Hello everyone,
I am very new and recently have decided to move away our growing home/work network away from Google and also increase our digital security. I got recommended to try Proton as it is (as I understand) a full suite of feature we would use (be it mail, productivity apps, vpn, authenticator, cloud) but seeing some of the reactions here, I am concerned.
Are there any really grave concerns about Proton or any substantial flaws I should be aware of as a new user? I also got some mixed reviews about unstable gaming sessions (that would be a home disaster for the kids hehe) as it disconnects but I suppose that is a problem of the free limited VPN connecting to free servers.
Thank you in advance for any input.
EDIT: Thank you again very much to all of you for your time and insight <3 I will investigate all the suggestions/experience and slowly work my way to a better workframe. Again - thank you!


For mail, Fastmail is a.much closer replacement to GMail. It’s the only provider I found that supports the same “Send as” feature that GMail has. It works with standard IMAP/JMAP/SMTP. I wish the Android app was separated into separate mail and calendar apps, though.
A problem common to Proton and Fastmail is they don’t feed into the system content providers for calendar and contacts, so that data is isolated from other apps. Fastmail supports CardDav and CalDav, though, so you can use
CALx⁵DAVx⁵ to get that sync.Neither of them integrate Maps with their calendar.
Proton famously has no real offline mode at least for calendar, and the calendar app has no search (last I tried).
Proton Pass doesn’t let you specify a match algorithm so if you have separate logons for different subdomains (foo.example
com.and bar.example.com) it will show you all of them.
As others have mentioned, Proton has been spending time developing apps nobody asked for, like a crypto wallet and AI bot, instead of addressing popular user requests such as the aforementioned “send as” on mail, alternative domain matching in Pass, offline/search/maps in Calendar. They did just recently announce that they’re working on a Linux Drive client, they get credit for that.
Fastmail is way way better
