Direct mail

Although bulk mail, junk mail, and admail are, strictly speaking, not synonyms, the terms are used in common parlance to refer to advertising circulars, free trial CDs, pre-approved credit card applications, and other unsolicited merchandising invitations delivered by mail to homes and businesses.

The term "junk" is usually used when someone receives an item of mail that is untargeted or not relevant to them. Bulk mailings are a particularly popular method of promotion for businesses operating in the financial services, home computer, and travel and tourism industries.

Advertisers often call it "targeted mailing", as mail is usually sent out following database analysis. For example a person who likes golf may receive direct mail for golf related products or perhaps for goods and services that are appropriate for golfers. The USPS prefers to call it "advertising mail" (admail for short), noting that some people might find offers of interest to them in it.

Some people respond positively to direct mail advertising and find useful goods and services on offer. Traditionally, this was more true in rural areas where people had to travel many miles to do their shopping and direct mail and mail order shopping was a major convenience. However, many people dislike it, in the same way as with telemarketers' calls and e-mail spam, and some jurisdictions like the US have laws requiring junk mailers to withhold their offerings from residents who opt out.

Many consumers, as well as environmental protection groups, are concerned about the environmental impact generated by junk mail.
