    The mailroom clerk receives mail and packages from the carrier or postal delivery, checking the piece count against the delivery manifest before signing for it.

  2. 5.2

    Screen for suspicious items

    Mailroom Clerk

    The mailroom clerk visually screens each item for signs of a suspicious package, such as an unexpected sender, excessive postage, or unusual weight or odor, before sorting it.

    Warning: Do not open a suspicious item. Isolate it and notify the office manager immediately.

  3. 5.3

    Sort mail by department and recipient

    Mailroom Clerk

    The mailroom clerk sorts mail into department slots or bins based on the addressee, using the internal directory to route mail addressed to a title rather than a name.

  4. 5.4

    Log certified and signature-required mail

    Mailroom Clerk

    The mailroom clerk records the sender, recipient, date and tracking number for any certified, registered or signature-required item in the mail log before delivery.

    Checkpoint: Every tracked item has a matching log entry and a recipient signature on delivery.

  5. 5.5

    Route confidential mail unopened

    Mailroom Clerk

    The mailroom clerk delivers any item marked personal or confidential directly to the named recipient without opening it, even if the mailroom normally opens department mail.

  6. 5.6

    Deliver mail to recipients

    Mailroom Clerk

    The mailroom clerk delivers sorted mail to department mail stations or hands tracked items directly to the administrative assistant or recipient, obtaining a signature where required.

  7. 5.7

    Mailroom Clerk

    The mailroom clerk weighs and packages outgoing items requested by department managers, applies the correct postage or courier label, and confirms the destination address.

  8. 5.8

    Dispatch outgoing shipments

    Mailroom Clerk

    The mailroom clerk hands off outgoing mail and packages to the postal carrier or courier by the daily pickup cutoff and retains any shipping receipts or tracking numbers.

  9. 5.9

    Handle undeliverable mail

    Mailroom Clerk

    The mailroom clerk sets aside mail for employees who have left the company or for an unrecognized address, and forwards or returns it following the office manager's guidance.

  10. 5.10

    Confirm receipt of tracked deliveries

    Administrative Assistant

    The administrative assistant confirms with the recipient that a tracked or certified item was received and notifies the mailroom clerk if an expected item did not arrive.

  11. 5.11

    Reconcile courier and postage accounts

    Office Manager

    The office manager reviews the monthly courier and postage statements against the mail log and shipping receipts to confirm charges are accurate before approving payment.

    Checkpoint: Courier and postage charges match logged shipments before the invoice is approved.

  12. 5.12

    Restock mailroom supplies

    Mailroom Clerk

    The mailroom clerk checks envelope, label and packaging supply levels weekly and submits a request to the office manager when stock is running low.

A package arrived with no return address and it feels unusually heavy for its size, what do I do?

Do not open it. Set it aside away from other mail and people, and notify the office manager right away so it can be assessed before anyone handles it further.Source: step 5.2 ยท Screen for suspicious items
