Courier Inbox for web and mobile, a complete notification center

A notification center inside of web and mobile apps is now an expectation. It’s a way to reach specific audiences or users with tailored messages and a way to boost engagement by bringing people back into the app. While Courier has been adding Inbox capabilities over the last couple years, we’re excited to announce a complete set of SDKs that span web and mobile. You can drop in a full-featured inbox to give your users a notification center inside your app that works seamlessly with your existing notification flows.

Controlling notification send limits in Courier

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. Send limits can be applied in a variety of ways, including system-wide notification limits, as well as specific limits for individual users or notification topics. For instance, you can set an overall limit of 200,000 notifications per week. This article will explore the various types of notification rate limits available, explain when send limits are useful, and provide guidance on how to set them up.

Based on invaluable feedback from our customers during the closed beta, we have refined and improved One-Time Send to make it even more efficient and user friendly.

Designing the future of Courier

Today, we are embarking on a significant redesign of Courier's interface consisting of some new things, some old things in new places, and an overall reorganization of the information architecture. Here's a sneak peek 👀 This redesign aims to address the challenges that come with the growth of our platform, where increased size and number of features leads to increased complexity, resulting in a product that may not be as intuitive for new users. We believe that this update will take us closer to a simpler and more organized Courier, setting the stage for more exciting improvements in the future. We hope you like the new look! 💜
