Luckily my main provider (and soon only one) for secured email is Msgsafe.
The principle of using encrypted mails/messengers is to hide from everyone, government and other intelligence organizations included.
If not, and just required to have a safe email provider, I would just use Gmail which is secure enough against normal people who don't have the authority to force my emails to be disclosed.
I use Msgsafe because I don't want any law enforcement agency to read them.
After ditching Protonmail, now it is Tutanota turn. Those two are bullshitters, such a shame claiming to offer full privacy while they give access/backdoors to authorities...
Having anonymity and privacy in our time becomes an almost impossible task for the non-initiate...
As I often said in various forums, if you don't do activist/criminal/border-illegal stuff, dont bother deploying anonymity/privacy tools, too much an hassle. Just enjoy internet on Windows, common services are safe enough.
