How does the Untitled ID Tag work?
The Untitled ID Tag matches anonymous visitors to real identities using our Identity Graph, built from 300+ million people-based records and enriched with first-party, third-party, and real-time data. We fill in details like name, contact info, job title, and demographics so you can turn anonymous traffic into actionable leads.
What is an Identity Graph?
An identity graph is a vast interrelated and networked structure of data that connects digital identifiers, like hashed emails, device IDs, and IP addresses, to real people. Untitled’s graph combines first-party, third-party, and co-op data to link U.S. adults to contact details, demographics, and firmographics, helping you identify and enrich website visitors with precision.
Is the Untitled ID Tag compliant with privacy regulations?
Yes. The Untitled ID Tag operates using first-party data from users who’ve interacted with your site. To stay compliant, ensure your privacy policy discloses data collection for marketing and includes an opt-out option. Visit our compliance page for full details.
Can I email these hidden website visitors?
Yes, but you must follow CAN-SPAM guidelines. That means including an unsubscribe link in every email and honoring opt-out requests. Most email platforms handle this automatically with built-in suppression lists. Learn more about compliance in our policy center.
