Hello
Telemarketing is marketing conducted over the telephone. Most telemarketing calls are "cold calls," meaning the recipient of the call has not requested that the telemarketer contact them. Telemarketing is one of the most controversial types of marketing.
The purpose of telemarketing is to make a sale. Sometimes telemarketers have personal information when they call a customer, knowing the person has purchased products similar or related to theirs from other vendors or outlets.
Some older practices of telemarketing inadvertently caused fear. One common type of automated telemarketing program would dial numbers to check for answering machines in order to leave a pre-recorded sales pitch. If a person answered, the program detected a real voice and hung up. Many people were frightened by the unexplained hang-ups, some fearing they were being stalked. It is now illegal for a telemarketer to leave an automated sales pitch on an answering machine.
Thanks
