Klaviyo vs Mailchimp: Which One Should You Choose?

Everyone asks Klaviyo or Mailchimp like there's one answer. There isn't. Here's the honest call by business type, where each wins, what they cost, and when it's worth switching.

Klaviyo vs Mailchimp is one of the most common questions I get from business owners, and it’s almost always asked as if there’s a single right answer. There isn’t. The honest answer depends on one thing above all: whether you sell products online or not.

Both are good tools. They’re just built for different jobs. Klaviyo is an ecommerce revenue engine that happens to send email; Mailchimp is a friendly all-rounder that happens to do ecommerce. Pick the one built for your situation and either can earn its fee. Pick the wrong one and you’ll either overpay for power you never use, or hit a wall the day you try to grow.

I run both across client accounts, so I’m not on either payroll. This is the comparison I’d give a friend: the short answer by business type, where each genuinely wins, what they cost, and when it’s worth switching. If you want the wider picture first, start with our email marketing guide.

The short version

The right email platform is the one that earns its keep for your business.

  • It comes down to ecommerce, or not. Selling products online points to Klaviyo; sending newsletters points to Mailchimp.
  • Klaviyo is built to make stores money. Deep Shopify data, behaviour-based flows, and revenue you can actually see per email.
  • Mailchimp is simpler and cheaper to start. Great for basic campaigns and non-ecommerce, weaker once you need serious automation.
  • Price scales differently. Klaviyo climbs with your list and can get steep; Mailchimp is gentle early, then limiting.
  • Switching has a cost. Migrate to break a real ceiling, not because a blog told you one is “better”.

The short answer, by business type

If you want the whole thing in three lines, here it is. Everything below is just the detail behind these.

You run an online store: Klaviyo, almost always. You send newsletters or you’re a service business: Mailchimp, or something simpler. You’re tiny and just starting: use a free tier and don’t overthink it.

The reason the Klaviyo vs Mailchimp choice splits so cleanly is that Klaviyo’s whole advantage is ecommerce data. If you don’t have a store feeding it, most of what you’re paying for sits idle.

Which one fits you?

Pick the description that sounds most like your business and I’ll give you the honest call.

Which sounds like you?

Go Klaviyo
Klaviyo, almost always. The Shopify integration and behaviour-based flows are built to turn browsing into revenue, and you see the money each email makes. This is exactly what it’s for.
Lean Mailchimp
Usually Mailchimp, or something simpler. Unless you’re running complex, behaviour-triggered sequences, Klaviyo’s ecommerce power goes to waste and you pay for features you never touch.
Mailchimp
Mailchimp, comfortably. For regular campaigns to a list, it’s cheaper, friendlier and more than enough. Klaviyo would be an expensive overkill here.
Either, start free
Don’t overthink it. On a small list, both free tiers are fine. Pick for where you’re heading: Klaviyo if a store’s on the way, Mailchimp if not.

Where Klaviyo wins

Klaviyo earns its reputation with online stores, and it’s not close. If you sell products, this is where the gap shows.

Ecommerce flows with real data behind them. Abandoned cart, browse abandonment, post-purchase, winback, all triggered by what someone actually did and what they looked at. That product data is the whole point, and it’s what our Shopify email flows guide leans on.

Revenue you can see. Klaviyo reports the money each campaign and flow brings in, not just opens and clicks. That changes how you make decisions, because you’re optimising for dollars instead of vanity metrics.

Segmentation that goes deep. Slice your list by purchase history, spend, behaviour and predicted value, then send accordingly. On a store, that precision is where a lot of the extra revenue hides.

Where Mailchimp wins

Mailchimp gets unfairly dismissed by the ecommerce crowd. For the right business it’s the smarter, cheaper choice, and there are plenty of those.

Simplicity. It’s friendlier, quicker to learn, and less likely to leave you staring at a flow builder wondering where the afternoon went. For a small team, that matters more than raw power.

Cost at small scale. If you’re sending straightforward campaigns to a modest list, Mailchimp is easier on the wallet and does the job. And if you’re mostly sending campaigns, when you send them matters as much as the tool you use.

All-rounder basics. Landing pages, simple automations, a light CRM. If email is one of several things you dabble in rather than a core revenue channel, that breadth is genuinely handy.

Klaviyo vs Mailchimp, side by side

The honest Klaviyo vs Mailchimp head-to-head. The Klaviyo column is highlighted because most people asking this question run a store, but read the Mailchimp column properly, because for a lot of businesses it’s the right one.

