I’ve been using Informed Delivery from USPS for over 5 years now, and am generally a big fan. However, I’ve noticed that every once in a while I’ll catch a scan of a piece of mail that is not addressed to me. Notice, the image contains 2 pieces of mail. The one in front is addressed to some unknown neighbor in my zip code. And while it’s probably not the biggest deal, I find it interesting that USPS sends me pictures of other people’s mail, and almost certainly sends pictures of my mail to my neighbors every now and again.
