Junk mail keeping the US Postal Service alive.

No wonder why my mail carrier is so cranky. From Newsweek:

These are tough times for the U.S. Postal Service. It's being pummeled by high fuel costs. The soft economy is crimping the overall volume of mail, which fell 5.5 percent in the past year. Its business is also falling as Americans opt for e-mail over birthday cards and thank-you notes. Now comes another threat: consumers like Colleen Plimpton of Bethel, Conn. Earlier this year Plimpton became tired of the credit-card offers, catalogs and advertising fliers that clogged her mailbox. So in February she paid $20 to GreenDimes, a firm that helps consumers reduce their inflow of "junk mail" by contacting businesses on their behalf. "[Junk mailers] are cutting down trees willy-nilly, and that has got to stop," says Plimpton.

To the post office, consumers like her are a serious threat. "Efforts to convince people not to receive mail are really going to hurt," says Steve Kearney, a Postal Service senior vice president.

The Postal Service lost $1.1 billion in its latest quarter. That number would be even larger if it weren't for direct mailings, which now constitute 52 percent of mail volume, up from 38 percent in 1990. Revenue from direct mail "is the financial underpinning of the Postal Service—it could not survive without it," says Michael Coughlin, former deputy postmaster.
