The term "Future Post" refers to a type of mail delivery service that is currently being developed and tested by the United States Postal Service (USPS). The goal of Future Post is to create a fully automated system for delivering mail, which would involve using drones or autonomous vehicles to transport packages directly to their destinations. This technology could potentially revolutionize the way we receive our mail, making it faster and more efficient than ever before. While there are still many challenges to overcome in developing this new delivery method, the USPS is working hard to make Future Post a reality in the near future.
