Direct marketing professionals have developed targeted e-mail lists that consist of people who have agreed to receive commercial e-mail messages specific to particular industries. You can rent lists specific to your industry to create a foundation or augment your existing prospect list. You may want to rent a small list at first and use that as a test to determine the quality of the prospects. Also, remember that this is a form of direct marketing, and you cannot necessarily expect the same kind of response that you might from your own, vetted, self-enrolled customer and prospect base. Still, if you track web traffic statistics from these campaigns you may find a new untapped market. Using your log files and web traffic wisely can save you time and money!
