Direct Mail differs from regular advertising in that it does not place its messages on a third
party medium, or in the agora, such as a billboard or a radio commercial would. Instead,
the marketing of the service or commodity is addressed directly to the consumer. Direct
Mail utilizes not only names and addresses, but also social, economic, and lifestyle
information. Used as part of a marketing strategy, they can vary in shapes and sizes
but usually conform to standard mailing requirements.
