Klaviyo vs Mailchimp: Mailchimp Is Cheaper Until It Is Not

Someone asked this exact question on Reddit recently. They sell a luxury product, have under 150 contacts, can’t imagine passing 5,000, and their store’s on Wix. The thread told them Mailchimp was probably the better choice, and the thread was right.

So let’s start there, because it’s the fastest way to be useful: if that description fits you, stop reading and use Mailchimp. It’s cheaper, it’s easier, and the things Klaviyo does better are things you’ll never touch. This page is about the point where that answer flips, and what changes when it does.

We’re a Klaviyo agency, so weigh this accordingly. Klaviyo Elite Master, 2025-2026. Every number below is sourced to each company’s own pricing page, read on 24 September 2026, and where Mailchimp makes our argument better than we could, we’ve quoted them.

Key Takeaways

• Mailchimp’s cheaper than Klaviyo right up until it isn’t. At 5,000 contacts Klaviyo and Mailchimp Standard are both $100 a month. Above that, Standard’s cheaper and the gap grows.
• But Mailchimp Premium costs more than Klaviyo at every size we checked - $465 against $350 at 15,000 contacts, $815 against $720 at 50,000. Which matters, because the support Mailchimp advertises against Klaviyo is a Premium feature.
• The real difference is what each one gates. Mailchimp charges you by plan tier and by contacts. Klaviyo’s marketing plan charges by contacts, and the feature set comes with it.
• On the entry plan, Mailchimp caps automation at four flow steps. That’s on their own pricing page, and it won’t cover a welcome sequence with delays.
• Mailchimp’s send allowances beat Klaviyo’s by roughly a fifth. That one goes in their column and we won’t hide it.
• Mailchimp’s own comparison page concedes the argument, describing its advantage as applying to teams that “may not require advanced eCommerce-specific functionality”.
• Integration counts are close, 350+ against 300+. Anyone selling you a ten-to-one gap hasn’t checked.

What Mailchimp Says About Klaviyo, and What’s True

Mailchimp publishes a page called “Why choose Mailchimp over Klaviyo?” and you should read it before you read anybody’s opinion, ours included. The headline is “Stop overpaying for Klaviyo and start growing efficiently with Mailchimp”, and it makes four claims. Here they are, taken seriously.

“You can save up to 42% when you switch.” On their entry plans, plausible. We couldn’t reproduce the exact figure because it depends which Klaviyo plan and which list size you start from, but the direction’s right and the section below shows by how much at four list sizes.

“Klaviyo can become very expensive, very quickly as a business’s email list grows.” Against Mailchimp Standard, true. Against Mailchimp Premium, the opposite. Which of those is the fair comparison is the entire question, and we deal with it below instead of picking whichever flatters us.

“Klaviyo has email-based support, and prioritizes chat options for higher price tiers.” Fair. Mailchimp gives 24/7 email and chat support on its paid plans, and Klaviyo’s entry support is email. We said the same when we compared Klaviyo with Omnisend, and it still holds.

“Klaviyo is often described as having a steeper learning curve.” Also fair, and they cite a G2 report for it. We couldn’t open G2 to verify the specific finding, so treat it as their claim, but it matches what we see. Klaviyo’s a deeper tool and it behaves like one.

Four claims, three we’d broadly agree with. Now the part their page keeps out of the headline.

What Each One Actually Costs

Every figure below came off each company’s own pricing page on 24 September 2026, at the same contact counts, in US dollars, at the regular monthly rate and not a promotional one. For Klaviyo on its own, our full breakdown of Klaviyo pricing covers every profile tier and the ten products it meters separately.

Three things fall out of that table, and you can check all three in about five minutes.

At 5,000 contacts, Klaviyo and Mailchimp Standard cost exactly the same. One hundred dollars each. Whatever you’ve read about Klaviyo being the premium option, at the size most brands are actually at when they ask this question, it isn’t.

Against Mailchimp Standard, Mailchimp’s cheaper as you grow. A hundred and twenty dollars a month cheaper at 15,000 contacts, two hundred and seventy at 50,000. Their claim’s correct and we won’t argue with arithmetic.

Against Mailchimp Premium, Klaviyo’s cheaper at every size we checked. By $115 a month at 15,000 contacts, $185 at 30,000 and $95 at 50,000.

Why Premium is the comparison that matters

Because of what sits inside it. On Mailchimp’s own plan table, phone support and the dedicated onboarding specialist are Premium features. Their comparison page sells better support as a reason to leave Klaviyo. So the saving they advertise only holds while you stay on a plan that doesn’t include the support they’re advertising.

