What are External Email Notifications?
External Email Notifications let you email test plan updates to people outside your workspace (for example, clients, managers, or executives). Recipients don’t need a TestCollab login—updates are delivered directly to their inbox
How to add external email recipients
From the Project General Settings page, administrators can add external email recipients who will receive test plan related notifications automatically.
