I saw a friend's blog and realized how easy it is in Sweden to say "no thanks" to spam in the mail.
You simply make a sign or write a note that says "no fliers, please" and the person delivering inserts and such is not supposed to put junk mail in your mailbox.
Mostly, this is made possible because mail is delivered to each and every apartment in Sweden through a small mail slot in the front door. If the sign is on the door, it stops unwanted mail.
It is also possible because companies hire a separate staff to distribute fliers and such, unlike in the United States, where it all has to be sent via the U.S. Postal Service. Here, you have to visit the post office or its web site to stop unwanted mail, but you also run the risk of stopping magazines or free newspapers if you opt out.
And most companies use newspapers to distribute their fliers and inserts, because it's the most convenient way to reach the consumers. Unless you live in a house and has a mailbox by the road, most people's boxes are locked and unaccessible.
I wish I could just put a sign up on our box though that says "stop putting junk in here! Mailman, take that crap back with you when you leave!" but I'm afraid that's not allowed, nor would anyone adhere to it (It is, after all, a federal crime to tamper with anyone else's mail in any way).
No wonder our recycling bin is full before our two weeks are up! And we don't even have a daily newspaper at our house (despite working for newspapers, or perhaps because we both work for newspapers, we do not want one at our house every day).
