One method you missed: set up a separate Gmail account with a decent password. Create an email but don't send it - save it in Drafts. Give your password to a trusted person who can go in and read the draft email, and add their reply before saving it again in drafts. That way you can have an email conversation with someone without an email ever being sent.
