# Klaviyo vs Mailchimp in 2026: One Publishes Two Ends of a Ladder, the Other Publishes a Point

> Klaviyo 3.88 against Mailchimp 3.46, measured on the same eight axes: how each one fails to publish its ladder, what the free tiers really differ on, and which direction each bill travels by itself.

This is the comparison people actually run. `klaviyo vs mailchimp` and `mailchimp vs klaviyo`
together draw 1,440 searches a month, which is six times the next pairing in this category. It
is also the only comparison Klaviyo itself publishes against an email tool: its other comparison
pages take on Attentive, Listrak, Postscript and Salesforce Marketing Cloud, which are SMS and
enterprise platforms [18].

We have measured both products from their own pages, read from the United States, and scored
them on the same eight axes. Klaviyo takes 3.88 and Mailchimp 3.46. What follows is where that
gap comes from, and the two or three places where it reverses.

## The short answer

Klaviyo is the deeper product and Mailchimp is the more legible one. If you sell to consumers
and run on Shopify, Klaviyo will do things Mailchimp cannot attempt. If you want to know what
you will pay in month seven, Mailchimp gets closer, and neither gets all the way there.



> 💡 **undefined:** Compare the second year, not the first. Every Mailchimp card price is fifteen percent off for twelve months; Klaviyo's twenty dollars is a standing rate with a one-month credit.

## Neither one publishes its ladder, and they fail differently

This is the most useful thing to understand before comparing prices, because it shapes every
number below.

Mailchimp publishes the floor of its ladder on one page and the ceiling on another. Its pricing
page carries $13, $20 and $350 as entry-band rates and $0 for free; its comparison page adds
$385 at fifty thousand contacts and $800 at one hundred thousand. Between those it publishes
twenty contact bands and the price of none of them, and the selector that would reveal them is
served to a United States reader with the `disabled` attribute.

Klaviyo publishes no email tier price on its pricing page at all. 601,147 characters of markup
yield thirty-two dollar amounts, none of them an email tier, and the only profile counts in the
whole page are the free plan's 250 and 500 [2]. Its one published email price, twenty
dollars, appears in the legal terms of a discount [4].

So: Mailchimp gives you two ends and no middle. Klaviyo gives you one point and a method. Both
leave the buyer's own band unpriced, which is the thing the buyer came for.

## What the entry looks like

| | Klaviyo | Mailchimp |
|---|---|---|
| Free plan | 250 profiles, 500 sends, plus $5 mobile and $5 Composer | 250 contacts, 500 sends a month, 250 a day |
| At the limit | sending stops until you reduce | a hold is placed on sending |
| Entry paid price | $20 a month, published in a discount's terms | $13 Essentials, $20 Standard, at 500 contacts |
| Is the entry price promotional? | no, but a $19 first-month credit exists | yes, fifteen percent off for twelve months |
| Annual option | none published | stated to exist above 10,000 contacts, sales-gated |

The free tiers look identical and are not. Both give 250 and 500. Klaviyo adds five dollars of
mobile messaging and five dollars of AI composer usage on top, renewing monthly [2].
Mailchimp adds a daily send cap of 250 and limits support to email for the first thirty days.
For anyone wanting to test SMS or AI before paying, that is a real difference.

The promotional structure is the other asymmetry. Every paid figure on Mailchimp's card is
discounted fifteen percent for twelve months, and the rate that follows is the central number it
does not publish for a United States reader. Klaviyo's twenty dollars is a standing price with a
one-month credit attached, so what you see is what month two costs.



> 💡 **undefined:** If you test SMS or AI before paying, Klaviyo's free tier includes allowances for both and Mailchimp's does not.

## What the bill looks like after that

Mailchimp bills on contacts, counting subscribed, unsubscribed and non-subscribed alike, and
excludes archived, cleaned and deleted ones. Sends are a multiple of the contact limit: ten
times on Essentials, twelve on Standard, fifteen on Premium.

Klaviyo bills on active profiles, meaning anyone still reachable by at least one channel, and
meters email sends separately rather than as a multiple. Its published example is an $80 plan
carrying 35,000 monthly emails, a CPM of $1.14 [6].

The practical consequence is that the two products reward different hygiene. On Mailchimp,
archiving is the lever, and it is documented. On Klaviyo, suppressing or deleting is the lever,
and the timing matters more than the action, because the count that bills you is the one at the
end of the cycle [5].

## What each one counts, and what it forgives

The billing unit is where two products that look alike stop being alike, and both vendors
document theirs properly.

