Import Options

Control how CSV data updates your contact database by selecting one of three import behaviors:
  • Only Create New Contacts: Creates new contacts from email IDs not found in your Contact database. Ignores existing email IDs.
  • Only Update Existing Contacts: Updates existing contacts with new data from your CSV. Only non-blank CSV cells update existing values.
  • Create and Update Existing Contacts: Combines both behaviors above. Updates existing email ID contacts with non-blank values and creates new contacts from new email IDs.
Override the default update behavior with these options:
  • Update Empty Fields Only: Update only empty contact fields during the import process, leaving populated fields unchanged.
  • Overwrite with Blank Values: Replace existing Inflection data with blank values from the CSV.
Warning: Enabling this option will result in the removal of existing contact properties if they are left blank in the CSV. Please exercise caution when enabling this option.
