Customer.io is a versatile marketing automation tool for sending relevant messages based on behavior across web and mobile products.

Impersonal messages lead to bad experiences. That’s why we use real-time data to help you deliver the right message, exactly when it’s needed — like sending an event reminder over SMS or the perfect onboarding email.

Our robust platform enables you to:

• Automate your product messaging, with the ability to build, test, and send messages from one platform.
• Create and manage newsletters, transactional messages, and behavioral messages
• Do more with your behavior and data -- connect our powerful segmentation and automation engine with other apps to drive user behavior and save time.
