There are mail forwarding services[0] that let you automatically filter out junk mail. Yes, they cost money, but at least you can accomplish your goal of opting out (or in) from receiving postal mail from certain senders.
[0] E.g. https://www.usglobalmail.com/virtual-mailbox/If your goal is to receive zero mail at your address, simply have all your email forwarded to this service and configure it to opt-out of all notifications.
Alternately, you can forward your mail to an entirely different address. (This is just a Gedankenexperiment; please don't spam strangers by forwarding your mail to them.)
You will still get mail to your address though...
