Courier

Courier supports a wide range of communication channels including email, SMS, mobile push notifications, Slack, Microsoft Teams, and WhatsApp. This allows developers to manage diverse messaging requirements through a single interface rather than maintaining separate integrations for each individual provider.

Courier is designed for backend engineers, product developers, and customer experience teams responsible for managing user engagement and system alerts. It is particularly useful for teams needing to scale notification delivery without building custom infrastructure for every messaging platform.

To implement Courier, you must have existing accounts with your chosen messaging providers, such as SendGrid for email or Twilio for SMS. You then integrate the Courier platform to act as the central routing layer for your outgoing messages.
