Identify a problem, present your solutions, and offer to send your free brochure, sample, demo, or an evaluation form or information kit. It allows interested prospects to identify themselves and provides you or your salespeople an opportunity to develop a relationship. The simplest letter mailing includes a one or two page letter and a reply card in an envelope. You can enclose anything else you like, but keep in mind your goal is to get people to ask for more information, not to close the sale immediately. (12/9/11)