No gotcha intended. That’s the actual shape of the decision, and you should make it on the real numbers instead of the headline ones.

One point goes to Mailchimp. Their send allowances are more generous. Mailchimp gives you roughly twelve times your contact count in monthly emails; Klaviyo gives you about ten. At 5,000 contacts that’s 120,000 sends a month against 50,000. If you mail a small list very hard, that difference is real and it’s in their favour.

Mailchimp Gates by Plan. Klaviyo Gates by Contacts.

Here’s what a price comparison can’t show you, and it’s what decides whether you’re still happy in eighteen months.

Look at the first row. On Mailchimp’s entry plan, automation is capped at four flow steps. A welcome sequence of three emails with a wait between each is already five. We’re not calling that a flaw, it’s a packaging decision, and it’s on their own pricing page.

Now look down the column. Predictive segments are Standard and above. Generative AI features aren’t on the entry plan. The onboarding specialist is Premium only. Each of those is a perfectly reasonable thing to charge for. The cumulative effect is that in Mailchimp, your capability is a function of your plan and your list size, and you find the ceiling by hitting it.

Klaviyo’s marketing plan works the other way round: the price scales with profile count and the marketing feature set comes along. Klaviyo does sell separate products alongside it, and we’ll come to what those cost, but within email and its channels you’re not choosing between a cheaper version and a capable one.

A practitioner in that Reddit thread put it better than we can, describing running both for different clients: Mailchimp “keeps asking you to upgrade to a higher tier plan to use certain features and the amount of contacts you have, whereas Klaviyo lets you use everything and only charges you for the amount of contacts you have”. That’s the difference, from somebody with no reason to flatter either party.

The counter-argument, which deserves an answer

Also in that thread, someone who’d investigated this for a client concluded the opposite: “I haven’t found a single feature in Klaviyo that you can’t get in MailChimp. Pay more, get more.” Segmentation, Shopify integration, SMS, reporting, merging records, all present on both.

As a checklist, that’s correct, and any comparison pretending otherwise is lying to you. Both platforms have segmentation. What separates them isn’t whether the feature exists, it’s which plan it’s on, what limits it carries, and how much of your catalogue data it can see. A feature grid can’t show you that, which is why every feature grid on this topic concludes the two are basically the same and every practitioner who’s run both says they aren’t.

Audiences Versus One Customer Record

Mailchimp organises contacts into Audiences, and gives you three on the entry plan, five on Standard and unlimited on Premium. An Audience is a separate list with its own contacts. Klaviyo has one profile database, with events attached to each profile.

For a newsletter that distinction is academic. For a shop it isn’t. A business with a store, a wholesale line, a subscription programme and a newsletter either splits those into separate Audiences it can’t easily segment across, or keeps everything in one and loses the separation. The same person in two Audiences is two records that don’t know about each other.

This is the general-purpose versus ecommerce-native difference, expressed as a number you can check on a pricing page. Mailchimp serves every kind of business, from consultants to charities to shops, and a list-based model is the sensible way to serve all of them. Klaviyo only serves shops, so it could afford to assume everything hangs off a customer and their orders.

Neither choice is wrong. They’re answers to different questions, and yours is the one that matters.

Reporting, and the Concession Mailchimp Makes About It

Buried in Mailchimp’s own comparison page, in a list of their own disadvantages, sits this admission about their lower-tier plans: “some businesses find that Klaviyo’s lower-tier plans offer more comprehensive reporting”.

An unusually honest thing for a vendor to write about itself, and it points at something real. Reporting sounds like a nice-to-have until you try answering an ordinary commercial question with it. What’s a first-time buyer worth over twelve months compared with someone who came in on a discount code? Which flow is producing repeat orders instead of taking credit for them? Did last month’s revenue come from the campaign calendar, or from automations that would have fired anyway?

Those are attribution questions, and they’re only answerable if the platform holds orders against customers over time instead of counting opens and clicks per campaign. Same structural point as Audiences, wearing different clothes: a campaign-centric tool reports on campaigns, a customer-centric tool reports on customers.

The practical test before you commit to either: ask how you’d find out what a customer acquired through a specific discount code is worth a year later. If the answer involves exporting to a spreadsheet, you’ve learned what you needed to know about the reporting.

Klaviyo vs Mailchimp for Shopify

Most people asking this run a Shopify store, so it deserves a direct answer.

Both integrate with Shopify, and both sync your customers and your orders. What differs is what arrives and in what shape. A shallow integration gives you an order total, a date and an email address. A deep one gives you line items, variants, discount codes used, fulfilment status and refunds, stored as properties you can still segment and trigger on two years later.