  Mailchimp Klaviyo

From the studio
I build on Klaviyo for pretty much every store we run, so I’m a fan. But I’ve also talked plenty of small service businesses out of it. Someone signs up because they read it’s the best, then uses a fraction of it to send a monthly update, and pays for the privilege. The best platform isn’t the most powerful one, it’s the one that matches what you actually do. For a lot of businesses, that’s the boring, cheaper choice.

What Klaviyo and Mailchimp actually cost

Cost is where the Klaviyo vs Mailchimp gap feels most real. Pricing changes often, so treat this as the shape of it, not a quote. Both start free, and both get pricier as you grow, just along different lines.

Mailchimp charges by contacts and is gentle at the start, which is why so many businesses begin there. The catch is the genuinely useful features sit in the higher tiers, so the real cost creeps up as you need proper segmentation and automation.

Klaviyo charges by the profiles you store and send to, and it can climb fast on a big list. The fairer way to judge it is against the revenue it drives, since it shows you the money each flow makes. Expensive is relative when you can see the return, which is exactly why Klaviyo pricing panics people less once the flows are running.

When it’s worth switching

Most switches go one direction, for one reason. Here’s when the hassle pays off, and when it doesn’t.

Mailchimp to Klaviyo: the classic move. You’ve outgrown Mailchimp’s ecommerce limits, your flows are leaving money on the table, and the extra revenue will dwarf the higher fee. That switch pays for itself.

Klaviyo to something simpler: the one nobody talks about. If you’re on Klaviyo sending the odd newsletter to a modest list, you’re paying for an engine you never rev. There’s no shame in downgrading; it’s often the smarter, cheaper call.

Don’t switch just to switch. Migrating lists, flows and deliverability history is real work, and a botched move can dent your inbox placement. Change platforms to break a genuine ceiling, not because of a comparison post, this one included.

What actually happens after a migration

The Mailchimp to Klaviyo move is one I’ve run many times, so let me tell you what actually happens, because it’s rarely the part people expect.

The lift almost never comes from the campaigns, the one-off sends. It comes from the flows: the welcome series, the abandoned-cart and browse-abandonment sequences, the post-purchase follow-ups that run automatically in the background. Mailchimp can do a version of these; Klaviyo does them with the store’s data behind them, so they’re sharper and they convert. The owners who are thrilled six weeks after a migration are the ones who let us rebuild the flows properly, not the ones who just re-sent the old newsletter with a new logo. The platform is just the enabler; the real work is the flows.

How we know this: We run both Klaviyo and Mailchimp across client accounts, and the pattern is consistent. For stores, the revenue almost always sits in the automated flows, and Klaviyo’s store integration makes those flows measurably better. For simple newsletter senders, the extra power goes unused and the cheaper tool wins. We pick per client, not per trend. Last verified September 2026.

Frequently asked questions

Is Klaviyo or Mailchimp better?

Neither is better in the abstract; it depends on your business. For online stores, Klaviyo usually wins on ecommerce flows and revenue tracking. For newsletters and non-ecommerce, Mailchimp is simpler, cheaper and often more than enough. Match the tool to what you actually do.

Is Klaviyo worth the higher price?

For an ecommerce store, usually yes, because the revenue comes from its automated flows and it shows you the money each one makes. For a small newsletter, probably not, since you’d pay for power you won’t use. Judge it against the revenue it drives, not the sticker price.

Can I switch from Mailchimp to Klaviyo?

Yes, and it’s the most common move for growing stores. You migrate your lists, rebuild your flows and warm up deliverability. The gain almost always comes from rebuilding the automations properly, not from re-sending the same campaigns, so treat the migration as a chance to redo the flows.

Is Mailchimp good for ecommerce?

It can handle basic ecommerce, but it isn’t its strength. For a store that wants serious abandoned-cart, browse and post-purchase flows tied to product data, Klaviyo is built for that job. If ecommerce is central to your business, you’ll likely outgrow Mailchimp.

How much do Klaviyo and Mailchimp cost?

Both have free tiers and both scale up as you grow. Mailchimp charges by contacts and is cheaper early, with key features in higher tiers. Klaviyo charges by profiles and can climb faster, but ties to the revenue it reports. Pricing changes often, so check current plans before deciding.

Which is easier to use, Klaviyo or Mailchimp?

Mailchimp is generally friendlier and quicker to learn, which suits beginners and simple campaigns. Klaviyo is more powerful with a steeper curve, especially for its flows and segmentation. The extra complexity pays off when you actually need the depth, and gets in the way when you don’t.
