Advertising mail

Distribution of advertising by direct mail or letterbox drop

Advertising mail, also known as direct mail, junk mail, mailshot or admail, letterbox drop or letterboxing (Australia), is the delivery of advertising material to recipients of postal mail. The delivery of advertising mail forms a large and growing service for many postal services, and direct-mail marketing forms a significant portion of the direct marketing industry. Some organizations attempt to help people opt out of receiving advertising mail, in many cases motivated by a concern over its negative environmental impact.
