When you receive an inquiry from a buyer who has seen your Trade Lead at The Trade Lead Zone his email address is placed in the "from" of the email message.  All you have to do is hit "reply" to respond to the inquiry.

All your inquiries are also stored in your "my communications" section of your Trade Lead Zone Account.  This can be reached by pressing the "My Account" button at the top of The Trade Lead Zone home page.  There you can also contact the person sending the Trade Lead inquiry.
