[Multichannel Notification Routing]

# Deliver every notification to the right channel

Courier is the logic layer between your app and every notification channel. Define routing rules, set fallback priorities, and honor user preferences all without custom infrastructure.

#### Powerful rules ensure proper routing

Courier allows you to set routing rules such as which channels are preferred over others, which channels should always be delivered, and even conditional statements to define your routing logic.

#### Accessible through the template editor

Drag-and-drop editor to set channel hierarchy, branching logic, and conditionals for complex routing rules.

## Control how notifications are delivered, right from your send request

Courier gives you one API to send notifications over email, SMS, push, in-app, and more. It handles routing, preferences, and personalization so you can focus on your product not message delivery.
