While updating the Stop Junk Mail website in June 2011 I found that quite a few campaigns abroad have disappeared… Suggestions for more campaigns outside the UK are welcome (hurry to the contact page).

• Do Not Mail is an American campaign for a 'do not mail' register which would give Americans a proper opt-out system for junk mail
• Canada has a rather fancy 'No Junk Mail' sticker: the Red Dot.
• A personal favourite of mine: It's Damp gives away free 'no junk mail' stickers to Australians. The stickers are based on the 'No/No', 'No/Yes' stickers I used to sell myself.
• Letterboxer is an interesting campaign in New Zealand: volunteers go door-to-door to give away 'No Junk Mail' stickers.
