I too scripted a Google Script to run daily, with sending me a reminder or question; & Gmail tags that outgoing mail as a specific label; script pulls that labeled mail every day, archives it, appends the contents to a Google Doc.

Thank you.

Once for making this.

Second time for making it genuinely easy to use and setup myself.

very nice @maccaw

unlike "Diary Email" your readme makes it very clear where the emails go, and since I'd host it I know no-one would read it.

err.. You know that emails transit un clear text, right?

Not if the server admins of both sides are even remotely competent. A good "email server" will at least allow, if not enforce encryption client<->server and (if supported by the other party) server<->recipients_server.

I've enforced TLS when sending email for about a year now with few problems
