Data Trust Crisis: Customer Data Quality Declines
The article warns that marketing organizations face a growing "data trust" crisis: privacy changes, fragmented platforms, and AI-generated/inferred signals are degrading the accuracy and reliability of customer data. It promotes a MarTech Conference session (online, Sept. 2, 2026) titled “The data trust crisis: Why your customer data is getting worse,” featuring speakers from Actable, Razorfish, Tealium, and Ana Mourão, which will examine technical and regulatory drivers of data decay and methods (e.g., confidence-scored approaches, governance playbooks) for maintaining personalization and measurement when datasets are imperfect.
Highlights operational risks to personalization and measurement from worsening customer data quality, but is a conference/session-level discussion rather than a major platform policy or product change.

Data Quality: The Key to AI's Marketing Future
AI systems are only as good as their data. The article argues that the next standard for AI in marketing is data quality defined by accuracy, freshness, consent, and interoperability. Accuracy means signals anchored to real human identity; freshness means ongoing updates to reflect current consumer behavior; consent involves transparent governance; interoperability enables cross-platform integration via a secure identity spine. As marketing shifts toward agentic advertising, flawed data accelerates bad decisions. The piece emphasizes continuous data validation, deduplication, and context to keep models reliable, and notes that deterministic signals require ongoing verification. It also asserts governance should be embedded in data platforms to meet privacy laws, and that human oversight remains essential in turning automated insights into actionable strategies. It concludes by praising Experian as a source of accurate, privacy-first data and urges building data principles around transparency and trust.
AI Exposes Poor Marketing Data Quality
The article argues that widespread adoption of AI in marketing amplifies the risks of poor data quality, since models produce confident outputs regardless of data reliability. Subu Desaraju — who leads commercial and operations at iceDQ and previously worked at Tempur-Pedic, Digitas, WPP and MRM — advises focusing data checks at the source and outlines two practical frameworks: trace a campaign backward to find gaps, and build solutions across people, process, and tools. The piece warns that consumer-facing industries are especially lax about data systems compared with regulated sectors, and cites Gartner’s estimate that poor data quality costs organizations roughly $15 million per year.
Trust Must Drive Your Data Strategy
In a MarTech contributed essay published June 24, 2026, Jay Mandel argues that the advertising and data economy is built on an extraction-first architecture that treats people as raw material rather than participants. He contends technical fixes (cleanrooms, CDPs, brokers) cannot fully address the problem because the foundational incentives prioritize signal extraction over human understanding. Mandel outlines harms from 'dirty data'—price discrimination, biased hiring automation, malicious health advertising, and predatory financial targeting—and cites legal scholar Cass Sunstein to distinguish legitimate influence from algorithmic manipulation. He advocates shifting toward transparency, specific consent, clear chain-of-custody and a 'clean data' model in which people can verify and control their data, claiming this approach yields better compliance, lower breach liability, and durable trust.
