Email lists are very powerful and profitable. Primarily because if you treat your lists right you will build relationships with them. This aspect overcomes the barriers a buyer feels due to the CONFIDENCE or TRUST factor that all of us have. If you provide quality and useful information or services then it is easier for your list to buy from you. Best Wishes
I couldn't agree more. Giving your users value without any expectation of anything in return will generate sales. It's a simple formula that is used far beyond emailing. Have you ever received flyer, seen a commercial or read something in a newspaper offering something to the effect of "Get this Free Guide...". The motive behind this is simple. The more value, or perceived value, you offer to a prospective client, the more likely they are to opt-in to whatever it is that you're selling.
