I'm tidying my Glitch mailbox today. I have to do this periodically because I like to save the messages people send. Once my Glitch mailbox has more than 50 messages, though, I can't get to the older messages. So I take screen shots of the messages I want to keep (which turns out to be most of them) and then delete them from my Glitch mailbox. This is much easier to do now that I can read my Glitch mail from my home page rather than having to go to a mailbox in-game.
Do you like to save Glitch mail? If so, do you have a method for saving it offline?
