While exporting to Salesforce, contact information mapping will be done from SalesIntel to Salesforce based on the email address of the contact. If duplicate addresses are found, the user will be prompted with a ‘Duplicate data’ pop up with options to update all fields, update only the empty fields or not to export the duplicates.
Now, the user can choose an appropriate action.
The action will be applicable to all the duplicate leads found in the export batch. You’ll not be able to take selective actions for each contact.
