Mail delivery is the process of transporting letters and packages from one location to another. It usually starts when someone drops a letter into a mailbox or takes it to a post office. Postal workers, often called mail carriers, collect the mail and sort it at a central facility. From there, the mail is sent to various locations, ensuring it reaches its final destination. Once the mail arrives at a local post office, mail carriers deliver it to homes and businesses. They follow specific routes, often walking or driving, to ensure that everyone receives their mail on time. This system helps people stay connected, share news, and send important documents.
