Consumers Prefer AI Content — Until It's Labeled
Surveys from Validity and Bynder reported in MarTech show a paradox: consumers often prefer AI-written content when they don't know its origin but penalize brands once AI authorship is disclosed. Validity data (500 U.S. marketers; 1,000 U.S. consumers) finds 74% of marketers are deploying or testing AI-generated content and 43% plan to increase investment. Validity also reports 40% of consumers would trust retailer marketing emails less if they knew they were AI-written, while 55% now make inbox decisions based on AI-generated email summaries. A Bynder study of 2,000 U.K./U.S. consumers showed unlabeled AI copy was chosen as more engaging by 56% of those with a preference, but 52% felt less engaged when told the piece was AI-generated. The article outlines email strategy implications including subject-line auditing, attribution changes, and light-touch disclosure policies.
The research highlights a growing trust penalty for disclosed AI content that directly affects email marketing effectiveness, attribution metrics, and measurement practices—key operational concerns for marketers and MarTech providers.

Study: Brands Thrive Next to Creative AI Content
A new survey by OM Media Trials (Omnicom Media) and Zefr of nearly 5,000 U.S. and Canadian respondents examined consumer reactions to ads shown after eight types of AI-generated video. Results show mixed outcomes: ads placed next to AI-generated satire, youth depictions, or artistic content produced positive brand perceptions (refreshing/innovative), while ads adjacent to AI spam or misinformation — especially about public figures — provoked negative responses. The study found 32% of people sometimes misattribute human-created content as AI, and 41% reported improved brand opinion when AI-created content was clearly labeled. The article cites examples of problematic AI-created ads (Valentino, McDonald’s) and cites a Gartner projection that 90% of internet content could be AI-created by 2030. The authors emphasize disclosure and contextual alignment as ways for brands to manage risk.
Consumers Want AI Ads with a Human Touch
A Canva report, highlighted by MarTech, finds consumers are ambivalent about AI-generated marketing: they value relevance and helpful personalization but react negatively to content that feels robotic, emotionally empty, or invasive. Major findings include that 70% of respondents can spot AI-generated ads, 74% are more likely to buy from ads they believe were created entirely by humans, and 87% say the best advertising still needs a human touch. Consumers accept AI when it improves usefulness (68%), but demand data protection (53%), disclosure of AI use (52%), and an opt-out option (37%). Younger cohorts are more tolerant of AI polish if humans remain involved.
Consumers Embrace AI, But Trust Remains Elusive
A global Klaviyo study of nearly 8,000 consumers finds widespread AI usage but low full trust, creating a gap marketers must navigate. Sixty percent of respondents use AI tools at least weekly, yet just 13% say they completely trust AI. The research reports that 41% purchased a product recommended by AI in the past six months and 27% were introduced to a product by AI that they later researched. Klaviyo segments consumers into four AI personas — Enthusiasts (about 26%), Evaluators, Skeptics and Holdouts (about 21%) — noting Enthusiasts and Evaluators together represent nearly 70% of consumers. Heavy AI users are more likely to spot low-quality AI-generated marketing. Consumers are also shifting search behavior toward longer, more contextual prompts, signaling AI is becoming an important discovery layer even as trust lags adoption.
