The incoming email annoyed you to say the least. You have written your proposed response, controverted all of the points, dealt with all the inaccuracies, this email will really show them who is boss, press send and go home, what is more put your out of office on that you are not back now until tomorrow. Is that the right response? You may feel better but it is often not the right response. My preference would be that, having written it, save it to drafts and read the incoming email and your response again in the morning.
