IP Sync Alternatives

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.
