# Mailchimp vs MailerLite: One Raises Your Bill Without Asking, the Other Waits for You to Notice

> Mailchimp against MailerLite on measured ground: the automatic-upgrade rule, two different definitions of a billable contact, send multiples against unlimited sending, and two free tiers that both stop at 250.

---

This is the comparison people actually search for. Mailchimp against MailerLite draws
1,180 searches a month across both directions, more than any other pairing in this category that
we can write about honestly.

And the two products answer the same question in opposite ways, which makes the comparison unusually
clean. When your list outgrows your plan, one of them raises your bill without asking and the other
waits for you to notice.

**OUR TAKE:** MailerLite is cheaper at the entry, more generous on its free tier, and will upgrade
you automatically. Mailchimp is dearer, documents more, and will never change your tier by itself.
Which of those is the feature and which is the risk depends entirely on whether you would rather
be surprised by a charge or by a stopped campaign. A note on what this comparison is. We have measured Mailchimp in full: its pricing pages read as served from the United States, its terms read end to end, its ratings counted with the shared-ownership platforms counted once, and one hundred reviews cross-tabulated by theme. For the other product we read its own pricing page, served the same day from the same American address, and nothing else. No feature testing, no support testing, no review analysis. When that product gets its own cluster this article will be rewritten rather than appended to.

## The entry prices, as each vendor publishes them

| Product | Published entry | Basis the vendor states | Dollar amounts in visible text | Annual rate published |
|---|---|---|---|---|
| Mailchimp | $13 Essentials, $20 Standard | 500 contacts, promotional for 12 months | 12 | no, sales-gated above 10,000 contacts |
| MailerLite | $12 Comfort, $25 Power | starting price, subscriber-based | 3 | not in visible text |

MailerLite publishes the fewest figures of any rival in this category that publishes any, which is
the one place where Mailchimp is the clearer of the two. Three amounts, and both of the paid ones
are described as starting prices rather than as prices.

Mailchimp's twelve figures include four distinct prices, and every paid one is discounted fifteen
percent for twelve months, with the rate afterwards unpublished to an American reader[8].

So neither page lets you price your own growth. They fail at it differently. Both fail.



> 💡 **undefined:** Ask MailerLite what the next pricing tier costs before you are automatically moved into it. Automatic upgrade is a feature only if you know the destination.

## The difference that matters most: what happens at the limit

MailerLite states the paid-plan rule in its own words: for paid accounts, when the number of active
subscribers exceeds the current subscriber limit, the limit increases automatically and the card is
charged for the next pricing tier[23].

Mailchimp does the opposite, and is equally explicit. You choose the band and it is yours until you
change it: "Your maximum contact count determines your pricing tier."[7] Exceeding it produces
a surcharge rather than a new tier, and the vendor tells you whose job the fix is: "If the increase
is permanent, update your pricing tier to increase your contact limit, and we'll remove the
additional charges."[5]

Read those two rules beside each other and the choice is a temperament rather than a calculation.
With MailerLite the campaign goes out and the invoice moves. With Mailchimp the invoice gains a
surcharge that keeps running until somebody acts.

On the free tiers the two converge. MailerLite locks sending at 250 active subscribers[23];
Mailchimp places a hold at 250 contacts[5]. Same ceiling, same consequence. Identical, in effect.

## Which contacts you pay for

This is where the real money is, and the two definitions differ enough to change which product is
cheaper for the same list.

Mailchimp bills subscribed, unsubscribed and non-subscribed contacts, and excludes archived,
cleaned and deleted ones[5]. Archiving is a documented lever you operate yourself, and it
preserves the contact's data and reports[15].

MailerLite bills active subscribers, and publishes a timing rule that catches people: if you delete
subscribers on the first and your billing date is the fifth, those subscribers keep counting until
the fourth[23].

Mailchimp has a timing rule too, and it is harsher: the bill is computed on "the peak contact total
during your billing period", so a reduction mid-cycle does not help that cycle at all[6].

Work out your own list under both definitions before comparing headline prices. For a list with
many past unsubscribes the gap between the two totals is larger than the gap between twelve dollars
and thirteen.



> 💡 **undefined:** Count your list under both definitions. Mailchimp bills unsubscribed contacts and excludes archived ones; MailerLite bills active subscribers.

## Sending allowances, which are not the same unit

Mailchimp allowances sends as a multiple of the contact limit: ten times on Essentials, twelve on
Standard, fifteen on Premium[5]. At the entry band that is five thousand and six thousand sends
a month.

MailerLite's Power plan advertises unlimited monthly emails, subject to a fair use policy, and its
Comfort plan carries a monthly allowance that refreshes at the billing cycle[23]. The vendor
tells you what to do when you hit it: upgrade to Power for unlimited sending, or wait for the
allowance to refresh[23].

Those are not comparable numbers, and any comparison table that puts them in one column is
misleading you. A multiple of your list size scales with your list. An unlimited allowance subject
to fair use scales with the vendor's patience.

If you send frequently to a small list, the multiple is the binding constraint and MailerLite's
model is better. If you send rarely to a large list, the reverse.

