# Run the initial assessment

To run your first check for existing duplicate cases, simply click the **Launch Assessment** button at the top of the Email-to-Case settings.

{% hint style="warning" %}

* If the button is not visible, it means the initial assessment has already been executed.
* If you change any setting that affects the analysis scope (such as [Assessment Period](/delpha-for-salesforce/use-cases-setup/duplicate-cases-email-to-case/duplicate-detection.md#assessment-period-days) or [Case Filters](/delpha-for-salesforce/use-cases-setup/duplicate-cases-email-to-case/duplicate-detection.md#case-filters)), you’ll be prompted to reassess the cases when saving (Save & re-assess Cases).
