Courier
One API for all your product's notifications.
Overview
Courier is a notification infrastructure platform that allows developers to manage all their product-triggered communications in one place. While its primary focus is on channels like email, push, and SMS, it uses an event-driven model. It can be triggered by webhooks (via integrations) and can send webhooks as a notification channel, allowing it to act as a transformation and routing layer for events.
✨ Key Features

- Visual template builder
- User preferences management
- Notification routing and logic engine
- Logs and analytics
- Webhook channel for delivery
🎯 Key Differentiators

Unique Value: Saves engineering teams hundreds of hours by providing a single API and management layer for all transactional notifications, including webhooks.
