Neil O’Keefe, senior vice president of marketing and content at the Data & Marketing Association, says that marketers began questioning direct mail’s endurance in 2007. That year, Statista reports that smartphone sales jumped 70% from the previous year to $8.7 billion. At the same time, the volume of mail sent through the U.S. Postal Service began to plummet: In 2006, people in the U.S. sent 213.1 billion pieces of mail, according to USPS; by 2017, they were sending 149.5 billion pieces each year, a 29.9% decline. By this point, smartphone sales had reached $55.6 billion. The price of postage and paper had skyrocketed, as did the number of internet users—everything seemed to hammer a nail into direct mail’s coffin.
Push marketing is a proactive technique that enables e-marketers to "push" their product/service information to Web visitors or shoppers without their requesting it. Banner advertising, pop-up advertising, e-mail promotion, and spamming belong to push marketing. For instance, e-marketers can rent designated space from Internet service providers such as America Online or MSN for their banner or pop-up ads. Using animated graphics, appealing messages, and links, e-marketers try to lure visitors to their sites to buy their products or services. Many Internet users, however, find such ads annoying and employ software that blocks pop-ups and banner ads. <