Which is why the same request produces different amounts of work on each. “Email everyone who bought the 50ml size but not the 100ml” is a segment on one platform and a data project on the other. Neither vendor hides this; it follows from one of them being built only for shops.

Two practical notes for Shopify specifically. Some of Klaviyo’s newer additions, including its reviews product, are Shopify-only at the time of writing, so the advantage is largest exactly where most readers are. And if you’re not on Shopify, on Wix or Squarespace or a custom build, the gap narrows considerably, because the depth of the integration is where the advantage lives. Good reason to weigh the cheaper option.

A Worked Example: A Skincare Brand With 15,000 Contacts

Take a skincare business doing a few million a year. Fifteen thousand contacts, a cleanser, a serum, an SPF and some kits, about a third of revenue on subscribe-and-save, and one marketer who owns email among four other jobs.

On Mailchimp Standard, at $230 a month

A welcome journey, abandoned cart, a post-purchase sequence, a winback, and a campaign calendar. Predictive segments are included at this tier. The programme will work, the marketer can run it, and it costs $120 a month less than Klaviyo.

Friction starts at the second layer. Replenishment timing that differs by product, so the cleanser buyer and the SPF buyer are reminded on their own cycles instead of an average. Segments built on what someone bought instead of which campaign they opened. Separating the subscription cohort from one-time buyers without splitting them into another Audience. None of it’s impossible; all of it’s work, and some of it means moving up a plan.

On Klaviyo, at $350 a month

The first layer’s the same and takes about as long. What changes is the second layer, because the order data arrives structured: line items, variants, discount usage and fulfilment events as properties you can segment and trigger on later.

Which is what turns product-level replenishment timing into a setting instead of a project, and a subscription cohort into a segment instead of a separate list.

Framed honestly: that brand needs none of the second layer in month one. What the extra $120 a month buys is the absence of a ceiling. If you’re confident you’ll never reach for it, don’t pay for it.

The Rest of the Klaviyo Platform, and What It Adds

Klaviyo now sells more than a marketing tool. Its pricing page lists Marketing, Data + Analytics, Service, Composer and Customer Agent as separate lines, and as of 24 September 2026 the additional products start around $100 a month for Data + Analytics and around $200 a month each for Service and Customer Agent.

We’ve put that here and not in the price table on purpose, because including it there would let us claim a comparison we haven’t earned. The table above compares Klaviyo’s marketing product with Mailchimp’s marketing product. That’s the fair fight. The rest of the platform is available, it’s useful when a support conversation should suppress a promotional send, and it’s extra money.

The Three Layers, and Where Each Platform Stops

Nearly every email programme we audit is built in three layers, and the platform choice only bites at the third.

Layer one is the flows everybody has. Welcome, abandoned cart, post-purchase, winback, and a campaign calendar over the top. Both platforms do this well. If your programme lives here and it’s working, you haven’t got a platform problem, and this layer is most of the revenue a good programme produces. It’s also why a cheaper tool is so often the right answer.

Layer two is segmentation that reflects the business. Not “opened something in the last ninety days”, but “bought the serum on its own, never tried the kit, and is due a refill”. Here’s where the two separate, and it’s got nothing to do with the email editor. It depends on whether the line item, the variant and the discount code were stored as things you can query. Mailchimp does a useful version of this. It runs out of road earlier, and the workarounds are exports, extra Audiences and a higher plan.

Layer three is the programme reacting to things that aren’t marketing. Somebody with an open support ticket shouldn’t get the promotional send. Somebody who just downgraded a subscription needs a different message from somebody who cancelled. This layer’s where a customer database beats a sending tool, and it’s where the rest of Klaviyo’s product lines earn their money.

So the useful question when choosing isn’t which platform has more features. It’s which layer you’re on, and which one you intend to reach. If you’ll live in layer one indefinitely, buy the cheaper tool with a clear conscience. If your growth plan quietly depends on layer two, pick the one that holds the data properly, because reversing that decision later is expensive and making it now costs about the same.

Deliverability, and What Neither Vendor Will Tell You

People ask which platform has better deliverability. Close to the wrong question, and both companies are quietly relieved when you ask it, because your sending reputation is mostly yours and not theirs. Your list quality, your sending frequency and your consent practices do more than the platform does.

What does differ is the tooling round the problem. Whether you can isolate the unengaged with precision instead of a blunt date filter. Whether sunset rules can be automated instead of remembered. Whether you can watch engagement decay by cohort before it turns into an inbox placement problem. Those are segmentation capabilities wearing a deliverability hat, which puts the advantage in the same place as everything else on this page.

