After I moved away from Google services as much as I could (https://www.mac-vicar.eu//posts/2020-10-20-migrating-away-go...), and after some years on mailbox.org, which I did not enjoy, I ended moving to Infomaniak.
The experience has been nothing but awesome. I love the Android clients (mail, calendar sync) and I am also using their AI services for light tasks. Management UI is a bit confusing but not the worst I deal with.
Glad to see this move. I am a fan!.
