Mailroom

The mailroom is responsible for a company's incoming and outgoing mail.

A mailroom clerk prepares outgoing mail and packages prior to their being sent out via the post office or other carrier.

The postmaster manages the department, clerks assist them and mailboys deliver mail for other employees in different departments using a mail cart or a trolley doing regular rounds throughout the day.

At a few companies the mailroom is the basis or metonym for a training program for highly promising early-career hires.

U.S. talent agency mailrooms, starting with the William Morris Agency mailroom, became famous for alumni rising to the highest levels in the entertainment industry, documented in the book The Mailroom: Hollywood History from the Bottom Up.
