Another form of online marketing is affiliate marketing. This involves the art of selling other peoples’ products or services or even information for that matter. Affiliate marketers come in all shapes and sizes and the reason why it’s so attractive to so many people is because you don’t need to setup many of the business systems or even have any employees to actually make money online in this fashion.
Companies considering the use of an email marketing program must make sure that their program does not violate spam laws such as the United States' Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN-SPAM), the European Privacy and Electronic Communications Regulations 2003, or their Internet service provider's acceptable use policy.
Marketing is based on thinking about the business in terms of customer needs and their satisfaction. Marketing differs from selling because (in the words of Harvard Business School's retired professor of marketing Theodore C. Levitt) "Selling concerns itself with the tricks and techniques of getting people to exchange their cash for your product. It is not concerned with the values that the exchange is all about. And it does not, as marketing invariable does, view the entire business process as consisting of a tightly integrated effort to discover, create, arouse and satisfy customer needs." In other words, marketing has less to do with getting customers to pay for your product as it does developing a demand for that product and fulfilling the customer's needs.
A common example of permission marketing is a newsletter sent to an advertising firm's customers. Such newsletters inform customers of upcoming events or promotions, or new products. In this type of advertising, a company that wants to send a newsletter to their customers may ask them at the point of purchase if they would like to receive the newsletter.
