Klaviyo Is Eating Mailchimp's Churn

Klaviyo Is Eating Mailchimp's Churn

Inside the same email marketing category, Mailchimp mentions arrive as a swap-out far more often than Klaviyo's do. The gap says which incumbent is actually vulnerable right now.

An ecommerce seller opens their email tool at the start of the month, looks at what they are paying, and this time does not renew. That decision plays out constantly. It just does not play out evenly.

Everyone assumes the email marketing shelf is settled. Mailchimp built the category. Klaviyo built the ecommerce version of it. Neither name has moved in years, so nobody checks who is actually keeping its customers anymore.

The exit door has a name on it

Look at how each tool shows up in live demand and the assumption breaks. When a business mentions Mailchimp, it is asking to leave it far more often than it is asking to start using it. When a business mentions Klaviyo, that almost never happens.

The tool with the bigger install base is not the tool people are staying with.

Roughly one in eight Mailchimp mentions is a request to replace it. For Klaviyo, it is closer to one in thirty. Same category, same kind of buyer.

Share of category mentions that are swap out requests, not new adoption.

Follow that seller through the rest of the story and a pattern appears. They are not comparing five tools and reading reviews. They already know Klaviyo is where ecommerce brands end up, so the shopping phase is over before it starts. What is left is friction.

A few things travel with that exit:

  • It comes from ecommerce. Businesses leaving Mailchimp are disproportionately the ones selling product, not the ones running a newsletter.
  • They already know where they are going. Most of these requests name Klaviyo directly as the destination, not "a better tool."
  • They are migrating, not shopping. The decision is already made. What is missing is a fast way through.

Nobody has built that fast lane yet.

Today the seller does the move by hand, over a weekend, exporting lists and rebuilding flows from memory, and loses momentum in the meantime.

Two straightforward things could close that gap. A one-click importer that carries over flows, tags, and automation history, not just the contact list. Or a fixed-price migration package that guarantees nothing gets lost in the move. Either one is aimed at a seller who already decided to leave and just needs the door held open.

Shelf position that looked permanent two years ago is not permanent now.
