California Anti-Spam Lawsuits: Risks & Compliance for Email Marketing

California Anti-Spam Law Faces Surge in Class Action Lawsuits

Companies relying on email marketing are facing increased legal scrutiny as plaintiffs’ firms file a growing number of class action lawsuits alleging violations of California’s Anti-Spam Law, California Business and Professions Code § 17529.5. These lawsuits target businesses across the United States that send marketing or promotional emails to California residents, regardless of the sender’s location.

What Plaintiffs Are Alleging

Lawsuits center on claims that companies sent misleading commercial emails containing deceptive or forged header information, misleading subject lines, unauthorized domain references, or failed to implement valid opt-in or opt-out mechanisms. Common allegations include inconsistent sender details (mismatched display names and domains, or falsely implying consent), subject lines that mislead recipients about the message’s content, and failures to comply with email authentication standards like SPF, DKIM, or DMARC.

Strict Liability and Potential Exposure

A key aspect of these lawsuits is the assertion that § 17529.5 imposes strict liability on advertisers. This means plaintiffs do not need to prove intent, reliance, actual harm, or damages. Any company benefiting from a commercial email may be held liable, even if the message was sent by a third-party vendor or affiliate. [1] [2]

The statute authorizes liquidated damages of $1,000 per unsolicited commercial email per recipient, potentially leading to multimillion-dollar liabilities in class actions involving large marketing lists. However, courts may reduce these damages to $100 per violation (or $100,000 per incident) if the defendant demonstrates reasonable practices and procedures to prevent unlawful spam emails. [1]

Steps to Reduce Risk

Companies should grab immediate steps to limit potential exposure:

1. Review and Update Email Marketing Practices: Ensure compliance with § 17529.5 and the federal CAN-SPAM Act. Verify the accuracy of email headers, domains, and subject lines. [1]
2. Monitor Third-Party Vendors: Incorporate strong contractual protections requiring vendors, affiliates, and marketing partners to comply with anti-spam laws, and implement oversight mechanisms. Review indemnification provisions in agreements. [1]
3. Maintain Documentation: Preserve records of compliance efforts—including training, audits, technical safeguards, and protocols—to demonstrate due care in litigation. [1]
4. Refine Subject Lines and Content: Ensure subject lines accurately reflect the message content and avoid misleading phrasing. [1]

Bottom Line

California’s Anti-Spam Law presents significant risks for businesses engaged in email marketing due to its strict liability standard and high statutory damages. Proactive review of email practices, strengthened vendor oversight, and thorough compliance documentation are crucial to reduce exposure and defend against claims under § 17529.5. [1]

The CAN-SPAM Act establishes nationwide standards for commercial email and is enforced by government authorities, including the Federal Trade Commission. Non-compliant emails can result in civil penalties of up to $53,088. [1]
