FedEx SmartPost is a shipping service that combines FedEx services with the U.S. Postal Service to deliver low-weight packages to residential addresses. The USPS is used for final delivery in order to reach every U.S. address, including P.O. boxes, military APO, FPO, DPO, Alaska, Hawaii and all U.S. territories.
FedEx SmartPost is recommended for online retailers, fulfillment houses, catalogers and direct marketers as a cost-effective solution for shipping. There are no surcharges for Saturday or residential delivery. The maximum weight allowed is 70 pounds. Transit times are usually between two to seven business days in the 48 contiguous states, and longer outside. The liability limit is $100.
