Dictionary of Marketing Terms: junk mail
junk mail
derogatory term used colloquially for promotional mail. The term is most often used by persons who object to receiving unsolicited mail from someone they do not know or do business with. It is not considered an acceptable term in the direct-mail industry. However, one industry speaker, Coleman Hoyt of Reader's Digest, used it quite effectively by saying that junk mail represents all of the undeliverable incorrectly addressed mail that is sent.
