Contact Creation/List Upload in SFDC Causes Marketo to Create Dupe Leads
We recently discovered an issue. When uploading a list of Contacts in SFDC with Data Import Wizard, or when Contacts are pulled into SFDC from ZoomInfo, Marketo then creates a duplicate Lead record.
How do we prevent this? I understand we likely should do all list uploads through Marketo, but how do we prevent this from happening when a Contact is pulled into SFDC from ZoomInfo?
