How mail forwarding works starts with a mail forwarding schedule. The customers mail is forwarded through placing their unopened into an envelope or packet then mailed to a destination the customer provided previously. We do not forward 3rd class mail. 3rd class mail defined as advertising and addressed to resident or occupant. Unless you specify on the Mail Handling Privileges form 3rd class mail will not be sent to you. Time sensitive mail can be adjusted to a different schedule if customer gives us a 24 hour notice.
