Mail-O-vation

I had ordered a laptop skin from SkinIt.com. As I was tracking my shipment, I noticed a new delivery method called UPS Mail Innovations. On further reading, I realized that it is not new, it has been in existence since 1997. Darn my ignorance!

Anyways, for those who think like me that only a "S" differentiates the two companies, here is some context -

UPS is a publicly-traded company that stands for United Parcel Service. USPS stands for the United States Postal Service and is a quasi-governmental agency. USPS is self-funded through the sale of postage stamps and delivery services. (Source)

So, the UPS Mail Innovation works as depicted below -

UPS Mail Innovations (UPS MI) has been a National Account of the United States Postal Service (USPS) business partner segment since 1997.  Through this work-share partnership, we provide global mail services.

The program works like this:
UPS MI picks up the mail, processes (sorts) and transports your mail to the USPS.

Then:
The USPS accepts your mail piece and makes the final delivery to your mailing address.
