AtData — email address intelligence

Turn an email address into a stronger identity signal

Built on more than 25 years of email-centric identity history and billions of monthly activity signals, AtData helps businesses make more confident decisions from acquisition and onboarding through engagement, transaction and retention. As part of Experian, AtData brings deep email intelligence to a broader ecosystem of consumer data, analytics and decisioning capabilities, helping organizations identify, authenticate and engage customers with greater confidence.

We acquired AtData in February 2026, extending our identity capabilities with real-time email intelligence on more than 10 billion email addresses worldwide.
Email intelligence uses the history, activity and associated attributes of an email address to produce insight about the identity behind it. Depending on the use case, that intelligence can help determine whether an email is valid, connect related identity elements, enrich a customer profile for marketing, or reveal potential risk.
AtData can identify invalid, inactive, disposable and potentially harmful email addresses before they enter a database or campaign. It can also help update and complete records through identity matching and data enrichment, improving the accuracy and usefulness of first-party customer data.
