Email is an effective and cost-efficient mechanism to communicate with prospects and customers. The cost per contact with email can be a fraction of the cost versus other targeted channels such as direct mail. Purchasing email lists, however, has a number of drawbacks. Typically, purchased email lists don’t work. Email marketing is most effective where the user has a perceived relationship with the company. People simply view unsolicited emails as spam. There is significant fear about opening and clicking on emails that aren’t from a company or brand people perceive having a relationship with, or have actually provided their email address.
