Review

“The default choice for Shopify stores wanting deep revenue attribution.”

Klaviyo's native Shopify integration surfaces revenue-per-email metrics that generic email tools simply cannot match.

Its predictive analytics (like churn risk and lifetime value) make it feel purpose-built for eCommerce rather than adapted to it.
