Do both.

I used to embed tags in emails, e.g., will-reply:2d and silly stuff like that for two reasons:

1) Keyboard macros could expand it into human-readable text (but leave the tag) and

2) The email client I used at the time made it easy to hang functionality off of email content so I could automate stuff like issue and time tracking etc. based on email tags.
