@v_raton @vmstan @cadusilva @protonprivacy I would suggest staying away from companies that provide "encrypted email". There's only one company that offers full encryption of everything (unlike Proton) which is Tuta. But you're locked into using their clients as they don't use PGP. You can decide whether you care about that.
I personally use Migadu. They're much smaller and require you to own a domain, but their support is excellent and their cheapest plan is very affordable.
Then again, almost any email provider is a step up from Proton.
