So delivering leaflets to AllHomes in your area is your mission. You want to reach every single house. However at least 20% of letter boxes now have no junk mail signs.
There is no real law around junk mail signs however it does annoy people if you leaflet no junk mail doors so we avoid this. Cases of Newspapers, free magazines and political correspondence tend to break the rules and we can deliver these to doors with nojunkmail signs.
We would recommend people just doing leaflet campaigns to avoid no junk mail doors when possible as its more hassle than its worth. People have a passion for their junk mail signs.
