A mailbox is a container, usually made of metal or plastic, that people use to receive letters or packages from the postal service. Mailboxes are commonly located outside of homes and businesses, and mail carriers deliver letters and packages to them regularly. To use a mailbox, you simply need to open it and put your mail inside, waiting for the postal service to pick it up and deliver it to its intended recipient. Some mailboxes require a key to open them, while others have a simple latch that you can operate by hand. It's important to use mailboxes properly to ensure that your mail gets delivered safely and securely.
