What feature makes express mail delivery different from regular mail?

Express mail delivery is characterized by faster delivery times compared to regular mail. This service is designed to ensure that packages and documents reach their destination more quickly, often by next-day or same-day delivery, depending on the distance and service provider. The expedited nature of express mail is a crucial element for individuals and businesses that require urgent conveyance of materials.

While tracking capabilities are often included with express mail services, which support customers in monitoring the whereabouts of their items during transit, it is the speed of delivery that primarily distinguishes express mail from the standard mailing options. Regular mail typically involves longer delivery times and is more suited for non-urgent correspondence. This is why faster delivery times is the most defining feature of express mail.
