I moved from Proton to Fastmail (and Mullvad for VPN).

I was a a founding paying member of Proton Mail. I loved them and evangelised them for years. But after a decade, the quality of the offering, especially the mail and calendar, is almost a joke, and the company seems very distracted chasing the next big thing (the half baked password manager being one).

Comparing Fastmail’s UI and feature set with Proton, you quickly realise they are leagues apart.

And no Fastmail doesn’t provide e2e encryption. For that I use Signal, and for the few occasions where I need e2e encryption in email, I use PGP.

My only wish is that there was more client support for JMAP protocol. Even thunderbird doesn’t support it, and I can’t go back to IMAP because I like labels. Thankfully Fastmail’s own web interface is so good it is not a big issue.
