Editors are timid, forgetful creatures (likely due to a childhood full of reading and seclusion). This means they'll forget you sent them your manuscript, or perhaps have it slip their minds they should be working on yours instead of relaxing on the couch watching television. So once you turn in your manuscript, send them emails at least once a day. See how the progress is going. Let them know how excited you are to get it back. If they ever stop responding, up your game, sending both emails and calling on the phone if you happen to have their number. All this attention will let them know how important they are to you, leaving them feeling flattered and eager to work on your book.
