FedEx is really the airline (all the time) or long-haul, inter-city transport (most of the time).
The guys who come to your doors to do a delivery are generally not FedEx employees, instead they work for a local franchisee who scored the winning bid to serve that particular route (similar to candy/soda vending machine "contract routes").
FedEx Home is another flavor of this.
As is FedEx Custom Critical.
In general, residential delivery is one of the more expensive operations a carrier can undertake (at least in the US). So almost everyone who does large volume is scrambling to find cheaper ways to deliver their goods to you, such as:
- FedEx SmartPost (FedEx on the long haul, USPS on last mile)
- UPS SurePost (UPS on the long haul, USPS on last mile)
- LaserShip (Pick up from local Amazon warehouse, deliver to last mile)
- USPS Contract Delivery Service ($carrier on long haul, independent contractor for last mile)
- USPS in general (FedEx, UPS, or contract carrier on long haul, USPS employee for last mile)
