You do respond with your real email, just when you hit send Craigslist changes your email address, so the person receiving it only sees something like:

Zgdjao683hsb@craigslist . Com

It's done automatically for you. This way the persone you are writing to would only have your real email if you choose to type it in your message...but Craigslist blocks that as well so you have to be clever
