A hole in the door for mail

You're referring to a mail slot or a mail chute!

A mail slot is a small opening in a door, typically at a convenient height, that allows mail to be inserted and retrieved without having to open the door or disturb the occupants of the room or building. It's a convenient and secure way to receive mail, especially in busy households or offices where mail may be delivered frequently.

Mail slots are commonly found in:

  1. Residential doors: Many homes have a mail slot in the front door, allowing mail carriers to deliver mail without having to ring the doorbell or disturb the occupants.
  2. Office buildings: Mail slots are often used in office buildings to receive mail and packages without disrupting the work environment.
  3. Apartments: Some apartment complexes have mail slots in the lobby or mailroom area, making it easy for residents to receive their mail.
  4. Mailboxes: Some mailboxes, especially those in rural areas, have a mail slot that allows mail carriers to deposit mail directly into the box.

The benefits of a mail slot include:

  1. Convenience: Mail slots save time and effort by allowing mail to be delivered quickly and easily.
  2. Security: Mail slots provide an added layer of security by keeping mail out of sight and preventing theft or tampering.
  3. Organization: Mail slots help keep mail organized by keeping it separate from other items and preventing it from getting lost or mixed up with other documents.

Overall, a mail slot is a practical and convenient feature that makes receiving mail a breeze!