Two things hold whichever you pick. Sending to your whole list because you’re paying for it is the fastest way to wreck a sender reputation, and no platform will stop you. And switching resets nothing about list quality: if half your contacts haven’t opened anything in a year, they won’t start because the infrastructure changed. A good deal of what gets blamed on a platform is a hygiene problem that travelled with the list.

You Don’t Have to Work It Out Alone

The least discussed difference between these two isn’t a feature. Klaviyo has a large population of people who do this for a living, publish how they do it, and build tools round it. Whatever you’re trying to construct, somebody’s already written it up or will do it for you.

That matters more than it sounds, and the Reddit thread that prompted this page said it plainly: Klaviyo “isn’t intuitive”, so either learn to build the flows properly or bring in somebody who has. Fair description, and it cuts both ways. A deeper tool nobody drives is worse than a simpler tool somebody does, which is exactly why Mailchimp is the right answer for a lot of businesses.

If you do want the specialist route, these are our verified lists by situation. They exist because the ecosystem’s large enough to need sorting.

• The best Klaviyo agencies for DTC brands - the general shortlist, with every partner tier checked in the directory.
• Beauty and skincare - where shade and variant data decide whether a reminder lands.
• Health and wellness - where compliance shapes the copy.
• Subscription brands - for when churn, dunning and cancellation flows are the whole problem.
• London and the UK - both with trading status checked at Companies House.
• Elite Master agencies - if the top partner tier is a hard requirement.

And if what you actually want is the comparison against the other platform people weigh Klaviyo against, that’s Omnisend vs Klaviyo, built the same way.

Migrating From Mailchimp to Klaviyo

This is the most searched follow-up on the topic, and the answer has four parts.

The flows are the easy part. Rebuilding a welcome journey, an abandonment sequence and a post-purchase flow takes days, not weeks, and it’s a good moment to delete the three automations nobody’s opened since they were switched on.

Audiences become one database. This is the step people underestimate. If you’ve been running separate Audiences, deciding how they merge into a single profile list, and what happens to contacts who exist in several, is real work and it needs doing before anything gets imported.

History moves partially. Profiles and consent status move cleanly. Years of granular engagement history usually don’t, so behavioural segments need a rebuild period before you can trust them. Plan for that gap instead of being surprised by it.

Deliverability is the part that bites. A new sending setup has no reputation. Move the whole list and send a campaign to all of it on day one and you’ll have a bad month and blame the platform. Warming takes a few weeks, and skipping it is the single most common reason a migration gets judged a failure.

Five Things to Check on Your Own Account First

Most of this decision is answerable from your own data in an afternoon, and doing that beats reading another comparison. Including this one.

1. Count your real contacts, not your list. Both platforms price on contacts, and most lists carry a long tail of people who haven’t opened anything in a year. Work out how many are genuinely engaged, then price both platforms at that number. A list clean-up often changes the answer more than the platform choice does.

2. Write down the segment you most wish you could build. The one somebody asks for every quarter and never gets. Then check, on both platforms, whether the data it needs is actually being stored. That single question separates the two faster than any feature grid.

3. Count your flow steps. Sketch your ideal welcome sequence including the waits. If it comes to more than four steps, Mailchimp’s entry plan is already out and you should be pricing Standard.

4. Check how many lists you’re actually running. If your contacts are split across several Audiences you keep wishing you could query together, you’ve already met the structural limit, and moving up a plan treats the symptom.

5. Be honest about who’ll run it. If the answer is one person with four other jobs and no budget for help, weight ease of use heavily and pick the simpler tool. A programme that gets built beats a platform that could have been better.

When Mailchimp Is the Right Answer

We’d tell a business to pick Mailchimp, or stay on it, in all of these cases.

• You’re not really an ecommerce business. If email is newsletters, announcements and the occasional promotion, Klaviyo’s advantages are things you’ll pay for and never use.
• You’re small and expect to stay small. Under a few thousand contacts with a simple catalogue, the ceiling is theoretical.
• Nobody owns this internally. Mailchimp’s easier and better supported on the entry plans. A simpler tool someone drives beats a deeper one nobody does.
• You’re not on Shopify. Klaviyo’s advantages are largest where its ecommerce integration is deepest. On other platforms the gap narrows, and some newer Klaviyo features are Shopify-only.
• You mail a small list very heavily. The send allowances are better.

What would change our answer: a catalogue that gets complicated, a subscription line worth protecting, separate Audiences you keep wishing you could segment across, or the first time somebody asks for “everyone who bought the serum on its own and hasn’t reordered in ninety days” and the answer involves a spreadsheet.

