What happens to undelivered FCM that has no forwarding address?

When it comes to undelivered First-Class Mail (FCM) that lacks a forwarding address, the proper procedure is to return it to the sender without processing. This is important for maintaining the integrity of the mail delivery system and ensuring that senders are informed about the issues with their mail.

FCM, being a premium service, has specific handling rules that emphasize the importance of returning undelivered items to the sender. This allows the sender the opportunity to either provide a new address if they have it or to take other necessary actions regarding the mail.

Returning it to the sender also aligns with postal regulations that govern how different classes of mail are treated in the case of non-delivery. In contrast, options that suggest discarding or forwarding to a default address do not follow the standard protocols for handling undeliverable First-Class Mail. This process ensures that all parties involved are kept informed and that the system upholds a high standard of service.
