What is the difference between saving an address to the Address Book and saving a shipment to my Fast Ship profiles?
Saving an address to your Address Book will store the recipient’s address and e-mail information. Saving a shipment to your Fast Ship profile will save the service type, package type, weight, reference information and any special services used for the shipment. When you send a shipment using a Fast Ship profile, Ship Manager at FedEx.com will use these settings and automatically generate your label.
