Email Identity File

Start With Data You Can Trust. And Build Everything Else On It.

Every enterprise data strategy, no matter how ambitious, rests on a deceptively simple question:

Can I trust this data?

AtData’s Email Identity File was built to make the answer clear. With verified links between real people, their email addresses, and their physical locations, this is not just a reference dataset — it’s a living foundation for confident decisions, cleaner systems, and smarter growth.

The Most Trusted Data in the Room

You’re not here for more data, you’re here for better data. Data that can do more than fill a column. Data that stands up to scrutiny, scales with complexity, and gives every downstream process a head start. This is where AtData excels.

Our Email Identity File connects millions of unique, deliverable email addresses with corresponding names and postal addresses, spanning billions of records in total. These are not stitched-together assumptions. They’re validated connections, pulled from a multisourced network built over decades — verified, standardized, and structured to support serious use cases.

What’s Included

AtData’s name, postal, and email file is built to integrate easily into your systems, delivering the scale and structure needed to support high-volume, high-stakes initiatives.

• 2.4+ billion total records
• Multisourced, verified linkages between emails, names, and mailing addresses
• Standardized, structured format for enterprise use

This is your connective tissue. For identity graphs, data lakes, enrichment platforms, or custom apps. Whether you’re working within a CDP or launching a product that hinges on accurate identity, this file is your foundation.

How It’s Used

No two use cases are identical. But the need for reliable identity doesn’t change. The Email Identity File supports a range of business-critical initiatives:

• Identity Resolution and Unification

  Eliminate duplicates and connect fragmented records. Link identities confidently across devices, systems, and sessions using verified email + name + postal pairings.

• CRM and CDP Enrichment

  Fill in what’s missing. Validate what’s already there. Make your customer data more actionable, more complete, and more future-proof.

• Audience Segmentation and Activation

  Use real, known individuals as the foundation of high-performing marketing audiences. No modeled records, no synthetic identities, just clean, actionable data.

• Analytics and Attribution

  Improve match rates between platforms and datasets by grounding analysis in confirmed identity. Know who took what action, not just what happened.

• Model Development

  Give your machine learning models the inputs they need to classify accurately, predict behavior, or assess risk with a foundation of clean and complete identity data.

Why It Delivers Real Value

There’s no shortage of data vendors promising reach or volume. What sets AtData apart is the integrity of our data, and the infrastructure we’ve built around it.

• Independently verified and continually maintained
• Drawn from a diverse network of opt-in and permissioned sources
• Rooted in over two decades of email-centric data expertise
• Structured for direct use in identity graphs, modeling workflows, and enrichment tools

This isn’t reference data. This is live, usable identity infrastructure that adapts to your needs and evolves with your strategies.

Built for Flexibility, Ready for Scale

Most “contact files” are frozen snapshots, outdated before they reach your hands. AtData’s Email Identity File is different. It reflects ongoing activity and real-world usage, curated from billions of monthly signals and refined through our proprietary validation pipelines. What you get isn’t just accurate today — it’s defensible tomorrow.

That means less second-guessing. Fewer blind spots. More clarity across systems.

Whether you’re enriching a CRM or training a model, this file adapts to your use case. With broad coverage, structured formatting, and field-level transparency, it’s ready to support:

• Enterprise-scale identity initiatives
• SaaS platform enrichment and onboarding
• Customer journey stitching and lifetime value modeling
• Custom applications and analytics workflows
• Multi-channel marketing and measurement strategies

The Data Underneath It All

Even the most advanced tools, platforms, and models depend on something simple: knowing who you’re dealing with. That’s the power of AtData’s Email Identity File.

You get scale. You get structure. But most importantly, you get a truth you can act on.
