GreenDimes.com promises to stop up to 90 percent of household junk mail and plant five to 10 trees on behalf of anyone who signs on for just $20. It’s a one-time investment; if a customer moves, the service may be refreshed for only $10. It definitely beats spending hours on the phone begging to be removed from mailing lists, often with precarious success.

GreenDimes.com will remove clients from junk mail lists, stop unwanted catalogs and monitor monthly list status to eliminate endless frustration. “Now I’m only getting three to four pieces of mail a day—real mail, not junk,” says one member. Another corporate member gifts subscriptions to clients as a thank-you for their business. He explains, “It’s aligned with our office mission to go green.”
