Comparing Klaviyo and Mailchimp means comparing a specialist and a generalist. One was built for e-commerce and never lets go. The other wants to serve everyone, from the nonprofit to the restaurant to the store. Neither is wrong. It all depends on who you are.
And unlike the Klaviyo vs Brevo duel, where the billing model settled things, here both bill by contact and both are US-based. So the match is decided on depth and use case, not on price or data sovereignty.
The real divide: specialist or Swiss army knife
Mailchimp is a generalist. Email, automation, a bit of website, a light CRM, huge brand awareness and a familiar interface. It suits a small business whose marketing needs go beyond the store alone, or anyone who wants a well-known, versatile tool.
Klaviyo is a specialist. It does not try to do everything; it tries to do one thing better than anyone: turn a store's data into revenue. Segmentation based on purchase behaviour, advanced flows, predictive analytics, a tight Shopify integration.
The question is not "which is better" in the abstract. It is "is e-commerce my core business?". If yes, the specialist wins. If your marketing is broader, the generalist holds its own.
Pricing, contact by contact
Both bill by number of contacts. Here are the public reference points for July 2026.
| Contacts | Mailchimp Essentials | Mailchimp Standard | Klaviyo (Email) |
|---|---|---|---|
| Up to 250 | Free (no automation) | Free (no automation) | Free |
| 500 | ~$13/month | ~$20/month | ~$20/month |
| 5,000 | ~$75/month | ~$100/month | ~$100/month |
| 10,000 | by tier | by tier | ~$150/month |
Two takeaways. At entry level, Mailchimp Essentials is a little cheaper, but watch out: multi-step automation only exists on Standard and above, which quickly narrows the gap once you want real scenarios. On the middle tiers the two are close, and Klaviyo offers more e-commerce depth for a comparable price. Note too that both trimmed their free plan to 250 contacts in 2026.
Automation: the gap widens
This is where the specialist pulls ahead. At Mailchimp, serious automation (multi-step journeys, behavioural and predictive segmentation) arrives from the Standard plan. It is decent, but built for general marketing use.
At Klaviyo, automation IS the product. Flows exploit every store signal, segments are built on real purchase behaviour, and the predictive layer steers your sends. For a store that wants a finely conditioned abandoned cart or a post-purchase follow-up driven by customer value, Klaviyo offers levers Mailchimp does not have at the same level.
The match by profile
| Your situation | Our pick | Why |
|---|---|---|
| Shopify store, e-commerce at the core | Klaviyo | Product data, flows and predictive fully exploited |
| Broad marketing (not just the store) | Mailchimp | Versatile generalist, website + light CRM included |
| Beginner who wants simple and familiar | Mailchimp | Familiar interface, affordable entry tier |
| Advanced e-commerce automation | Klaviyo | Flows are its core business |
| Data sovereignty a priority | Neither | Both are US-based: look at Brevo |
Our verdict
If you run a store and e-commerce is your business, Klaviyo is the better tool: its data depth and automation make it a growth engine, provided you use it. Our full Klaviyo review covers what to know before signing.
If your marketing goes beyond the store, or you want a simple, well-known, slightly cheaper tool to start, Mailchimp remains a solid, versatile choice.
And if data sovereignty weighs on your decision, remember this duel is between two US editors: the European alternative is elsewhere, on Brevo's side. For the wider picture of your marketing stack, our guide to AI for small businesses in 2026 sets the scene.
Frequently asked questions
Klaviyo or Mailchimp: which should I choose for an online store?
For a store that wants to exploit its product data and push automation, Klaviyo is the better choice: deeper segmentation, flows and e-commerce integration. Mailchimp remains a very good generalist, simpler and slightly cheaper at entry, suited if your email needs go beyond the store alone or if you are just starting. In short: ambitious e-commerce, Klaviyo; broader, simpler marketing, Mailchimp.
Do Klaviyo and Mailchimp bill the same way?
Yes, both bill by number of contacts, unlike a tool such as Brevo that bills by email volume sent. A large list therefore costs money with either one, even if rarely emailed. At equal contacts, Mailchimp's entry tier is a little cheaper, but Klaviyo offers more e-commerce depth for a similar price on the middle tiers.
How much do Klaviyo and Mailchimp cost in 2026?
At Mailchimp (verified July 2026): Essentials from $13/month and Standard from $20/month for 500 contacts, roughly $75 and $100/month at 5,000 contacts, Premium at $350/month for 10,000. At Klaviyo: free up to 250 contacts, around $20/month for 251-500, $100/month at 5,000 and $150/month at 10,000. Both cut their free plan to 250 contacts in 2026.
Is Mailchimp good for e-commerce?
It does the job, but it is not its specialty. Mailchimp handles email, automation (on paid plans) and even website and light CRM building blocks, making it a marketing Swiss army knife. For pure e-commerce depth, exploiting product data and advanced flows, Klaviyo goes further. The choice depends on whether e-commerce is your core business or one channel among several.
Klaviyo or Mailchimp for data privacy?
Neither is the European option: Klaviyo and Mailchimp are both US-based. On data sovereignty alone they are level, and it is an editor like Brevo (French) that takes the lead. If GDPR and EU hosting are decisive for you, look that way rather than choosing between these two.
