closed mailbox with lowered flag

A mailbox with the flag down means there's no new mail. This is what it looks like after the mail carrier has delivered the mail.

Having a mailbox like this in front of your house is convenient. It keeps your mail safe, even in rain or snow.

This mailbox system played a significant role in creating an efficient mail delivery culture. It became a means of indirect communication between mail carriers and residents, while also protecting privacy.

Although email is now commonplace, important documents and special letters are still delivered through physical mailboxes. This traditional mail system becomes even more meaningful during holidays and special occasions.
