Can age encrypt email messages instead of just files?

[Fastidious]

Use age with -a option on a file with the text of your email, and use the resultant file content as the email itself. Easily scripted if using mutt or similar email client.

Please take a look at the spec at https://age-encryption.org/v1 and see the section "Out of scope"

Anything about emails (which are a fundamentally unsecurable medium)

Though, you can encrypt text and put the encrypted file in an E-Mail, but this is nothing like S/MIME or GPG encrypted E-Mails.
