Firebase Cloud Messaging (FCM) provides a reliable and battery-efficient connection between your server and devices that allows you to deliver and receive messages and notifications on iOS, Android, and the web at no cost.

Easily target messages using predefined segments or create your own, using demographics and behavior. Target messages to devices that have subscribed to specific topics, or get as granular as a single device.

Deliver notification messages immediately, or at a future time in the user's local time zone. Send custom data, and set priorities, sounds, and expiration dates, and track custom conversion events.

Notification messages are fully integrated with Firebase Analytics, giving you access to detailed engagement and conversion tracking. Monitor effectiveness from a single dashboard with no coding required.
