The CAN-SPAM Act is a law that sets the rules for commercial email, establishes requirements for commercial messages, gives customers the right to opt out of receiving unsolicited commercial email messages, and spells out tough penalties for violations.
In order to comply with the CAN-SPAM Act, all commercial email messages must:
• Include a clear and conspicuous notice that the message is an advertisement or solicitation and that the recipient can opt out of receiving future emails from the sender;
• Include a valid physical postal address of the sender;
• Include a clear and conspicuous subject line that is not misleading; and
• Be free of viruses or other malicious code.
