Email & Retention

Klaviyo

The dominant email marketing platform for Shopify ecommerce. Handles campaigns, flows, segmentation, and SMS — usually 20-35% of a mature store's revenue.

Klaviyo is the dominant email marketing platform in the Shopify ecommerce ecosystem. It handles campaigns (one-time sends), flows (automated sequences triggered by behavior), segmentation, and SMS in one integrated tool.

Why Klaviyo dominates: deep native Shopify integration (event tracking, order data, product feeds all sync automatically), mature automation logic, and a segmentation engine that lets you build audiences on any combination of behavior and property. Competitors (Omnisend, Drip, MailerLite) are catchable on price, but Klaviyo's data depth keeps it central for any store serious about retention.

A well-run Klaviyo implementation typically produces 20-35% of total store revenue from flows and campaigns combined — at effectively zero CAC, because the traffic is owned.
