What Are Data Appends and Why They Matter

Data Appends

Data Appends connect incomplete, outdated, or anonymous records to verified consumer information, creating a complete and accurate profile for every contact. This gives your marketing, analytics, and customer systems the verified foundation they need to reach real people across every channel.

With Xcelerated, you gain access to more than 300 million verified consumer profiles built and refined through years of continuous data enrichment and behavioral tracking. Our clients typically see more than 40 percent additional verified contacts compared to standard append providers.

Types of Data Appends

Xcelerated’s Data Append solutions fill in the missing details that turn anonymous records into verified consumer profiles. Each append type is validated and layered through our Consumer Identity Graph for accuracy and scale.

Email Append

Email Appends That Reconnect You With Real Customers

Add verified primary and alternate email addresses to your customer or prospect records. Our layered data sources and validation process ensure active, deliverable inboxes — not dead addresses.
Alternate emails extend reach and reactivation opportunities, helping brands recover lost connections and drive higher engagement rates.

Reverse Appends That Uncover Full Consumer Identities

Reverse Append

Start with a single data point — like a phone number or email — and reveal the complete consumer identity including name, address, and verified contact details.

Reverse appends are ideal for CRM enrichment, customer lookup, lead verification, and fraud prevention initiatives.

At its core, Northbeam is a data company. Which is why I trust their models and attribution over anyone else. I know when I look at their data I get an honest look at our performance. Good or bad.