Mailchimp counts contacts, and it counts them generously: subscribed, unsubscribed and
non-subscribed all bill. What it forgives is archiving. An archived contact keeps its data and
its reporting history and leaves the invoice, and the vendor documents this as a deliberate
lever. Cleaned and deleted contacts also stop billing. So on Mailchimp the question is not who
is on your list but who is in an unarchived state at the moment of billing, and that moment is
the peak of the billing period rather than its end.

Klaviyo counts active profiles, which it defines by reachability rather than by consent history:
a profile bills if it can still receive at least one kind of marketing. What it forgives is
suppression and deletion. The difference from Mailchimp is the timing: the count that matters is
the one at the end of the billing cycle [5].

Two consequences follow for anyone running campaigns. On Mailchimp, growing and pruning a list
inside one cycle is charged at the largest the list reached. On Klaviyo, the same sequence is
charged at where it ended, so pruning before the cycle closes genuinely helps. That is a real
operational difference and it runs opposite to what most people assume.

One more asymmetry worth naming: a reviewer of Klaviyo reports being "charged almost three times
my normal monthly bill because of profiles that were obviously generated during
development/testing" [20]. Reachability-based counting treats a staging environment writing
to production as customers.



> ⚠ **undefined:** Neither vendor publishes the price of your actual band. Get it in writing before signing either contract.

## Sends: a multiple against a meter

Mailchimp attaches sends to contacts as a fixed multiple: ten times the contact limit on
Essentials, twelve on Standard, fifteen on Premium. You cannot buy more sends without buying
more contacts, and you cannot buy more contacts without more sends.

Klaviyo meters the two separately. Its published example is an $80 plan carrying 35,000 monthly
emails at a CPM of $1.14, with the next tier at 50,000 [6]. Profiles and sends move on
different ladders, and the account can cross one limit without touching the other.

This matters most for two opposite shapes of business. If you have a large list you mail rarely, a seasonal retailer say, Mailchimp's multiple gives you headroom you do not pay extra for,
while Klaviyo charges for the profiles regardless. If you have a modest list you mail often,
Mailchimp's multiple becomes the binding constraint and Klaviyo's separate send meter is the
cheaper shape.

Neither vendor frames it this way on its pricing page, and it is frequently the difference
between the two bills.

## The direction of travel, which is Klaviyo's real cost

Mailchimp's published behaviour at a band crossing is a surcharge that continues until somebody
changes the tier by hand. Klaviyo's is an automatic upgrade: "You will be automatically upgraded
to a profile-compliant plan at the end of each billing cycle, if you exceed your level of
profile usage" [5], with auto-upgrade "toggled on by default" [11].

Coming back down is where Klaviyo asks more of you. The plan "does not automatically downgrade
when you reduce profiles" [5]; the downgrade must happen more than twenty-four hours before
the cycle turns; it does not take effect if it is later; there are no refunds for mid-cycle
downgrades; and an outstanding invoice blocks it [5]. An auto-downgrade preference exists
but "can be used with flexible sending but not with auto-upgrade" [11], so enabling it means
replacing the default rather than adding to it.

Seventeen of a hundred Trustpilot reviewers raise exactly this, and all seventeen are one or
two-star reviews [20]. Only five in a hundred say the product is too expensive.



> ⚠ **undefined:** Klaviyo's plan climbs by default and descends only when you arrange it. Mailchimp's band crossing starts a surcharge that also continues until someone acts.

## Capability, where the gap is largest

| Axis | Klaviyo | Mailchimp |
|---|---|---|
| Capability and depth | 4.5 | 3.8 |
| AI | 4.2 | 3.0 |
| Documentation | 4.0 | 3.8 |
| Integrations | 3.8 | 3.6 |
| Ease of use | 3.9 | 3.8 |
| Value for money | 3.7 | 3.4 |
| User sentiment | 3.2 | 3.0 |
| Support and reliability | 2.7 | 2.4 |

Klaviyo scores higher on every axis, which is unusual and worth being explicit about. The gap is
widest on capability and AI, and those two carry most of it.

Klaviyo runs six channels off one profile (email, SMS, RCS, mobile push, WhatsApp and social)
and sells a helpdesk, an AI support agent, a loyalty-aware customer portal and a data platform
the vendor says holds 7.3 billion consumer profiles [12]. Mailchimp has none of those four.
For a business that wants a mailing tool, that is irrelevant. For one consolidating its customer
record, it is the whole decision.

On AI, the difference is terms rather than features. Both have AI. Klaviyo publishes what it
costs: Composer at twenty dollars a month with $5 included and $10 per 1,000 credits beyond,
Customer Agent at fifty dollars for seventy-five resolved conversations [5]: and names the
models it connects to, publishing Claude and ChatGPT connectors and an MCP server [15]
[16]. Mailchimp publishes the features and not the rates.

