I've cancelled my subscription yesterday, conveniently it was about to renew at the end of the week, so I have a few days to migrate from Proton, here's what I'm thinking of, but I'd love to hear what other people are switching to
I've been using mailbox.org for a few years now and I love it.
the web client is good, and it was easy to set up on my phone alongside my other accounts.
it costs money (something like β¬3/year), but it's worth it.
plus, it's still relatively new, so if you suffer from Generic White Guy Nameβ’ like I do, you can finally have a username/email address that's not full of numbers.
