How does the Import Wizard differ from the Data Loader?

The Import Wizard prevents duplicates by specific criteria, which is a critical function for maintaining data integrity within Salesforce Marketing Cloud. When importing data, the Import Wizard provides options to specify how duplicate records should be handled. This ensures that existing data is not overwritten or unnecessarily duplicated. The ability to set criteria for identifying duplicates is particularly important when managing subscriber lists or customer data, as it helps maintain a clean and accurate database.

While there are other tools like the Data Loader that can also handle imports, they typically do not offer the same user-friendly interface for duplicate management that the Import Wizard provides. The other options do not accurately represent the capabilities of the Import Wizard. For instance, it does not handle record limits in the same way as the Data Loader, nor does it offer functionality for exporting data, and it is not restricted to use solely for transactional messages.
