A direct marketing campaign consists of a series of actions planned over time with a single end goal. For example, this might include sending a direct mail piece followed by targeted phone calls, or sending a direct mail piece followed by another mailing to recipients who haven’t responded, except for those who have already replied. It could also involve sending a direct mail piece to people who responded to a print advertisement, followed by phone calls to all contacts. Naturally, those in charge of the campaign will ensure that the people responsible for answering the information calls are trained, as well as that the content of the letters accompanying the materials is prepared.
