Final answer:
Regular mail service in the U.S. includes first-class mail, Parcel Post, Priority Mail, Certified Mail, Media Mail, Express Mail, and Registered Mail. Certified Mail provides a receipt and delivery verification. Despite historical advancements in mail service, the rise of digital communication poses challenges for the future viability of the U.S. Postal Service.
Step-by-step explanation:
Regular mail service includes a variety of options such as first-class mail, Parcel Post, Priority Mail, and other specialized services. In addition to these, regular mail service also includes Certified Mail, Media Mail, Express Mail, and Registered Mail. Certified Mail is a service that provides the sender with a mailing receipt and electronic verification that an article was delivered or that a delivery attempt was made.
Regarding the history of U.S. mail delivery, rural free delivery started in 1902 and helped ensure that people living in rural areas had the same mail rights as those living in the city. This expanded service, along with technological developments, have shaped the U.S. Postal Service we know today.
However, today's Postal Service faces challenges with the rise in digital communication and the cost of operation. These factors raise questions about the future viability of services like Certified Mail and Express Mail, as more individuals and businesses turn to digital forms like email, text, and social media for their communication needs.
