Again, Signal is touted as better than PGP.Why?Look at this problem
with signal. Looks really serious.

to screw up encrypted email in a way that exposes the cleartext.  
Encrypted email is fundamentally unsafe as it currently exists. 
It’s really hard to screw up some of the new E2E encrypted
messengers.  Sure, if your method for secure communications is
dropping stego’d memes with encrypted payloads on imgur, then simple
tools like Signal and WhatsApp won’t do.  But if you’re trying to
securely communicate like a normal person who is not pretending to be
Mister Robot, then PGP for email is one of the least adopted, least
safe ways to do so and Signal/iMessage/WhatsApp are decent solutions.

Depends on your threat model.  For mine, reliably and easily
encrypting email is almost absurdly simple:

1) Use PGP
2) Don't send secrets to people I don't trust to keep them.

Anyway, 99% of my PGP use is for the opposite of secrecy: I sign my
emails so that (if you care enough to install PGP) you can be highly
assured that they're from me.
