Please see our help documentation for a full description of the service.

Email address is the primary data point, but we also use Name and Address information to facilitate matches. Each social network is different in how they allow matches and they change their rules pretty regularly. How they allow access and limit searching has a direct impact on match rates and quality of results.

The user's settings have an impact on the results across all networks. The more public a constituent's profile is, the easier it is for us to locate data.  

Of the major networks, LinkedIn and Facebook are the most strict as far as allowing their data to be searched. Twitter is the easiest network to find matches.
