List of people and voter files

If I import a list of people to invite to an event now and later add a voter file, will the people in my list be connected with their appropriate voter file information?

Official response from

Ordinarily, people imported from a voter file (whether it's a custom voter file import or from NationBuilder's Election Center) will not automatically merge with the existing people in your database. The exception to this rule is in the case of voter files that include email addresses (ex: Los Angeles County, California, voter file), in which case people would be automatically be merged based on matching email addresses.

Luckily, NationBuilder makes it easy to merge duplicates following a large import. 

Once a day, NationBuilder will automatically group all the profiles that appear to be duplicates and allow you to click through on the potential matches to easily accept or reject a merger. You can merge a person for whom you've imported two different email addresses from two different sources and who also follows you on Twitter, for example.

More information is available on how to merge duplicate profiles.
