Run the signature within the Signature Tester.

The Signatures Tester is an interactive tool that tests the deployment of your email signatures.

This shows you how your signatures are processed and applied to emails based on the settings you have specified.

The Tester simulates sending an email from your chosen sender to your chosen recipient, and checks any applied signature rules for each enabled signature in the order they are stored. It then provides a breakdown of how the rules affect the deployment of your signatures.

How to access the Signature Tester:
From the menu sidebar, select Signatures Tester.
