USPS Informed Delivery

I tried to track online a USPS parcel, hopeless, something wrong with USPS, however, in the search I signed up with Personal Account. Everyday I get an email with pictures of my mail, which then show up in the mail box. It seemed silly - photos of junk mail, UNTIL BOMB THREATS.  Now I am glad to see what is coming.
