The invention provides a holder for manual delivery of mail to a recipient having one or more alert marks thereon which signify that a predetermined action should be taken during mail delivery. The holder may be a bag, folder or any similar device suitable for holding mail and accepting printing. The alert marking distinguishes the holder from others lacking such a mark and prompts the mail carrier to inspect the holder's contents for a potential problem, such as mail not properly deliverable to that address.
