This won't stop the local ads the delivery person is required to put into every box. There should be a legal way to mark your box (on the inside etc) that advertisements aren't allowed. But who are we kidding, this entire country was built on abusing every possible ad space except the backs of the congresspeople. If ads are allowed under "free speech" then forced eyeballs are not a valid method, it has to be contracted and your mailbox is not a contract with sellers. Just like that TV you bought has no right to show you ads without consent.
