Wow, I live in Queensland, Australia, and here if you put up a sign on your letterbox that says "Australia Post Only" or "No Junk Mail" or similar, your junk mail intake drops to basically zero immediately -- it's really effective. So effective actually that I've never had to lookup what actions to take if I still receive junk mail, because it just never happens. I looked it up just now and found this: https://www.ehp.qld.gov.au/waste/advertising-material.html

I am in Norway and all I have to do is put a sticker on my mail box, which basically says "No unsolicited mail" which stops the postman from filling my mailbox with junk mail. I usually take off the sticker during Christmas or near black Friday, so I can see if I am missing out on any good deals.

I wonder, if it would make sense, to have a service, which would receive all your mail, sorts it for you, throws out the junk, scans the rest and email that to you. In Norway, I rarely receive any important physical mail, especially since the government has started a secure email service[0], where you can receive your payslip and other important documents from government departments. The senders are pre authorized and pay a small fee to send an email to the user but the service is free for the user of the service.

I am in Canada so I don't know how things work south the border. But I heard from a neighbour, and a postman confirmed, that if you stick a piece of paper in your mailbox saying "please don't put ads", they won't do it.

There was a service like this, right? It opened and scanned all of your mail and sent it through email. Junk mail wasn't scanned.

You can contact your local USPS office and just tell them you do not want the junk mail - and they will no longer deliver it.
