Junk Mail Awareness Week
Junk Mail Awareness Week is held on October 1. Junk mail isn't just annoying. Take a day to think about that and maybe take some action - sign up for Do Not Mail lists, or post a note on your mailbox declaring it a junk mail-free zone. This event in the first decade of the month October is annual.

Junk Mail accounts for 69% of the current Paper Mail volume. Over 19 Billion CATALOGS are mailed out per year in the US alone. On the average Americans get 560 pieces of unwanted mail annually, or about 11 pieces a week.
Contact retailers and mailers and ask them to remove your name from lists for catalogs or contests. When purchasing online or subscribing, check the box that says, "Please do not rent, sell or trade my name or address." Support legislation to allow opting out of ALL direct-mail advertising.
