Mailchimp vs Klaviyo

One was built to send a beautiful newsletter to a list. The other was built to print money for ecommerce brands. The right answer depends entirely on what you sell.

The 30-second verdict

Pick Klaviyo if you sell things online. The Shopify integration is best in class, abandoned-cart flows convert, and revenue attribution is built in so you can see the dollar value of every flow. Pick Mailchimp if you do not sell things online it is friendlier to start, generous on the free tier, and perfectly fine for newsletters and the kind of basic automation most service businesses need.

Winner: Klaviyo for ecommerce. Mailchimp for everything else under 10,000 contacts.

Side by side.

Choose Mailchimp if
  • You do not sell physical products online
  • You want the friendliest place to send your first newsletter
  • The free tier might carry you for a year
  • Your team is not full-time marketers
  • You like the templates more than you should admit
Choose Klaviyo if
  • You sell on Shopify or WooCommerce and care about revenue per email
  • You want abandoned-cart flows that actually convert
  • You want SMS in the same tool as email
  • You think in segments, not lists
  • You will outgrow Mailchimp inside the first year
Bottom line

If you sell online, just start with Klaviyo. The migration cost from Mailchimp to Klaviyo six months in is the most predictable mistake we see ecommerce brands make. If you do not sell online, Mailchimp is fine and probably free for longer than you think.
