If I import a list two times will it create duplicate contacts?

Last updated: December 13, 2016

HubSpot will deduplicate contacts based off of email address.

  • Importing the same list twice will only result in one contact created per email address.
  • Please note our import function will update contacts' properties with newer information. It will also ignore any blank rows or columns your .csv file contains.
