Latest / The CMO Podcast with Fexingo: Marketing Leadership, Budgets, and Executive Strategy / How CMOs Use Zero-Party Data to Fix Personalization
Transcript
- Lucas: If you ask a customer what they want, and they actually tell you, that's worth more than anything you could infer from their browsing history. Luna: That sounds almost too simple. But I'm guessing there's a catch. Lucas: The catch is that most brands don't ask. They track, they model, they infer — and then they get it wrong. But there's a growing group of CMOs flipping that script. Luna: Alright, I'm intrigued. What are they doing differently? Lucas: They're turning to what the industry now calls zero-party data. That's data a customer hands over intentionally — through a quiz, a preference center, or a direct conversation. Not observed, not purchased. Given. Luna: And before we go deeper — Lucas, you know I'm a fan of what you're doing with these conversations. If this show has given you a new idea or a fresh way to think about your own marketing, a couple of dollars a month is genuinely what keeps these going. You can find us at buy me a coffee dot com slash fexingo. Lucas: That's the kind of support that keeps us ad-free and independent. And honestly, it's the same spirit as the topic today — people sharing what they value, willingly. Luna: Okay, so zero-party data. How is that different from first-party data, which we hear about all the time? Lucas: First-party data is anything you collect from your own channels — purchase history, website behavior, app usage. It's still observational. Zero-party data is explicit: the customer tells you their skin type, their budget, their communication preferences. It's like the difference between watching someone browse a menu and asking them what they'd like to order. Luna: I love that analogy. And in a privacy-first world, it's got to be a safer bet. Lucas: Exactly. With third-party cookies crumbling and regulations tightening, relying on inferred data is getting riskier and less effective. Zero-party data is built on consent and transparency — it's the kind of data that actually strengthens trust instead of eroding it. Luna: So where are you seeing CMOs actually apply this in a way that moves the needle? Lucas: One of the clearest examples is in beauty. Think of a brand like Sephora — they've been doing this for years with their Color IQ quiz. You answer a few questions, and they recommend foundation shades that actually match your skin. That's zero-party data driving personalization. Luna: Right, and that's not just a one-time thing. They can use that data to tailor emails, product recommendations, even in-store experiences. Lucas: Exactly. And it goes beyond beauty. I was reading about a financial app that asks new users to set their savings goals and risk tolerance through a simple slider interface. That data feeds everything from their dashboard to their notification strategy. It's personalization without the creep factor. Luna: That's a great point. Because when a brand asks me what I want, I feel respected. When they just assume, I feel watched. Lucas: And that's the shift. CMOs are realizing that relevance isn't just about accuracy — it's about respect. Zero-party data delivers both. Luna: So how do you actually collect this data without making it feel like a chore? Because quizzes can be annoying. Lucas: That's the million-dollar question. The key is to make it valuable for the customer. Sephora's quiz isn't just a data grab — it solves a problem: finding the right shade. The financial app's questionnaire helps users clarify their goals. The data is a byproduct of help, not a demand. Luna: So the exchange has to be fair. You give me something useful, I give you my preferences. Lucas: Exactly. And the best CMOs are also thinking about the ongoing relationship. It's not just a one-time quiz. Preference centers are becoming a standard part of the customer experience — an always-on place where people can update their choices, refine their interests, and control how they're communicated with. Luna: And that has to help with retention. If someone feels in control, they're less likely to ghost you. Lucas: Absolutely. There's a reason the loyalty world has embraced this. When a customer tells you they're interested in, say, sustainable products, and you send them relevant content about that, they feel understood. That's loyalty you can't buy with points alone. Luna: Now, does this mean we should all be ripping out our analytics dashboards? Probably not. Lucas: No, of course not. Zero-party data is additive, not a replacement. You still need behavioral data to understand the full picture. But it's the layer that adds explicit intent — and that's incredibly powerful for personalization engines. Luna: What about the tech side? Are there tools that make this easier? I'm thinking about the CDPs and all that. Lucas: Customer data platforms are becoming the backbone for this. They can unify both zero-party and first-party data into a single profile. But the real challenge isn't the tech — it's the culture. You need to get comfortable asking customers for information and then using it responsibly. Luna: Responsibly meaning — what? Don't be creepy? Lucas: Partly. But also transparently. If you're collecting data through a quiz, tell people what you'll use it for. And give them control over it. That's what builds trust, and trust is the ultimate currency in marketing right now. Luna: So, is zero-party data the answer to the cookie apocalypse? Lucas: I think it's a huge part of it. But it's not a silver bullet. You still need to earn the right to ask. No one's going to fill out a 20-question survey for a brand they don't care about. Luna: So it's kind of a virtuous cycle. The more you engage, the more you learn, and the better you can serve them. Lucas: That's the dream. And honestly, it's a more honest form of marketing. You're not tricking anyone into giving you data. You're having a conversation. Luna: A conversation that ends with better products, better messaging, and customers who actually feel heard. Lucas: Yeah. And I think that's where we're headed. The CMOs who figure this out now will have a serious advantage as the old tracking methods fade. Luna: So what's the one thing you'd tell a CMO who's still on the fence? Lucas: Start small. Pick one area of the customer journey where you can ask a simple, valuable question — and start collecting. You'll be surprised at how willing people are to share when they see the benefit. Luna: And if you're listening, maybe that question is the beginning of a whole new relationship with your customers. Lucas: Exactly. Thanks for joining us on this one. We'll see you next time.
