You probably hear the saying a lot, you know, "the money is in the list." Almost every internet marketer or "guru" preaches it over and over again. If you build a large list of subscribers then it's easy to make a lot of money with the click of a mouse. It's more complicated than that, and email etiquette plays a major role.

Email marketing should be an essential part of your online marketing efforts and can bring in tons of business. Use promotional email as a form of target advertising, but keep your email filled with information and resources that your subscribers will be interested in receiving.
