Which feature of Salesforce can be used for efficient monitoring of duplicate records?

Salesforce Duplicate Management is designed to efficiently monitor and manage duplicate records within the Salesforce ecosystem. This feature allows organizations to define rules that identify potential duplicate records based on specific criteria, such as email addresses or names. By leveraging matching rules and duplicate rules, users can control how duplicates are identified and subsequently handled, such as preventing the creation of duplicates or alerting users when a potential duplicate is detected.

This functionality is essential for maintaining data integrity, improving data quality, and ensuring that users have accurate information for reporting and interactions. In contrast, options like the Data Loader and Data Import Wizard focus more on data manipulation and importing processes rather than ongoing monitoring of duplicates. NPSP Settings primarily provides configuration specific to the Nonprofit Success Pack but does not directly address duplicate management in the same robust manner as Salesforce Duplicate Management does.
