People have to pay money to send me physical mail. It's not a lot of money, but it 99% of email spammers would not be able to afford to physical spam me.
True, but I can automate throwing the email into the trash, I have to manually pickup the snail mail at least 3 times a week to keep the mailbox from overflowing. I have a sorting table right next to the trash can. Most days, it all goes into the trash.
I get way less physical mail than email.
