Write the general guidelines for operating the mail, but always check with your organization for its preferred procedures?

Sure, here are some general guidelines for operating mail:

1. Sort incoming mail daily and distribute it to the appropriate person or department as soon as possible.
2. Use correct postage and take care when addressing envelopes to avoid delays in delivery.
3. Always handle confidential or sensitive mail separately and ensure it is delivered only to the intended recipient.
4. Ensure that outgoing mail is collected and sent out regularly and that it is correctly addressed and properly stamped.
5. Keep the mailroom clean, tidy and well-organized, and ensure that mail processing equipment is properly maintained and in good working order.

However, it’s important to note that each organization may have specific procedures or policies for handling mail, so it's always a good idea to familiarize yourself with your organization's preferred procedures to ensure that you are operating within their guidelines.
