About Customer.io

Customer.io is a versatile messaging platform that enables teams to create and send targeted communications based on real-time customer behavior and data. The platform supports email, push notifications, SMS, in-app messages, and webhooks in automated, data-driven workflows.

Unlike traditional email marketing tools, Customer.io is built for behavioral targeting, allowing teams to trigger messages based on specific user actions, attributes, and segments. The visual workflow builder makes it easy to create complex multi-channel campaigns without engineering support.

Customer.io serves both B2B and B2C companies, with particular strength among product-led growth companies that need sophisticated event-driven messaging. The platform's data-first approach and developer-friendly API make it a popular choice for technical teams.
