> I suppose that's because you have mailboxes outside with little flags rather than letterboxes in doors

That's mostly only rural areas. Where I am, the houses either have letter slots in the door as you described, or a letter box attached to the house next to the front door.

Our previous place had a letter slot. But the place we just moved into has put the letter box next to the side door, at the end of the driveway. It's hit-or-miss where deliveries will get left, but most of the time it's at the front door, the one we don't check on a regular basis because we're usually going out the side door to get to our cars.
