Washington Commercial Email Requirements — Compliance Snapshot

Washington Commercial Email Requirements — Compliance Snapshot

Last Reviewed: September 15, 2026

 

Washington At a Glance.

Washington has its own law regulating certain commercial email practices: the Commercial Electronic Mail Act (CEMA), Chapter 19.190 RCW.
CEMA is particularly important for businesses sending promotional email to Washington residents because it addresses sender/origin information and false or misleading subject lines. Washington also amended the law in 2026 following significant litigation involving promotional email subject lines.
For businesses, the practical takeaway is important:
Compliance with the federal CAN-SPAM Act should not automatically be treated as the end of the email marketing compliance analysis for Washington recipients.
Federal CAN-SPAM generally preempts state laws specifically regulating commercial email, but it preserves state-law provisions addressing falsity or deception. Washington’s Attorney General explains that Washington’s anti-spam law operates alongside the federal law because of its focus on falsity and deception.

 

Law.

Washington Commercial Electronic Mail Act (CEMA)
Citation: Chapter 19.190 RCW
Primary Email Provisions: RCW 19.190.010–.050
2026 Amendment: Engrossed Substitute House Bill 2274, Chapter 135, Laws of 2026
2026 Amendment Effective Date: June 11, 2026

 

What Is a Commercial Electronic Mail Message?

For purposes of CEMA, a “commercial electronic mail message” is generally an email sent for the purpose of promoting real property, goods, or services for sale or lease.
That definition makes the law particularly relevant to businesses using email for advertising, promotions, sales offers, and similar commercial purposes.

 

When Can Washington CEMA Apply?

The email provisions can apply when a person initiates, conspires to initiate, or assists the transmission of a commercial electronic mail message:
  • From a computer located in Washington; or
  • To an email address that the sender knows, or has reason to know, is held by a Washington resident.
The statute also contains a specific provision addressing when a sender is considered to know that an intended recipient is a Washington resident.

 

✔ CLIClaw Tip: Do not evaluate Washington email risk based solely on where your business is located.
A business located outside Washington may still need to evaluate CEMA when its commercial email campaigns reach Washington residents.

 

What Does Washington CEMA Prohibit?

CEMA prohibits certain deceptive practices involving commercial email.
1. Unauthorized Use of a Third-Party’s Domain Name. A commercial email may not use a third-party’s internet domain name without that party’s permission.
2. Misrepresentation or Obscuring of Origin or Transmission Information. The law prohibits commercial email practices that misrepresent or obscure information identifying the point of origin or transmission path of the message.
For businesses, this makes sender identity and the technical origin of a commercial message important compliance considerations.
3. False or Misleading Subject Lines. Washington also regulates false or misleading information in commercial email subject lines.
This provision has become particularly significant because of litigation involving promotional subject lines, including claims involving limited-time sales and statements suggesting that an offer was ending.

 

Important: Washington Amended CEMA in 2026.

Businesses reviewing these earlier cases should be aware that Washington subsequently amended CEMA in 2026, including adding a knowledge standard to the subject-line provision.
Current compliance analysis should therefore begin with the current statute, rather than relying exclusively on decisions interpreting the earlier statutory language.

Washington Case Law Has Increased Attention on Subject Lines.

Washington courts have examined how CEMA applies to allegedly false or misleading promotional email subject lines.
In Brown v. Old Navy, LLC, the Washington Supreme Court addressed the scope of CEMA’s subject-line restrictions and interpreted the version of the statute then in effect broadly enough to reach false or misleading information beyond simply whether an email was commercial in nature.
The decision increased attention on promotional subject-line practices and was followed by a significant 2026 legislative amendment to CEMA.

Promotional Email Litigation Continues.

Ma v. Nike, Inc. provides another example of litigation involving promotional email subject lines under Washington law. The lawsuit challenged subject lines associated with limited-duration promotional offers, and in January 2026 the federal district court allowed the CEMA claim to proceed beyond the motion-to-dismiss stage.
The case is useful for understanding how Washington’s commercial email law has been asserted in private litigation.

CEMA and CAN-SPAM Are Not the Same.

Businesses should distinguish between the federal and Washington frameworks.
Federal CAN-SPAM establishes broad federal requirements for commercial email, including requirements concerning sender information, subject lines, advertising identification where applicable, physical postal addresses, opt-out mechanisms, and honoring opt-out requests.
Washington CEMA creates additional state-law considerations focused particularly on deceptive commercial email practices, including origin/transmission information and subject lines.
Washington’s Attorney General expressly recognizes the continuing role of Washington’s law alongside CAN-SPAM because federal preemption preserves state provisions addressing falsity or deception.

 

Where Washington Fits in the Email Marketing Compliance Journey.

  • Determine whether Washington CEMA and other applicable requirements affect the organization’s campaigns.
  • Establish campaign, sender, list, affiliate, vendor, and governance procedures.
  • Apply those procedures during campaign development, review, approval, and deployment.
  • Make sure relevant personnel understand subject-line, sender, escalation, and documentation expectations.
  • Audit & Defend. Test whether established controls are operating and whether the organization can locate evidence supporting important campaign decisions.
