Postal employees and our high-speed equipment have only a brief second to look at an envelope, read information and enter it for processing. Mail with insufficient information or mail that has insufficient postage, is rejected and returned to the sender endorsed "Return to Sender". This endorsement is very prominent and is designed to be eye-catching. For this reason, we ask that any returned mail, upon be mailed again, be enclosed in a new separate envelope with new postage to ensure prompt processing and to avoid being returned to the sender a second time.
