I ran into my mail lady when I was getting my mail the other day. Turns out she had just tossed everything a few days before and started lecturing me on not letting my mailbox fill up.

I went there to get a new card that Id been informed was sent a few days ago and asked her how it got so full.

Then I saw all the junk mail she was shoving in and , not thinking, asked her if I could unsubscribe from all the obvious crap because mail is almost useless these days. She got a sad look on her face and I almost felt bad

You can actually! You have to pay like $3 to unsubscribe from junk mail (ridiculous, right?), but you can! You have to unsubscribe from pre-screened credit cards separately. I did both a couple years ago and reclaimed my mailbox.

For junk mail:

For CC bullshit:
