Privacy

I've been a ProtonMail user for 6 years already but must admit that I'm one of those that is not liking the direction the company is taking and find it worrying, specially now that they plan to launch an office suite that I don't need or want.

I run most of my cloud services self-hosted except email but I'm not fully ready (hardware & software - wise) to admin my own encrypted email server although I don't discard I'll do so in the future. I already know Tuta and it's defo another option but my ideal one should be one that could be used directly with email clients like Thunderbird (I don't mind managing my own GPG keys) so I see Tuta as the retreat option.

So, any ideas for a reliable encrypted email provider other than self-hosting?
