They often say something like "Would you be interested in being told about new developments and products similar to this one?" Those of us that unthinkingly tick yes find ourselves added to a database of potential clients. Another method of collecting the contact information is through a website database system. This is gathered by having an option to receive a weekly newsletter or some such thing. You will be asked for an email address or contact number. This information is added to the database to be used for database marketing. After a certain number of contact details has been accumulated, the database is finalised. It can then be either sold to an interested party or kept for future use by the company that generated it.
Should it be an email address database, it is entered into a system that automatically send s emails out to each address on the list. This email will contain information about the company doing the marketing and about the product they are selling. The email will often include a link to the company's website or product page in order to further punt the product. Database marketing is a much more effective and efficient technique than cold calling. A tactic which involves contacting a random selection of people out of the phone book and attempting to sell them a product or service that they do not need or want to buy. Cold calling is very inefficient and costs a lot in phone bills to keep up.
