About Courier
Courier provides a comprehensive notification infrastructure for development teams. It abstracts the APIs of multiple providers (e.g., SendGrid for email, Twilio for SMS, FCM for push) into a single, unified interface. The platform includes a visual template editor that allows non-developers to create and manage notification content across all channels. Key features include intelligent routing to define notification sequences and failover logic, real-time logging for debugging, and analytics to track performance. This allows engineering teams to offload notification logic and empower product teams to control the user communication experience.
