Telemarketing growth – A good thing?

This day and age telemarketing is a growth industry with telemarketing services ranging from banking and the financial sector right through to products and services. Telemarketing can be a double edged sword though. When done correctly it offers the best way to get through straight to the customer but can also be a thorn in the side for the consumer when they get inundated with calls from particularly persistent telemarketing agencies.
The best agencies employ highly trained professional staff with a good knowledge of the products and services they are promoting. They also tend to have a good staff retention rate which is not only good for the client but also good for the consumer with staff having a good knowledge of the products they are promoting. Therefore I would say growth in the industry is a good thing but only when the job is carried out professionally.
