Experian Acquires Email Identity Specialist AtData to Strengthen Digital Identity and Signal Intelligence

Experian, the global information services company best known for credit reporting and consumer data insights, has agreed to acquire AtData, a specialist in email identity resolution and consumer signal intelligence. The acquisition is part of Experian’s strategy to expand its data and identity solutions stack — enabling more accurate customer identification, enhanced fraud detection and improved personalised engagement across digital channels. AtData’s proprietary email-based identity graph, which maps user behaviour and authentication signals across devices and platforms, complements Experian’s existing suite of identity verification, risk scoring and marketing intelligence products.

In a digital economy where email remains a core channel for account creation, login and first-party communication, strengthening email identity capabilities offers significant advantages for enterprises seeking to reduce fraud, improve onboarding and deliver relevant experiences across CRM, loyalty and digital marketing applications. Experian says the combined offering will help clients navigate increasing privacy regulations while leveraging richer identity signals in a cookieless world.

What AtData Brings to Experian

1. Email Identity Resolution

AtData’s core strength lies in its email identity graph, which connects email addresses with device signals, behavioural patterns and cross-platform attributes. This enables brands to:

• Resolve identities across sessions and channels
• Reduce fragmentation in CRM and engagement systems
• Build persistent identity profiles beyond cookies or device IDs

This capability is increasingly critical in an era where traditional identifiers such as cookies are being deprecated and digital touchpoints are proliferating.

2. Signal Intelligence for Engagement

Beyond resolution, AtData provides signal enrichment that helps enterprises understand how customers interact across digital touchpoints — from email opens and link clicks to login behaviour and mobile usage. This data can enhance:

• Personalised marketing campaigns
• Real-time engagement triggers
• Loyalty and retention strategies
• Adaptive authentication

3. Risk and Fraud Mitigation

Email signals and identity correlations add an additional layer of insight for fraud and risk teams. By combining AtData’s technology with Experian’s risk scoring and identity verification tools, businesses can improve:

• Account takeover detection
• Synthetic identity identification
• Behavioural risk scoring
• Anomaly detection in login or transaction flows

This is particularly valuable in financial services, ecommerce, digital banking and social platforms where fraudulent activity continues to evolve.

Why This Matters

1. Identity in a Cookieless Era

As privacy regulations tighten and third-party cookies are phased out, enterprises are seeking first-party identity signals that are persistent, privacy-compliant and actionable. Email remains one of the most stable and widely accepted identifiers for consumer login and engagement — making email identity graphs a strategic asset for both marketing and risk use cases.

2. Growth in Digital Fraud and Credential Abuse

Cybersecurity threats, including credential stuffing, account takeovers and synthetic identity fraud, have risen sharply in recent years. Strengthening identity resolution helps firms differentiate genuine user behaviour from malicious patterns, reducing losses and improving trust.

3. Convergence of Marketing and Risk Data

Modern customer experience strategies blur the lines between risk management and engagement. By combining identity resolution with risk scoring, enterprises can personalise experiences while maintaining security, compliance and risk-aware controls at every touchpoint.

Market and Competitive Context

Experian competes with other identity and data platform providers — including TransUnion, Equifax, Neustar, LiveRamp and First-party Data Platforms — in delivering identity resolution and engagement signals. The acquisition of AtData enhances Experian’s ability to compete by integrating high-value email identity intelligence into a broader suite of risk, compliance, and analytics products.

For email-centric data businesses and martech ecosystems, the trend toward stronger identity graphs reflects a broader push for privacy-safe, persistent consumer profiles that can power personalisation without compromising regulatory compliance.
