The USPS said on Wednesday that mail volume has declined in the first quarter of fiscal 2008. In their announcement the Postal Service said preliminary financial results indicate mail volume was down 3.0 percent, or 1.7 billion pieces. First-Class Mail volume decreased 3.9 percent and Standard Mail decreased 2.6 percent in the quarter ending Dec. 31, 2007.

Postmaster General John Potter pointed to the downturn in finance and housing, both of which are heavy users of mail for the volume sag. H. Glen Walker, Chief Financial Officer and Executive Vice President also pointed to "disturbing trends" in U.S. economy for the drop in mail volume.
