A user received an email due to a commit being pushed upstream and was confused why they got an email. They were not involved in an associated code review. After inspecting with /mail it was due to a Herald rule they configured a year or so back and had forgotten about. The Herald rule observes commits in a repository with an action to email (not subscribe).

Currently the contents of the email don't indicate why they received the email if it's the result of a Herald rule sending an email. Other similar actions do have an indication ("Herald added an auditor: Cat Watch"), though they do not specify which rule. Having something similar for email actions would avoid confusion (ex "Herald rule H20 emailed: you").

Steps to Reproduce

1. Create Personal Herald Rule on Commits
   1. When all of "Diff content" contains "some obscure word only said every 4 blue moons"
   2. Send me an email
2. Create commit with obscure word and push to repository
3. Review email received, note that the rule maker is listed as CC
