Introduction to Permission-Based Email Marketing
Perhaps one of the most widely used forms of online marketing, the email changed the way direct marketers did business after it was introduced in the mid 1990’s. Before the advent of email, direct marketers had to purchase lists of names and addresses, then pay a good amount of money to ship postcards or envelops to addresses. With email, postage is no longer required (although some major email providers are thinking about introducing certified email programs that charge small amounts for each email sent.)
