As part of the announcement, FedEx also said it planned to make changes to improve the efficiency of last-mile delivery. Roughly two million FedEx SmartPost packages previously given to the U.S. Postal Service for residential delivery will start to be integrated into FedEx Ground operations.
The release states in part:
“Since 2016, state-of-the-art technology has enabled the movement of a FedEx SmartPost package into the FedEx Ground network when another package is destined to the same or nearby address. This has resulted in the integration of approximately 20 percent of FedEx SmartPost packages to date. Starting this fall, the integration of these packages will be significantly accelerated, and the vast majority of FedEx SmartPost package volume is expected to be integrated into FedEx Ground operations for final delivery by the end of 2020.”
