About a year or two ago ProtonMail suspended my account for no reason after being a paying customer for about 5+ years. Their only support contact method at that time was email. 😉 Anyway, they gave me some bullshit reasons (lies) as to why the account was suspend but did reactivate the account after contacting them by an alternate email address. Anyway, I dump them like a hot potato and I'm now using tuta.com. Bottom line ProtonMail does value their paying customers. Sure will be nice to see the need for email to become absolute zero.
