When you’re building a web application, there’s an immediate decision to make about how to handle Users and Authentication.

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.

We added the ability to customize the message icon for inbox messages. That means you can set a different icon for each type of notification that you send. To do this, Message Icons needs to be enabled in your brand’s in-app settings (they should be by default). Then you can add an icon to your notification template.

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. Let’s take a moment to talk about what that means for you as a developer. You need to: Realistically, building this feature from scratch can be time-consuming and complicated.

The ability to unify all notification metrics and logs across channels and providers into an easy-to-use dashboard is a core advantage of Courier’s notification infrastructure. However, with product notifications so critical to the entire application experience, it’s important to connect that data back to central cloud observability platforms that look across the entire stack.

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.

  • 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.
