Email Marketing Automation

Klaviyo is a B2C CRM and marketing automation platform purpose-built for ecommerce, used day-to-day by email/SMS marketers, retention specialists, and ecommerce operators at DTC brands. It centralizes customer profile data from Shopify, WooCommerce, and other platforms into a unified CDP, then executes personalized campaigns and automated flows across email, SMS, RCS, WhatsApp, and mobile push. Its predictive analytics engine (CLV, churn risk, next-order date) and real-time segmentation are its strongest practitioner differentiators; billing is profile-count-based and can grow expensive as lists scale.
