Know more about your customers.

First-party data is invaluable. It is also inherently incomplete.

It can tell you what a customer bought, clicked, opened, submitted, or abandoned inside your environment. It rarely tells you enough about who that person is, how their circumstances differ, or whether their behavior with your brand reflects their broader activity.

AtData uses email as a persistent identity anchor to add demographic, household, behavioral, purchase, and activity intelligence to the customer records you already have.

The result is not simply more data. It is more context for deciding who to prioritize, how to engage them, and what to do next.


More data is not the same as more understanding.

Most organizations already have enormous amounts of customer data. The problem is that much of it describes transactions rather than people.

Two customers can make the same purchase and have very different incomes, households, interests, life stages, and future needs. Two subscribers who have stopped opening your emails may look equally inactive even though one remains highly active elsewhere and the other has largely abandoned the address.

Without additional context, systems are forced to infer.

AtData enriches known identities with attributes and behavioral signals that help organizations move from what happened toward why it may matter.

Add context your first-party data can’t see.

Understand who they are – Add foundational customer context.

Append demographic and lifestyle attributes that help organizations distinguish customers beyond their transactions and campaign histories. These attributes can improve segmentation, audience analysis, personalization, modeling, and customer strategy.

Available data includes attributes such as:

Explore Demographic Append

Understand what matters to them – Move beyond broad demographic assumptions.

People with similar demographic profiles do not necessarily behave alike. AtData can add interests, lifestyle indicators, and purchase-category data that provide another layer of customer context. AtData’s purchase-category data connects observed purchasing behavior to known email identities rather than relying solely on abstract audience assumptions.

Available intelligence includes categories spanning:

Explore Interests

Understand how active they are – Your engagement data shows their relationship with you. Network activity adds another perspective.

A customer who has stopped responding to your organization may not actually be inactive. AtData’s activity network processes more than 150 billion deterministic signals each month, providing broader context about how email identities are being used across the network. This makes it possible to distinguish between an identity that is truly dormant and one that simply is not engaging with you right now.

Activity intelligence helps identify:

Activity-Backed Identity

Understand relative customer quality – Not every valid identity carries equal opportunity.

AtData’s machine-learning-based Quality Score assigns an email address a 0–10 relative engagement score using signals such as activity, digital footprint, observed commerce, and engagement patterns. It is another way to move beyond simple presence and toward relative customer potential.

Organizations use this additional signal to:
