The Postal Service’s marketing email policy applies when the Postal Service, or one of its suppliers, sends an email message to a customer or prospective customer that markets a different product or service than the consumer or business customer may already receive from the Postal Service. Managers or employees intending to send a marketing email must submit the email through the Law Department Ad Review process and follow the procedures for notice and choice provided in the CAN-SPAM Act. Complete procedures are available in Management Instruction (MI) AS-350-2004-4, Marketing E–mail.
