Courier

Courier is a comprehensive platform designed for developers and product teams to manage all customer notifications from a single place. Instead of juggling separate services for email, push, SMS, Slack, and in-app messages, you can use one API and a unified system to reach users on any channel.

Developers can get started in minutes with SDKs for Node.js, Python, Ruby, Go, and more. The platform includes pre-built, customizable components for adding a complete in-app notification center to any web or mobile app. For product managers and marketers, the drag-and-drop design studio allows for creating and updating beautiful notification templates without writing any code.

Beyond sending messages, you can build sophisticated workflows using the visual automation builder. This makes it easy to set up features like:

• Digests: Combine multiple updates into a single summary.
• Batching: Group and schedule notifications to avoid overwhelming users.
• User Preferences: Give users total control over how and when they receive alerts, ensuring GDPR and CCPA compliance.
• Analytics: Track engagement and view detailed logs across all channels to optimize your communication strategy.
