The mods will no doubt move this to the classfieds section of the forum (as that's where it should be).
You are not supposed to put email addresses on your adverts. All trades/sales have to be done on your thread on the forum. Only after a sale is agreed and private details are exchanged does this change and it's usually done via PM (private message on this forum) rather than email.
A quick read of the forum rules might be a good idea.
