It does not matter to much for me. My threat model is not so high and if i
like to do so i can encrypt my mail and run it through codegroup.

And with De-Mail people can put an OpenPGP pub key in their directory,
so that people can get the pub key from there, regardless of which
De-Mail service provider they use.

P.S. We should get back on topic from the OP, on how to send securely
OpenPGP letters / postcards via regular mail.

If one googles for the string "encrypted postcards" there are many
links shown, from people who did that in the early 20th century. :-)

Best regards
