Hack Of The Night : How to avoid sending an email too early

Like many people, when drafting an email, I used to always put in who I'm sending it to first, then work my way down and write the message.  Thanks to this hack, I'm never going to do that again. 

It sucks when you're drafting and email and you accidentally send it before you're ready to.  Then you have to send a follow up email (looking like an idiot) to explain what happened, and then finish your message.  Well this makes total sense, and I now do this all the time.
