permission marketing

Permission marketing is an approach to selling goods and services in which a prospect explicitly agrees in advance to receive marketing information. opt-in e-mail, where Internet users sign up in advance for information about certain product categories, is a good example of permission marketing. Advocates of permission marketing argue that it is effective because the prospect is more receptive to a message that has been requested in advance and more cost-efficient because the prospect is already identified and targetted. In a world of information overload, automated telemarketing, and spam, most people welcome the idea of permission marketing.
