Disadvantages of the direct marketing:
May be seen as competing with existing intermedaies: may upset marketing intermediaries as sales through the direct marketing may be taking sales away from them. In effect, you may end up competing with own customers, that is, the intermediaries.
May be seen as instructive by the customers: especially a problem for door -to - door and marketing.
Costs: initial customer acquisition costs are high - high cost per thousand reached, and database development can be expensive.
