Publishing is their business, but they realize they have a valuable commodity in their subscriber list. The brokers have all of the clients, like you, who are the ultimate users of the lists. A list broker can get you virtually any list in the world on the rental market. Most brokers specialize, like we do at InfoLists. InfoLists specializes in business and professional lists, not consumer lists, for clients who sponsor seminars, conferences, and professional training programs.
Some brokers specialize in fund raising lists, lists for investment offers, merchandise lists.
You name it. List brokers typically have no vested interest in the lists they recommend to you. They want to see you use the best, highest response lists, no matter what the source. There are some exceptions to the above, such as some list owners who also take on the list marketing responsibility and go directly to brokers. The price YOU ultimately pay to rent a list is going to be the same whether you work with a broker or an owner, even if there's a manager in between.
