One of the largest holes in encrypted communication is still the fact that the vast majority of email is still neither digitally signed, nor encrypted. And even if they are, the usual schemes do not encrypt the subject line.
I wish there was something like Let's encrypt but for email. Just make it trivial to sign and encrypt your mail. Also, mail clients should give a huge warning for unencrypted and/or unsigned mail, just like browsers do with web sites. Right now, at least on Outlook for macOS, you only get a happy green padlock on signed email, if you ever receive one.
