    Contacts being duplicated after CSV file upload

    Minna Pacanowski

      We have noticed that contacts are duplicated in Marketo and SF when we upload a CSV list of contacts to invite to an event.


      Some of the contacts will already be in our database (both in SF and Marketo), however, Marketo will sometimes duplicate the contacts which then leads to a duplicate also being created in SF.


      Is there a way to prevent this from happening going forward, so that existing contacts are not duplicated?
