Quizplus · Accepted Answer

List brokers serve both the list owner and marketer by facilitating the rental or sale of targeted lists of potential customers. They assist list owners in finding potential customers and assist marketers in finding the right audience for their products or services. Publishers primarily serve list owners by creating and distributing content to their subscribers, inquirers are individuals who have expressed interest in a product or service but may not yet be on a particular list, subscribers are individuals who have opted-in to a particular list, and purchasers have already made a purchase from a marketer.