## Where Mailchimp is the better answer

Three places, and they are real.

If you are not an ecommerce business, Klaviyo's depth is weight you carry without using. The
guided setup, the abandoned-checkout flows and the loyalty portal all assume a store. Mailchimp
is more neutral about what you sell.

If you want a price before a conversation, Mailchimp publishes more of one. Two ends of a ladder
beat one point on it, even when both leave your band unpriced.

And if your list is small and static, the downgrade asymmetry never fires, which removes
Klaviyo's main practical risk and leaves you comparing two entry prices that are the same twenty
dollars.

## Where Klaviyo is the better answer

If you sell to consumers through a store, if your question is which message goes to which
segment and what it earned, or if you expect to add SMS or a support channel to the same
customer record, Klaviyo is a different class of product and the score reflects it.

The Shopify evidence is worth weighing directly: 4.7 out of 5 from 3,362 reviews on the app
store where this product is actually installed, against Mailchimp's listing on the same store
at 4.8 from 1,509 [19]. Both are well-liked where they are used. Klaviyo has more than
twice the review volume there, and the vendor says over 117k brands run it with Shopify.

## Where each one stops publishing

Both vendors leave gaps, and the gaps are differently shaped.

Mailchimp does not publish the monthly list price of any tier in the United States, which is the
figure that applies from month thirteen when the promotional period ends. It does not publish
the price of eighteen of its twenty contact bands. It does not publish any rate for its Pay As
You Go credits, and it does not publish an annual price on any tier. It also gives five
different published answers for the ceiling of its Premium tier across four pages and one data
payload, which is a different kind of problem.

Klaviyo does not publish the price of any email tier above the entry one, the number of tiers,
the profile band attached to the twenty-dollar plan outside a promotional banner, its
per-message mobile rates by country, its volume-discount curve, the ceiling of any plan, or any
annual price at all.

The lists are similar in length. The difference is that Mailchimp's gaps sit inside a published
structure, you can see the bands even when you cannot see their prices, while Klaviyo's gaps
include the structure itself. A Mailchimp buyer knows there are twenty bands. A Klaviyo buyer
does not know how many there are.

## What the reviews say about each

We read both corpora rather than the badges, and the comparison is instructive.

Klaviyo on Trustpilot shows 1.6 out of 5 from 369 reviews, with a hundred-review corpus whose
mean is 1.54 and whose one-star share is eighty-two percent [20]. Mailchimp shows 2.5 from
1,538. Neither is a random sample: people arrive at a complaint platform with a complaint, and
the corpus is the output of that selection rather than of the customer base.

The app stores tell the opposite story for both. Klaviyo takes 4.7 from 3,362 reviews on the
Shopify App Store; Mailchimp's listing on the same store shows 4.8 from 1,509, and its mobile
apps carry 4.9 and 4.7 from 74,983 ratings between them [19].

The useful signal is in the themes rather than the scores. In Klaviyo's corpus, support appears
in fifty-nine of a hundred reviews and billing in thirty-one, while only twenty-two touch
features at all. The complaints are about the commercial machinery, not the software. Mailchimp's
negative corpus is similarly dominated by billing. This appears to be a category pattern: in
email marketing, people rarely leave because the product is bad.



## FAQ

**Is Klaviyo better than Mailchimp?**

On our eight axes Klaviyo scores higher on all of them, 3.88 against 3.46, with the largest gaps on capability and AI. That does not make it the right choice for everyone: if you are not an ecommerce business, much of the depth it is scored for is weight you carry without using.

**Which is cheaper, Klaviyo or Mailchimp?**

At the entry band they are close: twenty dollars for Klaviyo Email and thirteen or twenty for Mailchimp Essentials and Standard at five hundred contacts. The Mailchimp figures are promotional for twelve months and the rate afterwards is not published for a United States reader, while Klaviyo's twenty is a standing price. Above the entry band neither publishes enough to compare.

**Can I move from Mailchimp to Klaviyo?**

Technically yes, and Klaviyo publishes a comparison page aimed at exactly that move. The cost that surprises people is not the contact import but the flows and the attribution history, neither of which transfers. Budget parallel running rather than a cutover.

## How to decide in one question

Ask what you want the customer record to hold. If the answer is an email address and a few
tags, buy the simpler product and keep your attention for something else. If the answer is
orders, behaviour, loyalty balance and support history on one profile, Klaviyo is built for
that and Mailchimp is not, and the price you will argue about later is the price of a platform
rather than a mailing list.

Then, whichever you choose, get your band's price in writing before you sign. Neither vendor
publishes it.
