Which two methods can help resolve issues with duplicate contacts effectively?

Employing an AppExchange tool for data management is an effective method for resolving issues with duplicate contacts due to the specialized features and functionalities these applications typically possess. Many of these tools are designed specifically to handle data quality issues, including deduplication, by allowing users to import, clean, and manage their data seamlessly. They provide advanced algorithms and user-friendly interfaces that can efficiently identify and consolidate duplicate contacts, making the process faster and more reliable compared to manual methods or basic implementations.

While other options may provide solutions for managing duplicates, they might not offer the same level of ease or effectiveness. For example, writing a Batch Apex class would require significant programming knowledge and maintenance. Implementing duplicate management within the organization is a more manual approach and may not be as comprehensive as third-party tools. Assigning new contacts to a data quality team, while useful for oversight, does not actively resolve duplicates and can be time-consuming and prone to human error. Utilizing an AppExchange tool integrates sophisticated capabilities automatically, providing a more streamlined resolution process for duplicate contact management.