So Which One Should You Pick?

The decision rule, as plainly as we can put it: pick Mailchimp if a cheaper plan covers what you’ll realistically build in the next two years, and pick Klaviyo if it doesn’t. At 5,000 contacts they cost the same, so at that size the only question is which one fits how you work.

Mailchimp’s own comparison page arrives somewhere similar from the other direction. Their cost advantage, they write, “becomes particularly evident for smaller teams that may not require advanced eCommerce-specific functionality or deep integrations that Klaviyo specializes in”. A fair description of their customer, and a fair description of who shouldn’t be reading the rest of this page.

For the brands we work with, DTC and recurring-revenue businesses where repeat purchase is the constraint, we’d pick Klaviyo every time. Not because the sending’s better, but because the second and third layers of a lifecycle programme are data problems, and the platform holding the data as customers and events instead of as lists is the one where those layers exist at all. YOCTO LTD is based in Nicosia, Cyprus, and that’s the work we do.

If you’re weighing this up for your own account, our free audit will tell you whether the platform’s really your constraint. Often it isn’t, and we’ll say so.

Frequently Asked Questions

Is Klaviyo more expensive than Mailchimp?

Depends entirely which Mailchimp plan you mean, which is why the question usually gets answered badly. At 5,000 contacts Klaviyo and Mailchimp Standard are both $100 a month. Above that, Standard’s cheaper, by $120 a month at 15,000 contacts and $270 at 50,000. But Mailchimp Premium costs more than Klaviyo at every size we checked, including $465 against $350 at 15,000 contacts. All figures read off both pricing pages on 24 September 2026.

Which is better for ecommerce, Klaviyo or Mailchimp?

Klaviyo, for a structural reason and not a feature list. Klaviyo stores customers and the events attached to them, so segments can be built on what someone bought, which variant, and when they’re due to buy again. Mailchimp organises contacts into Audiences, which serves every kind of business well and a shop with a complicated catalogue less well. For a simple catalogue and a small list, the difference will never reach you.

Why do people say Mailchimp is limiting?

Because capability is tied to plan tier as well as contact count. On the entry plan, automation is capped at four flow steps, which won’t cover a welcome sequence with waits between emails. Predictive segments need Standard or above. The onboarding specialist is Premium only. None of that’s unreasonable pricing, but it does mean you can outgrow your plan without your list growing at all.

Does Mailchimp do anything better than Klaviyo?

Four things. It’s cheaper on Essentials and Standard. Its send allowances are roughly a fifth more generous. Its support on the paid entry plans is 24/7 email and chat, where Klaviyo’s entry support is email. And it’s easier to learn, which is a real advantage when one person owns email among several other jobs.

How hard is it to migrate from Mailchimp to Klaviyo?

The flows take days. Two parts need planning: deciding how your separate Audiences merge into one profile database, and warming your sending reputation over a few weeks before you mail the whole list. Historical engagement data doesn’t fully transfer, so behavioural segments need a rebuild period. Migrations that go badly almost always skipped the warming.

Is Klaviyo worth it for a small store?

Often not, and we’d sooner say so than sell you something. Under a few thousand contacts, with a simple catalogue and no recurring revenue, the things Klaviyo does better are things you won’t use. The case for it starts when repeat purchase becomes the constraint on growth instead of acquisition.

What does Klaviyo cost beyond the email plan?

Its other product lines are priced separately. As of 24 September 2026, Data + Analytics starts around $100 a month and Service and Customer Agent start around $200 a month each, with introductory discounts running on some. The price comparison on this page is Klaviyo’s marketing product against Mailchimp’s marketing plans, which is the fair comparison.

Are the integration counts really that different?

No, and this gets repeated enough to be worth correcting. Klaviyo lists 350+ and Mailchimp lists 300+, on their own sites. What matters isn’t how many logos sit in the directory, it’s what comes through the connection: an order total, or line items and variants and fulfilment events you can segment on years later.

Which platform has better support?

Mailchimp on the entry plans, with 24/7 email and chat where Klaviyo offers email. Mailchimp’s phone support and dedicated onboarding specialist sit on Premium, which costs more than Klaviyo at every size we checked, so if support is your deciding factor, price the plan that actually contains the support you want.

Do I need an agency to run Klaviyo?

No, and plenty of brands run it well without one. The tool’s deeper and less immediately intuitive, which is a fair criticism, and the usual outcome is that a brand either invests the time to learn it or hires someone. The case for help starts when the work stops being sending and starts being data modelling. This argument comes from an agency, so weigh it accordingly.

This is the work we do as a customer retention agency for DTC and subscription brands.
