To be CAN-SPAM compliant, any commercial message, whether to one person or one thousand, must contain an opt-out unsubscribe mechanism and the sender's postal mailing address; both are automatically provided using the system's default CAN-SPAM compliance footer.

To include the CAN-SPAM footer in your message, check the CAN-SPAM box on the PoliteMail toolbar. The footer includes merge fields that are filled when the message is sent.
You can make changes to the footer (add text, change the font, etc.) in your message, but those changes will not be saved as the default. To save changes, save the message as a paragraph or template, or edit the default footer.
DO NOT remove the your postal mailing address or the Opt-out link. To be CAN-SPAM compliant, your footer MUST INCLUDE both.
