Description:

CAN-SPAM stands for "Controlling the Assault of Non-Solicited Pornography and Marketing." It's a U.S. law passed in 2003 that establishes the rules for commercial email and commercial messages, it gives recipients the right to have a business stop emailing them, and outlines the penalties incurred for those who violate the law. For example, CAN-SPAM is the reason businesses are required to have an "unsubscribe" option at the bottom of every email.
