# Duplicate Cases - Email to Case

**Email-to-Case Duplicate Management** helps avoid clutter when multiple emails create duplicate cases for the same issue. It detects and merges duplicates, consolidates information, and keeps case handling efficient and consistent.

* **Duplicate Detection** – [Configures how the system identifies potential duplicate cases (e.g., rules, filters, and thresholds).](https://help.delpha.io/delpha-for-salesforce/use-cases-setup/duplicate-cases-email-to-case/duplicate-detection)
* **Duplicate Merge** – [Defines how duplicates are resolved, including merge strategies, parent assignment, and field inheritance.](https://help.delpha.io/delpha-for-salesforce/use-cases-setup/duplicate-cases-email-to-case/duplicate-merge)
* **Run the initial assessment** – [Executes a first pass of the duplicate detection process to evaluate existing cases against the configured rules](https://help.delpha.io/delpha-for-salesforce/use-cases-setup/duplicate-cases-email-to-case/run-the-initial-assessment).
