45. Slowly establish your customer mailing list

^{If you are on eBay trying to carve out a niche, chances are the people that bid on your auctions are in a way interested or connected to your niche of interest, potentially making them long term customers for your other products in the same niche.}

^{How can you make the best use of your mailing list without ending up in the spam box? You have to keep in mind that not every auction will be of interest to everyone on your mailing list so just email them notices for the auctions you think that they will be interested in.}
