Send limits are a new addition to the Courier app that allow you to manage notification rate limits. This means you can set a maximum limit on the number of notifications you can send over a certain time period. The advantages of using send limits are twofold: you can save money by imposing spending caps on notifications, and you can improve the customer experience of your app by avoiding bombarding users with too many notifications at once.

All apps need a solid, automated notifications system. Whether it’s reminders, updates, or alerts, some notifications can be urgent and time-sensitive, in which case SMS is the most effective communication channel.

Built for developers, Courier is the fastest way to add multi-channel notifications to your web, desktop, or mobile app. With one API call, you can reach your users on any channel – email, SMS, push, chat, and more.

Courier lets you design your notifications once and deliver them to any channel–push notifications, direct messages, SMS, and email–with a single Courier API rather than having to integrate each provider API separately.

Design once, deliver to any channel through one API:

  • Notification Design Studio: Empower every team member to build beautiful notifications.
  • Cross-Channel Engagement Tracking: Get insight on your performance across all channels.
  • Powerful Delivery Rules: Effortlessly route each message to the right notification channel using a robust rules engine. Change channels without touching your code.

The Smartest Way to Design & Deliver Notifications.