## The free tiers

Both cap at 250, and that is where the similarity ends.

MailerLite's free plan includes 2,500 monthly emails, all three of its email editors, campaigns,
automations, a website, a landing page and signup forms, plus an MCP connector for Claude and
ChatGPT[23]. API and MCP sending are reserved for paid plans[23].

Mailchimp's free plan includes 500 monthly emails with a daily cap of 250, one audience, and a
limited template selection[5]. Fifteen capabilities read "Not included" in that column,
including email scheduling, A/B testing, dynamic content and the generative AI features[3].
Support is email only and only for thirty days[3].

Five times the monthly sends on one side. On the other, a free tier that cannot schedule an email.

For anyone evaluating with a real list rather than a test list, MailerLite's free tier is the more
useful trial of the actual product.



> 💡 **undefined:** Divide monthly sends by list size before comparing price. Above twelve, Mailchimp's multiple is your constraint whatever the headline says.

## Where Mailchimp is clearly ahead

Documentation, and it is not close. Mailchimp publishes the expensive answers without being asked:
the peak-total billing rule, which contact statuses are billable and which are not, the send
multiple for each tier, the send allowance each overage block carries, and the
cancellation path through to the final click[6][5][16].

On our scale Mailchimp earns 3.8 on the documentation axis, the highest mark we have given any
product on it.

Usability evidence is the second place. Across the two app stores Mailchimp carries 74,983 ratings
at 4.9 and 4.7, and the interface is the only review theme its users name more often in praise than
in complaint, at 13% of high reviews against 3% of low ones. We have no comparable measurement for
MailerLite, because we have not measured it.

## Where MailerLite is clearly ahead

Price certainty. MailerLite's figures are starting prices rather than promotional ones, so there is
no twelfth-month cliff to plan around. Mailchimp's card price rises by a derived fifteen twenty-nine,
twenty-three fifty-three or four hundred and eleven seventy-six in month thirteen, depending on
tier.

Generosity at the bottom. Five times the free sends, and the full feature set on every paid plan by
the vendor's own description[23].

And an enterprise path that is stated rather than implied: custom pricing above 200,000 subscribers
with unlimited user seats and a dedicated success manager[23]. Mailchimp routes everything
above 250,000 contacts to sales as well, but its published Premium ceiling has five different
answers across its own pages, which is a less comfortable place to start a negotiation.




> ⚠ **undefined:** MailerLite counts deleted subscribers until your billing date. Mailchimp bills on the peak contact total of the whole period.

## The demand, and why this pairing comes first

We measured which comparisons people actually search for before deciding which to write, and this
one leads the category among products we can write about honestly: 1,180 searches a month across
both directions.

Behind it sit Mailchimp against ActiveCampaign at 520, against Kit at 520, against Brevo at 350,
against GetResponse at 140 and against Beehiiv at 130.

Two larger pairings exist and we cannot serve them yet. Mailchimp against Constant Contact draws
1,600 and Mailchimp against Klaviyo 720, and neither product is in our catalogue. We say so rather
than quietly omitting them, and the vendor's own comparisons hub names Klaviyo more often than any
other rival, which suggests the market and the vendor agree about the competitive set.

So this article is the largest comparison we can honestly make, not the largest that exists.

## The ratings, and how to read them

Mailchimp carries five independent readings and they disagree sharply: Trustpilot 2.5 from 1,538,
Gartner Peer Insights 4.3 from 1,268, TrustRadius 8.4 out of 10 from 2,885, the App Store 4.9 from
51,654 and Google Play 4.7 from 23,329.

Two cautions, measured rather than assumed. A displayed score is not the mean of the platform's own
published distribution: Trustpilot shows 2.5 where its histogram averages 2.08, and Gartner shows
4.3 where its histogram averages 4.40. Both weight toward recency and here they push in opposite
directions.

And the app stores measure the application while the review platforms measure the commercial
relationship. Seventy-five thousand ratings at nearly double the score is not a contradiction; it
is two different questions.

We have no equivalent figures for MailerLite, because we measured its pricing page and nothing
else. Any score you see quoted for it in a comparison article, including the absence of one here,
should be treated accordingly.



> ⚠ **undefined:** Mailchimp's card price is promotional for twelve months and the rate afterwards is not published to an American reader.

## What neither page lets you do

Price your own growth. That is the honest summary of both pricing pages, and it is worth stating
because it is the thing a buyer most wants.

Mailchimp publishes twenty contact bands and the price of two of them, with the selector that would
reveal the rest served disabled in the American markup[2]. Its ceilings are three hundred and
eighty-five dollars at 50,000 contacts and eight hundred at 100,000, printed on a comparison page
nothing links to[3].

MailerLite publishes three figures, two of them described as starting prices, and an enterprise
tier above 200,000 subscribers with custom pricing[23].

So in both cases you can price today and not next year. The difference is that MailerLite will move
you up the ladder automatically when the time comes, and Mailchimp will leave you on a surcharge
until you move yourself.

