What is CAN-SPAM Act?
Quick Answer
US law setting rules for commercial email, including required unsubscribe mechanisms and truthful subject lines.
CAN-SPAM (Controlling the Assault of Non-Solicited Pornography And Marketing) is a US law that sets requirements for commercial email: don't use deceptive subject lines; identify the message as an advertisement; include your physical mailing address; provide a clear opt-out mechanism; honor opt-out requests within 10 business days. CAN-SPAM applies to commercial messages, not personal ones. Unlike GDPR, it allows opt-out (not opt-in) consent. Violations carry fines up to $50,120 per email.
