Actually, no...
The post office is not allowed to stop mail addressed to 'occupant'. That's all I get, stupid supermarket flyers that require me to go check the mail simply to ignore them. I ended up paying for a PO box, and now only have to check it once every 3-4 months.
I think that "occupant" still counts as addressed if it also has a street address etc.. By unaddressed I mean that there is no address at all, they are just delivered to every mailbox in a specific area (except for "no ads" boxes).
No address? That doesn't happen - is it still the post office delivering unmarked mail? That would be illegal here since only the USPS can legally use mailboxes.
With this service the USPS is adding addresses from its database based on the area(s) the customer selects. It's not mail with no address showing up in people's mailboxes.
EDDM is not addressed, I get it in my mailbox every week and it absolutely is not addressed -- read further down the page I linked:
> Mailpieces are simply addressed to "Postal Customer" and your mail will be delivered to every address on your selected routes.
The area the customer selects are carrier routes. When you select a route, the carrier is given a stack of your fliers and they simply hand one out to each address.
In many European countries (all that I'm aware of), anyone can use a mailbox. You can deliver mail personally, there sometimes are local mail delivery services and they're used for advertising. In the end that makes it easier to avoid Spam as you can opt out of anything not sent to you directly.