Neither is a reason to pick one. Both are a reason to ask for the ladder in writing before you
start.

## What the review themes say about living with Mailchimp

A comparison built on pricing pages tells you what signing up costs. The reviews tell you what the
year afterwards is like, and we read one hundred of them in full and sorted them by star rating.

| Theme | Share of 1-2 star reviews | Share of 4-5 star reviews | Gap |
|---|---|---|---|
| Billing and charges | 33% | 3% | +30 |
| Support | 52% | 26% | +27 |
| Cancellation | 17% | 0% | +17 |
| Locked out of the account | 16% | 0% | +16 |
| Price and increases | 11% | 0% | +11 |
| Contact limit | 3% | 0% | +3 |
| Interface | 3% | 13% | -10 |

Four of those rows are commercial and one is about access to your own account. The contact limit,
which the whole of this comparison has been about, appears in three percent of unhappy reviews.

That is a useful corrective. The pricing structure is where the money is, but it is not where the
anger is. The anger is in billing disputes, in support that does not answer, and in sixteen percent
of low reviewers describing days spent trying to get back into an account they pay for. None of
those appear in any feature table.

The row that runs backwards matters too. The interface is named more often in praise than in
complaint, which is rare in this corpus, and it is supported by 74,983 app store ratings at 4.9 and
4.7. People like using this software.

So weigh the pricing analysis for the signing-up decision and the review analysis for the
staying decision. They point in different directions and both are measured.



> ⚠ **undefined:** We measured MailerLite's pricing page only. No feature, support or review testing, and this article will be rewritten when that product gets its own cluster.

## A worked example, on the same list

Take a list of nine thousand people built over three years. Six thousand five hundred are active
subscribers, two thousand have unsubscribed, and five hundred are dead addresses the platform has
already cleaned.

On Mailchimp that list is eight thousand five hundred billable contacts, because unsubscribed
contacts count and cleaned ones do not[5]. That puts it in the five thousand to ten thousand
band. An archiving pass on the two thousand unsubscribes would move it to six thousand five
hundred, which is the same band, so in this case the lever does not save money. At nine thousand it
would have.

On MailerLite that list is six thousand five hundred active subscribers, and when it crosses
whatever the next band is, the tier moves and the card is charged automatically[23].

Two things follow. First, the same people produce two different numbers, and the gap is the two
thousand unsubscribes. Second, the archiving lever only pays when it moves you across a band
boundary, which means the habit is worth most to accounts sitting just above one.

Work out where your own boundaries are before deciding which product is cheaper. The headline
dollar between twelve and thirteen is noise next to a two-thousand-contact definitional difference.

## Three things we could not compare

Support. We have published entitlements for Mailchimp and the review evidence above, and nothing at
all for MailerLite. We did not open tickets with either vendor, so neither support assessment rests
on our own experience.

Deliverability. Neither vendor publishes rates we could verify, and both make claims. We measured
neither and we are not going to repeat marketing copy as a finding.

Feature depth. We read two pricing pages. Mailchimp's plan comparison table gave us 225 counted
cells[3]; MailerLite's page describes its tiers in prose and says every paid plan gets the full
feature set[23]. Those are not comparable artefacts, and a feature table built from them
would be a guess wearing a grid.

## How to choose, in three questions

Would you rather be charged without asking, or have a campaign held? That single question separates
these two products more than any feature.

Does your list carry a lot of past unsubscribes? If so, price it under both definitions, because
Mailchimp's archiving lever can move your band and MailerLite's active-subscriber basis may already
exclude them.

And how often do you send relative to your list size? Divide monthly sends by subscribers. Above
twelve, Mailchimp's multiple becomes the constraint and MailerLite's unlimited Power plan is the
simpler answer.



## FAQ

**Is MailerLite cheaper than Mailchimp?**

At the published entry, by one dollar: twelve against thirteen. But Mailchimp's thirteen is discounted fifteen percent for twelve months and the rate afterwards is unpublished, while MailerLite's twelve is described as a starting price. Over twenty-four months the comparison is not close to the one the headline numbers suggest.

**Does MailerLite upgrade your plan automatically?**

Yes, on paid accounts. The vendor states that when active subscribers exceed the current limit, the limit increases automatically and the card is charged for the next pricing tier. Mailchimp does the opposite and never changes your tier by itself.

**Which has the better free plan?**

Both cap at 250, and MailerLite gives five times the monthly sends at 2,500 against 500, plus all three email editors and an MCP connector. Mailchimp's free tier cannot schedule an email or run an A/B test.

## What we would check before committing either way

For Mailchimp, ask for the list price for your band in writing before the promotional twelve months
start, and ask the price of an add-on contact block, which is the unit every overage is charged in
and is published nowhere[6].

For MailerLite, ask what the next pricing tier costs before you are automatically moved into it,
because automatic upgrade is only a feature if you know the destination. Ask where the fair use
line sits on unlimited sending. And ask how active subscriber is defined, since that definition is
the meter.

Then compare two annual totals rather than two monthly prices. The headline dollar between these
two products is the least informative number in the comparison.
