Marketers use, as at least one measure of success, the building of long term relationships with customers. They do not want to irritate consumers who might be receptive to hearing from them in other media or who might buy from them directly without being solicited. The e-MPS is a suppression file only and it is not released to a marketer or any other third party who wants to send you a commercial message. Founded in 1917, its members include direct marketers from every business segment as well as the non-profit and electronic and internet marketing sectors. The DMA is not the source of any e-mail marketing lists.
Individual companies are responsible for how they use their own marketing lists.
