CAN-SPAM stands for "Controlling the Assault of Non-Solicited Pornography and Marketing." The CAN-SPAM Act is a 2003 law in the United States of America (USA) that sets the rules for commercial (ie: business) email, establishes requirements for commercial messages, gives recipients the right to have businesses stop emailing them, and spells out the penalties for violations. CAN-SPAM is the reason all business emails are required to include an "Opt-Out" or "Unsubscribe" link or preferences page for consumers.
