What is different between UPS Mail Innovations and UPS Ground/Air?

UPS Mail Innovations specializes in mail and small parcels (any parcel under 1 lb), especially for businesses that push high volumes of small packages per day.

UPS Ground/Air could technically handle the same workload and provide similar shipping speeds, but at much higher rates. UPS offsets their mail and small parcel delivery costs by partnering with USPS, thus building a low-cost mail solution for customers that move large amounts of small envelopes and parcels.
