Klaviyo
The #1 email and SMS marketing platform for e-commerce revenue growth
What is Klaviyo?
Klaviyo is the de facto standard for e-commerce email and SMS marketing. Used by over 150,000 businesses, it was built from the ground up to connect with e-commerce platforms at the data level — syncing every browse event, purchase, cart action, and customer attribute in real time.
That data depth enables Klaviyo's most powerful feature: predictive analytics. It calculates predicted customer lifetime value, churn risk, and the optimal send time for each individual subscriber. Flows (automated sequences) cover every e-commerce scenario: abandoned cart, browse abandonment, post-purchase, win-back, VIP upgrade, and replenishment reminders — all triggered by real-time behavior. The AI-powered product recommendations engine inserts personalized items into emails based on purchase history. For Shopify stores especially, Klaviyo's native integration is unmatched. Pricing scales with contact count, which can become expensive for large lists.
