How is Priority Mail Express different from Priority Mail?

Priority Mail Express is distinguished from Priority Mail primarily by its commitment to overnight delivery service. This service guarantees next-day delivery to most locations in the United States, making it ideal for urgent shipments that need to arrive quickly. The specific focus on providing overnight delivery gives customers a reliable option for time-sensitive needs, which is a key feature that sets it apart from Priority Mail, which typically offers delivery within 1-3 business days.

While both services include tracking and insurance benefits, the overnight delivery guarantee is the most significant difference. Priority Mail Express is designed for more immediate delivery requirements and often includes additional benefits, such as a money-back guarantee if the package does not arrive by the promised time.
