• The Unwanted Pornography and Marketing Act of 2003 (CAN-SPAM) is a federal law that regulates the use of unsolicited e-mail for marketing purposes and provides grounds for taking action against violators. Such emails are generally prohibited by law unless they contain the correct information in the header, the physical address of the sender, and an opt-out mechanism for recipients. Legal liability in connection with violations of CAN-SPAM is generally excluded by standard shared liability policies.
