The CAN-SPAM Act is a law in the United States that sets standards for commercial email and gives recipients the right to have emails stopped from being sent to them. Some of the key requirements for email footers under the CAN-SPAM Act are:


  1. Identification: The sender must clearly identify themselves and their business in the "From" line of the email and in the footer.
  2. Physical Address: The sender must include a valid physical postal address in the footer, which can be the business address or a PO Box.
  3. Opt-out mechanism: The sender must provide a clear and easy way for recipients to opt-out of future emails, such as an unsubscribe link in the footer.
  4. Accurate subject line: The subject line of the email must accurately reflect the content of the message.
  5. No deceptive header information: The "From," "To," "Reply-To," and routing information must not be falsified, and the domain name must not be a mixture of characters that would give a false indication of the origin of the message.


It's important to note that the CAN-SPAM Act is enforceable by the Federal Trade Commission and substantial fines can be imposed for violations.
