USPS Informed Delivery

I find it strangely compelling to see a daily email digest containing digital images of the upcoming postal mail. This new service is provided by USPS, free (I love free) of charge, and is called Informed Delivery. It's not available everywhere and doesn't mean that what you see in today's email shows up that day, but it's pretty close.
