With the amount of junk mail people get weekly, I was curious if there are ways you can block, remove or filter the actual mail from ever getting to your mailbox.
Yup, you can put a red dot in your mailbox as an indicator that you don’t want any unaddressed mail. You will still get anything with your address on it and political party mail (they have to deliver those) but it cuts out the best majority of crap.
