The funny part is that they don’t scan the kind of spam that is blanketed to your area like grocery store inserts and local gym offers (the stuff that isn’t actually addressed to you). They do still scan the targeted spam like credit card offers and such. They don’t scan magazines either. Just individually addressed envelopes and postcards.
They scan the stuff sent to "YOU OR CURRENT RESIDENT". I think they don't scan the stuff that is dropped off in a giant stack with orders to deliver to every box in a zip code.
They actually don’t scan most of the spam. Only ones that end up getting scanned are credit card offers and those Comcast ones that try to look like official business letters. Seems more often than not they straight up don’t bother to email me though.
