mail address

Identify the most active and deliverable postal address and email address for an individual.

Over 250 million adults in the United States with multiple emails tied to various postal addresses results in over 1 billion combinations of emails and postal addresses. By NCOA'ing our postal addresses and validating our emails, we can identify current email and postal matches to filter out any invalid records.


Acquire permission-based data compiled by our trusted partner network.

Our partners receive a name, postal and email address as part of their registration process. Data submitted through web forms, surveys, subscription databases, sweepstakes, etc. are recorded with a time-stamp, IP address, and the original source. 

Email and web signals

Update database with email and web signals

We continually aggregate the history, behavior and linking of email data to generate an ever-expanding database of over 2 billion email activity signals monthly, encompassing 360 million unique emails and 4 million unique domains.
online behavioral

Multi-source data from top-tier aggregators, the census, online behavioral and online purchase intent triggers.

We collect billions of data points to provide customers with valuable demographic and household data on 80% of all US emails.

Filter tokens

Sort, normalize, filter and connect the dots across individual identities to build an accurate picture of the people behind their email addresses.

Leveraging AtData’s identity graph, we use advanced algorithms and machine learning to package data points and match them to the appropriate email address, postal address, cookie or mobile advertising ID. We only match data to a point of contact when we are at least 90% confident about the association.
