What is Klaviyo?
Klaviyo is a B2C customer platform that combines customer profiles, event data, email, SMS, mobile push, automation, segmentation, analytics, service tools, and AI. Ecommerce brands use it to turn store behavior and customer history into personalized lifecycle campaigns.

Our Take
Klaviyo delivers the most value when a brand uses its data depth, not when it is treated as a newsletter sender. Build a small number of measurable lifecycle programs first, then expand segmentation and channels as revenue justifies the added complexity.
