Mail Clerks - Main Mail Clerks Mail clerks process and distribute mail for organizations. Mail clerks usually work for large organizations that need someone to handle the mail.
Internal mail goes between people in the organization.
Clerks sort the internal mail and deliver it to other employees. They often use carts to move the mail between offices. Clerks also handle the mail that will be shipped to people outside the organization. They prepare mail for delivery to the post office. Preparations involve figuring out how the mail should be sent, such as first class or third class.
