearing for the business, this cost gap becomes hard to justify by year two.

What mistakes do buyers make choosing between these two?

When weighing mailerlite vs mailchimp, the most common mistake buyers make is pricing a plan by headline number instead of by your actual contact count trajectory. A $12/mo starting price means nothing if you’re already at 8,000 subscribers, check the scaled price at your real list size, not the “starts at” figure, on both mailerlite.com/pricing and mailchimp.com/pricing/marketing directly.

The second mistake is ignoring list hygiene until it costs money. On Mailchimp, an unmanaged list of unsubscribed contacts quietly inflates your bill every month. On MailerLite, an unmanaged list of hard bounces can trigger the account suspensions reviewers report, going the opposite direction, from cost creep to sudden shutdown. Either way, clean your list before you pick a plan tier.

The third mistake is assuming deliverability numbers are settled fact. Sources on this materially disagree: one 2026 benchmark puts MailerLite at 94.41% average deliverability against Mailchimp at 82-85%; a separate independent test found MailerLite closer to 80% with a 20% flagged-as-spam risk against a competitor at 95%; a third benchmark puts Mailchimp at 92.6%. These numbers contradict each other directly. Don’t choose a tool based on a single deliverability stat you found in one article, including this one. Test with your own list and content before betting your revenue on either vendor’s claimed number.

The fourth mistake is underestimating rebuild time during migration. Templates and automations don’t move automatically in either direction. Budget real hours for rebuilding, not “a quick import.”

Frequently asked questions

Is MailerLite cheaper than Mailchimp for every list size?

Yes, at every published tier MailerLite’s price stays below Mailchimp’s for a comparable feature set. The gap is small at 500 subscribers ($12 vs. $13) and grows large by 10,000 subscribers ($129 vs. $350). It never flips in Mailchimp’s favor at published prices.

Does Mailchimp charge for unsubscribed contacts?

Yes. Mailchimp counts subscribed, unsubscribed, and non-subscribed contacts toward your billable total. The only contacts excluded are cleaned, pending, deleted, and archived ones. If you never manually archive dead contacts, you keep paying for them.

Will I lose my templates moving from Mailchimp to MailerLite?

Yes, templates don’t transfer automatically. MailerLite’s importer moves contacts, tags, and segments, but you’ll rebuild templates and automations manually in MailerLite’s editor, plan for a few hours depending on how many you have.

Why did MailerLite’s free plan get worse in 2026?

MailerLite cut its free plan from 500 to 250 subscribers on 16 June 2026 as part of a full plan restructure, also renaming Growing Business to Comfort and Advanced to Power and raising paid prices 10-30% across every tier.

Which has better deliverability, MailerLite or Mailchimp?

Sources disagree materially. One 2026 test put MailerLite at 94.41% against Mailchimp’s 82-85%; another put MailerLite at roughly 80%; a separate benchmark put Mailchimp at 92.6%. There’s no single verified answer, test both with your own content before deciding.

Does MailerLite have automation as advanced as ActiveCampaign?

No. Reviewers consistently describe an “automation ceiling” on MailerLite, it handles simple, behavior-based sequences well but lacks lead scoring, mid-workflow entry points, and page-visit triggers at any tier.

Is Mailchimp worth it for a small business in 2026?

Only if you need its integration breadth or are already committed to its e-commerce sync. Since Intuit’s 2021 acquisition, Mailchimp has raised prices or cut free-plan limits nearly every year, and billing support for payment issues is widely reported as slow.

What happens if my MailerLite account gets suspended?

MailerLite enforces strict list-hygiene rules, and G2 reviewers document sudden suspensions tied to bounce rates without advance warning, even for accounts with otherwise good metrics. Keep your list clean and remove hard bounces regularly to reduce this risk.

Which should you choose?

MailerLite is the right default for most readers of this site: solo founders, freelancers, and small teams running lists under 10,000 contacts who don’t need a sprawling integration library. It costs less at every tier, bills you fairly for the people who actually stay subscribed, and gets a first campaign out faster because the interface doesn’t make you wade through features you’ll never touch.

Don’t buy MailerLite if you have a messy, unverified, or purchased list, the documented suspension risk is real, and it will cost you more in downtime than the price difference saves you. Clean your list first, then switch.

Mailchimp is the right choice only for a narrower group: businesses with existing deep e-commerce integrations, or teams that genuinely use 10+ native integrations Mailchimp offers and MailerLite doesn’t. Everyone else is paying an escalating bill, partly for contacts who’ll never open another email, to fund features they don’t use.

If you’re currently on Mailchimp and considering the switch, MailerLite’s built-in importer removes most of the friction, you’ll rebuild templates and automations by hand, but your contact list moves in minutes. Compare MailerLite’s current plans here before your next Mailchimp renewal date hits.
