direct mail advertising

Contacting carefully targeted prospects with custom tailored offers or promotional material (such as brochures, circulars, letters, newsletters) on one-to-one basis via ordinary mail or email. These mailings almost always carry a response mechanism such as a toll-free number, website address, and/or a business-reply card. In the US, direct mail advertising is the largest single advertising medium totaling over $50 billion per year, or about 35 percent of all annual advertising expenditure.
