How does direct marketing compared to mass marketing?

The difference between Direct Marketing and mass marketing is as follows:

Direct marketing primarily aims at commerce to a personal place-able by name, address and buying behavior. On the other hand, mass selling aims at broad level of homogeneous teams sharing common demographic characteristics.
Direct market has management over the merchandise all the method through final delivery and will involve things such as door step delivery or distribution of merchandise . In Mass selling it’s unfeasible because the merchandise enter the various channels.
In the Mass selling concept advertising is employed to create image, awareness and loyalty and it’s to be repetitive in nature. The impact of buying action is delayed. In the direct marketing the advertisement is geared towards people and therefore the impact is straight away celebrated by method of obtaining associate order. In Mass selling the patron has direct contact with the merchandise and merchant and has direct resources  if required. However In direct marketing consumers feel a lot more at risk because the product is bought unseen or untouched and recourse appears distant.
