What Is Data Appending?

Data Appending is the process of enhancing your existing customer or business database by adding missing details such as email addresses, phone numbers, postal addresses, social media profiles, demographic and firmographic attributes, and more. By bridging these data gaps, we help you gain a 360-degree view of your audience.
