Ratings and reviews

I have over 25 years experience in messaging from setting up complete enterprise environments to support and troubleshooting. This client is ok. It's missing some common email client options like calendaring for example. A complete email package for business users needs calendaring. Relying on the built in Android and Apple calendar is not the same. Encrypted message support would be a great option as well. Over all, it works.

long time google workspace user and I like it enough to migrate all my email to it. I'm travelling abroad at the moment and everything is working perfectly on my Synology on the other side of the world on phone and desktop in chrome browser, 😊 some feedback here is a bit out of date with current 2026 feature set!

One of the reasons why I am put off I think using this app is due to the lack of a search folder option when moving an email to a folder. One needs to scroll up and down to find the right one which kills the productivity. Also, I suggest you check the nine app for android, they have that plus tabs to allow selecting frequently used or favourite folders. TIA
