As of .
What it requires
- Do not advertise in a commercial email sent from California, or sent to a California email address, that contains or is accompanied by a third party's domain name used without permission, falsified, misrepresented, or forged header information, or a subject line you know would likely mislead a recipient, acting reasonably, about a material fact regarding the message's contents.
- You are not liable under this section if you are an electronic mail service provider only involved in the routine transmission of the email advertisement over your network; you also avoid liquidated damages, though not actual damages, by establishing and implementing practices reasonably designed to prevent a violation.

What this law does
Section 17529.5(a) makes it unlawful to advertise in a commercial email advertisement sent from California or to a California email address that contains or is accompanied by a third party's domain name used without permission, falsified, misrepresented, or forged header information, or a subject line a person knows would likely mislead a recipient about a material fact regarding the message's contents.
Section 17529.5(b) lets the Attorney General, an electronic mail service provider, or a recipient of the unsolicited commercial email sue for actual damages, or liquidated damages of $1,000 for each violating email up to $1,000,000 per incident (reduced to $100 per email, up to $100,000 per incident, if the defendant shows it had established and implemented due-care practices to prevent violations), plus attorney's fees and costs for a prevailing plaintiff; a claim under this section forecloses a separate claim under sections 17529.8 or 17538.45 for the same email, and there is no cause of action against an email service provider only routinely transmitting the message.
Section 17529.5(c) also makes a violation a misdemeanor punishable by a fine of up to $1,000, imprisonment in county jail for up to six months, or both. The federal CAN-SPAM Act's preemption clause supersedes a state statute that expressly regulates commercial email, except to the extent the state statute prohibits falsity or deception in the message. Section 17529.5's duties are framed as exactly that kind of falsity-or-deception rule, the kind CAN-SPAM's preemption clause leaves in force.
California's broader, non-deception-based commercial-email ban, section 17529.2, is framed instead as a flat ban on any unsolicited commercial email regardless of truthfulness, and is not researched here as a separate instrument for that reason.
