I have recently started my own business and want to spread about my business card to the area. I have done some research into the fact that the mailbox is basically an off limits zone to my state, Connecticut. However, I don't see anything here about sliding cards through the slots of doors, putting mail on windshields, etc, although some of it sounds like it would just annoy people. Anyone greatly familiar with the USPS deal and the mailbox? Could I stick the card to the front of the mailbox? Any thoughts to this subject would be greatly appreciated.
