Cal. Business and Professions Code § 17529.8

(a) (1) In addition to any other remedies provided by this article or by any other provisions of law, a recipient of an unsolicited commercial e-mail advertisement transmitted in violation of this article, an electronic mail service provider, or the Attorney General may bring an action against an entity that violates any provision of this article to recover either or both of the following: (A) Actual damages. (B) Liquidated damages of one thousand dollars ($1,000) for each unsolicited commercial e-mail advertisement transmitted in violation of Section 17529.2, up to one million dollars ($1,000,000) per incident. (2) The recipient, an electronic mail service provider, or the Attorney General, if the prevailing plaintiff, may also recover reasonable attorney’s fees and costs. (3) However, there shall not be a cause of action against an electronic mail service provider that is only involved in the routine transmission of the unsolicited commercial e-mail advertisement over its computer network. (b) If the court finds that the defendant established and implemented, with due care, practices and procedures reasonably designed to effectively prevent unsolicited commercial e-mail advertisements that are in violation of this article, the court shall reduce the liquidated damages recoverable under subdivision (a) to a maximum of one hundred dollars ($100) for each unsolicited commercial e-mail advertisement, or a maximum of one hundred thousand dollars ($100,000) per incident.
