Snail mail is mostly obsolete now. Kind of dangerous, don't you think? They rely on email, apps and text messages to reach you. Yes, the spammers do that, too, but what if you lose power? What if your interwebz disappear for a few weeks?
We don't get much snail mail spam these days, just the occasional official letter or bill. Remember when they'd send you yearly phone books?
You seem to be lost in your own thoughts.
