Theres e-mail. Theres snail mail. And then theres "Sawmail." Thats what Atlanta remodeler SawHorse calls its use of an old-fashioned black RFD mailbox on site to exchange information with clients during a project.

"When youre tearing up somebodys house, where do you leave the notes for them?" asks SawHorse president Jerome Quinn. For years, the companys answer has been the special mailbox with its bright red flag that lifts up to indicate a message is inside. "Its cleaned up miscommunication," Quinn says. Typically the box contains information that isn't time-sensitive: SawHorse employees use cell phones and e-mail for quick communication.

A side benefit is that the mailbox always sits on top of the safety box, so workers know where to go for first aid.
