FWIW I would never write an email like that to you. I would begin by thanking you for the work, then asking my question, then probably closing the email because I have successfully rubber-ducked my question, then days later rewriting the draft again with a better question, and finally ending the email with "If you ever get a chance, I'd appreciate you pointing me in the right direction" or somesuch.
