Direct-mail marketing is a process of direct marketing by sending an offer, announcement, reminder, or other item to a person at a particular physical or virtual address. Using highly selective mailing lists, direct marketers send out millions of mail pieces each year-letters, catalogs, ads, brochures, samples, DVDs, and other “salespeople with wings.” Direct mail is by far the largest direct marketing medium. The DMA reports that U.S. marketers spent $44.4 billion on direct mail last year (including both catalog and non catalog mail), which accounted for 32 percent of all direct marketing spending.
