This lesson covered chapter 7.
Permission marketing is when permission is required by the customer to either send or not send advertisements (usually via email). Opt-out means that the customer did not refuse to receive messages, but did not request them either. Opt-in is when the customer specifically requests to be contacted. It is an important concept to marketers because often times, the opt-in/opt-out of an individual is a clue to their level of interest in the marketed product. ime does not need to to be wasted on those who do no want to be contacted.
