Mail Notifr

An Open Source Gmail Notifier for macOS (formerly Gmail Notifr)

Mail Notifr sunset on March 8th, 2024.

As this app needs to access Gmail restricted APIs, it’s required to complete a CASA security assessment, which is a progress I could NOT get through.

I’ve decided to make the end of its service. Sorry, and thank you.
