Except that:
1) you can still see all the regular e-mail header metadata, so with a
lot of data correlation, you can work out who is doing what and who is
part of which network without decrypting the messages;
2) it sets the NSA's "Has Something To Hide" bit:
<http://www.theregister.co.uk/2016/01/27/nsa_loves_it_when_you_use_pgp/>; and
3) you have to assume that the code and the system you're running it on
haven't been compromised.
The best form of encryption that I ever read about is to use a book.
You need to be able to agree on the book in a secure manner.
Then each word in the message is replaced with a pair of numbers,
corresponding to the page and word offset of the word.
The number data can be appended to a jpg file that is distributed on
social media.
