Postal mail refers to the system of sending letters, packages, and other items through a network of postal services. This method allows individuals and businesses to communicate and send goods over long distances. Postal mail is typically delivered to homes and businesses by postal workers, who use various modes of transportation, including trucks and airplanes.
The process of sending postal mail usually involves placing the item in an envelope or package, addressing it with the recipient's information, and affixing the appropriate postage, which is often a stamp. Postal services, such as the United States Postal Service (USPS) or Royal Mail, ensure that mail is collected, sorted, and delivered efficiently.
