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 switched email providers a few times, but I bought a custom domain and use that as my email address. Which makes switching providers easy. I'm sure I don't need to mention that in a Privacy community, but figured I would anyway.
I went from an @gmail, to @proton (then bought the domain), then switched to Fastmail with same domain.
