Built for developers, Courier is the fastest way to add multi-channel product notifications to your web or mobile app. Make developers' lives easier with a suite of features like automations, preferences management, audit logs, and white-labeling.
I'm biased, but I've been building a lot of apps with Courier lately and it's a joy to work with. I like how the system is designed, the REST API is great and the SDKs (React, iOS and Android) are really well executed.
This is really cool. I've tried Courier out but haven't had a chance to use it yet. Why build out notifications yourself instead of your core product!?
