How often is Express Mail available for delivery?

Express Mail, also known as Priority Mail Express, is a reliable and expedited service offered by the postal service that guarantees delivery every single day, including weekends and holidays. This unique feature of the service ensures that customers can send time-sensitive documents and packages without worrying about the day of the week or public holidays, which are critical considerations for urgent shipments. Thus, the service's availability every day of the year supports the needs of businesses and individuals requiring fast delivery. This constant accessibility distinguishes it from other mailing options that may only operate on business days.
