    Avoiding Duplicates

    Eitan Rapps

      We have 2 main sources of lead creation - leads coming from Salesforce, and leads being uploaded to Marketo via List Import.


      Sometimes we are finding that duplicates are being created when email@gmail.com was originally created in Salesforce, and synced over, as well as when it was imported via list. My understanding is that if the way an email address enters into Marketo in 2 different ways (Salesforce vs. List Import for example), Marketo will not keep the email and overwrite everything else.


      Is there any way to prevent this? Can I make sure that when an existing email address, which came from Salesforce, is later added again through List Import, that a duplicate record isn't created?
