Is the data you’re using in marketing actually real—or just a spreadsheet full of guesses? In this episode of Mostly Marketing with Matt Wilson, we dig into the world of data-driven marketing with Matt Spiegel, EVP of True Audience Growth Strategy at TransUnion. From programmatic campaigns to identity resolution, we break down how to tell the difference between good and bad data—and why testing is the only way to know what actually works. 

We also explore the future of data, AI, and personalization, and how marketers can navigate complex ecosystems while reaching the right people at the right time. Whether you’re an agency pro or just curious about the inner workings of modern marketing, this conversation is full of insights, practical advice, and a few laughs along the way.
