The Hauser Group has been an industry leading provider of mail delivery tracking and list security services since 1991. Hauser also provides DDU tracing (Presence Program), catalog/information online request tracking, market research, and e-mail tracking services. Hauser uses a network of over 3000 agents across the United States and the world to track mail delivery campaigns for direct marketers.

Hauser's real time delivery reports are necessary and vital in this era of instant feedback. With the USPS making postal cost cuts each year, it is more essential to be on top of the delivery patterns as they affect cashflow and response data.
