Klaviyo
B2C CRM for email and SMS with predictive analytics and AI send optimization
About
Klaviyo is the dominant email/SMS platform for e-commerce, built around a customer data platform that syncs purchase history, browse behavior, and order value (especially deep with Shopify) to power segmentation and lifecycle flows. Its AI focuses on predictive analytics — customer lifetime value, churn risk, next order date — plus smart send time and AI-tested subject lines, rather than email body copywriting. Pricing: free up to 250 active profiles, Email from $20/month, Email+SMS from $35/month, but the February 2025 shift to active-profile billing raised costs for many businesses and each channel is billed separately. Reviewers note strong ROI when the predictive features are fully used, and poor value when they are not.
