What is the function of a mail tray?

The function of a mail tray is to organize and transport mail items during processing. Mail trays are essential tools in the efficient handling of mail, as they allow for categorization and systematic movement of various mail pieces. By using trays, postal workers can group mail by destination, type, or priority, which streamlines the sorting and delivery processes. This organization is critical for maintaining the speed and accuracy of mail processing operations, ensuring that items are delivered promptly and correctly.

Other options, while they might involve aspects of postal operations or office management, do not pertain directly to the primary role of a mail tray in the context of mail processing. For instance, displaying promotional materials or storing office supplies does not align with the fundamental purpose of a mail tray, which is specifically designed for handling mail. Similarly, tracking delivery routes involves logistical operations that go beyond the physical management of mail items themselves.
