Ecommerce stores using Klaviyo
340,000 Shopify and WooCommerce stores in our database run Klaviyo. Updated August 22, 2026.
Klaviyo adoption across Shopify and WooCommerce
Klaviyo is the most widely installed email and retention tool among the stores we track. 340,000 stores currently run it, which is 8.3% of our database.
Adoption alone says little. What matters for outreach is when a store installed it, because the weeks after an install are when flows get built or quietly do not.

Why brands using Klaviyo are a distinct segment
A store that just installed Klaviyo has made a decision and has not yet seen a return on it. That is a different conversation from a store that has run it for two years and has flows in place.
Retention agencies get the strongest angle here, and it is time bound: offer the first flow while the tool is still new. Watch new installs as they happen in stores installing an email tool.
How we detect it
Tool detection runs on the storefront itself during the weekly scrape. Every record carries the date it was last confirmed, so you can tell a fresh install from a long standing one.
Next: build a segment from this data or browse the signal catalogue.
