CAN-SPAM Compliance Guide

📜 CAN-SPAM Compliance Guide

The Controlling the Assault of Non-Solicited Pornography And Marketing (CAN-SPAM) Act is a U.S. federal law that regulates commercial email communications. It establishes rules for sending marketing emails, requires transparency in sender identity, provides recipients with the right to opt out, and imposes penalties for violations. Unlike GDPR, CAN-SPAM does not require explicit opt-in consent, but it does mandate a clear and easy opt-out process.
