Direct mail is defined as a way of advertising in which advertisers mail printed ads, letters or other solicitations to large groups of consumers. Bulk-mail rates are used to lower the cost of the mailing, and targeted mailing lists are used to maximize potential response.
This type of advertising is used in many different situations, limited primarily by the imagination of the advertiser. Stores typically use direct mail to advertise new products or to distribute coupons. Charities typically use the it to raise money or recruit volunteers.
