How Courier works
Courier is the easiest way to integrate user notifications to your application. It works by providing a rich visual editor and robust orchestration engine to craft beautiful notifications that do not require engineering time to build or maintain. Our powerful REST API makes sending those notifications to one or more communication channels via a single API request effortless.
Get more out of Courier with Segment
Connecting Segment to Courier enables you to send user notifications without shipping any code. Anyone can easily pick an event, add one or more communication channels, and use our Notification Design Studio to start delivering new notifications.
Installing Courier with Segment automatically populates recipient profiles for use in sending to any of our existing integrations, including email, SMS, in-app push, messaging apps, and more. Once Courier’s Segment Destination is installed, you can send notifications in minutes by simply mapping incoming Segment-powered events to the correct Notifications in Courier.
