Zero-Party Data (Customer-Volunteered Data)
Information customers hand you directly and willingly — the clearest signal of what they actually want.
…A short preference quiz can generate zero-party data that makes every follow-up email more relevant than broad segmentation ever could.…
What it means
Zero-party data is data that a customer explicitly and proactively shares with a brand, such as choices made in a preference center or answers to an interactive quiz.
Unlike behavior that has to be inferred, zero-party data states intent directly — a customer telling you they prefer email over text, or that they’re shopping for a gift, removes the guesswork entirely.
Removes the guesswork
Customers tell you their preferences directly instead of you inferring them from behavior.
Builds trust through transparency
Customers know exactly what they’ve shared and why, which supports a stronger brand relationship.
Sharpens personalization
Explicit preferences lead to more relevant offers and messaging than inferred data alone.
DNA's Take: We design quizzes, preference centers, and interactive content specifically to capture zero-party data, turning it into sharper segmentation and messaging for every client.
