Sometimes poor quality leads or poorly communicated messages may pose problems for marketers as well as consumers as some of such consumers may not be actually interested in the product. So much time and money may be wasted on communicating with such consumers. Sending out direct mails to the addresses to the customers may also irritate some customers. The customers may also have a feeling that their privacy is being invaded and they may not want to disclose any personal information about themselves while being asked to answer questionnaires in direct marketing. Direct marketing has to be convincing enough to win over the trust and belief of the consumers in order to overcome such challenges.
