In the United States, using AI to write a marketing email does not by itself transfer responsibility for the advertising claims away from the advertiser. The business whose product is promoted may also share responsibility under CAN-SPAM with the business that sends the message. Which parties could be liable in a particular case depends on the facts and applicable law.
Who is responsible for the claim itself?
The advertiser must ensure that express and implied claims in its advertising are accurate and supported. The Federal Trade Commission (FTC) says advertisers should assess the overall impression made by the ad, including its text, images, and graphics. AI-generated wording does not create an exception to that standard in the cited FTC guidance.

A statement can mislead through what it implies, not just through its literal wording. FTC guidance says advertising claims must be truthful, not deceptive or unfair, and evidence-based. The business should therefore review what a reasonable reader might take away from the complete email, rather than checking only whether individual sentences are literally true.

Does using AI or an email agency make the company less responsible?
No—not simply because the content was generated by AI or the campaign was outsourced. FTC guidance does not set out a special AI-specific liability rule, nor does it decide the responsibility of a particular AI provider, employee, agency, or sender. But the advertiser’s duty to ensure its claims are accurate does not disappear because a tool drafted them.

For CAN-SPAM compliance, the FTC says both the business whose product is promoted and the business that sends the email may be legally responsible. It also states that hiring an email-marketing company does not let a business contract away its legal responsibility to comply with the law. The arrangement between a company and its vendor does not, by itself, settle who may be responsible under the law. FTC, CAN-SPAM Act: A Compliance Guide for Business.
How is a false product claim different from a CAN-SPAM violation?
They are separate questions. A misleading statement about a product or service in an email may fall under deceptive-advertising law, including Section 5 of the FTC Act. CAN-SPAM, by contrast, addresses practices associated with commercial email, including false or misleading header information and deceptive subject lines. It also requires covered commercial messages to identify themselves as advertising and provide an opt-out method.
An email can raise concerns about both its advertising claims and its sending practices; satisfying one set of rules does not establish compliance with the other. CAN-SPAM covers commercial messages, including business-to-business email—not just bulk email. The FTC guide describes the law’s application in terms of a message’s primary purpose. FTC, CAN-SPAM Act overview; FTC, CAN-SPAM Act: A Compliance Guide for Business.
What should a business check before sending?
- Substantiate the claims: Check that factual statements about the product or service have adequate support, including claims the wording implies.
- Review the email’s overall impression: Assess the combined effect of the copy and any images or graphics, not just isolated sentences.
- Check the message’s primary purpose and sending practices: Determine whether CAN-SPAM applies and review the applicable requirements for headers, subject lines, advertising identification, and opt-out.
- Clarify the parties’ roles: Identify the business promoting the product and the business sending the message; outsourcing alone does not remove compliance responsibility.
What this general answer cannot determine
This is a U.S. federal baseline, not a decision about a specific campaign or dispute. The FTC guidance cited here does not determine whether a particular AI vendor, employee, agency, sender, or advertiser would be liable. The wording and presentation of the email, the parties’ conduct, and other facts may matter; state, foreign, and sector-specific laws may also apply.
