How to edit the subject line of a message in Gmail? When clicking the return/down arrow I get a list of options as the following:

  • reply
  • reply to all
  • forward
  • filter messages like this
  • print
  • delete this message
  • report spam
  • show original (that is all the coding)
  • message text garbled?
  • translate message
  • mark as unread

You can't edit an existing message, including subject line. All you can do is change the subject line when responding to a message. (This would spin off a new conversation thread.)

I do know that some third-party email clients will allow you to edit messages. You could always try using one of those, downloading your email, edit the messages you want, then re-upload them (or just use IMAP), but you'd probably end up with two separate messages and such things are beyond the ken of this site.
