So I had this idea when I was leaving my house this morning on my way to work. We all love modern technology. We have smart doorbells, smart thermostats, etc. Why not a smart mailbox? It would be pretty easy. Have about an inch of space in the back to hold the electronics. When it gets opened it would send a message to the smart app and let you know mail has left or arrived. I think it would be handy for a lot of people waiting on their mail. No more little red flag. What do you think?
