When you send someone an email they automatically are given your email address and all it takes is to hit the Reply button. No typing of address needed. It's not rocket science.
Edit. My bad. Yes you can type in the wrong email address when you 'send' an email. I misunderstood the question.
Tell you what I'll do. I'll send another email. Let you know what happens.
yes this is a stupid question! typed the wrong address 20 times in a row and mind you none of them came back. What about all these other people that never had a reply, wrong address???
