Customer.io

Customer.io is a behavioral email automation platform that uses AI to help SaaS companies and online retailers send highly personalized and timely messages based on user actions and behaviors.

It goes beyond traditional email marketing by enabling businesses to create sophisticated customer journeys triggered by specific events (e.g., sign-up, product view, cart abandonment, feature use).

The “AI optimization” continuously analyzes customer engagement patterns, recommending optimal targeting criteria, drafting personalized email content, and adjusting send times to maximize open rates and conversions.

Key features include powerful behavioral triggers, visual journey mapping for workflow design, advanced segmentation, and AI-driven send-time optimization. By understanding individual customer behavior and leveraging AI for personalization, Customer.io helps businesses nurture leads, onboard users, prevent churn, and drive repeat purchases, increasing engagement and customer lifetime value.
