As someone who has read plenty of discussions about email security (some of them in this very community), including all kind of stuff (from the company groupie to tinfoil-hat conspiracy theories), I have decided to put too many hours some time to discuss the different threat models for email setups, including the basic most people have, the “secure email provider” one (e.g., Protonmail) and the “I use arch PGP manually BTW”.
Jokes aside, I hope that it provides an overview comprehensive and - I don’t want to say objective, but at least rational - enough so that everyone can draw their own conclusion, while also showing how certain “radical” arguments that I have seen in the past are relatively shortsighted.
The tl;dr is that email is generally not a great solution when talking about security. Depending on your risk profile, using a secure email provider may be the best compromise between realistic security and usability, while if you really have serious security needs, you probably shouldn’t use emails, but if you do then a custom setup is your best choice.

Nice post. My two cents:

Thanks!
I will look into it, there might be a zola option for it. If there is, sure!
That paragraph is in the context of what I call “transparent encryption”, which means E2EE works until the provider is not compromised and the E2EE is effectively broken by delivering malicious software or disclosing the key. E2EE is as resilient as the security of the provider, which is why picking a trusted one is important. Of course, compromising the provider and breaking the E2EE is quite complex.

I suppose, but is there any documented occurrence of that? It seems like a whole stack of what-if scenarios required for that to happen. At that point you should be more concerned with someone beating your password out of you.
