What’s changing 
We’re adding a new “External” label to email threads that include recipients outside your organization. This adds to the existing external recipient warning banner, which is displayed when responding to emails sent from outside of your organization. 


The “External” label will be visible on Gmail on the web and Android devices. We will provide an update when this feature becomes available on iOS. 




The external label and warning banner appears when interacting with individuals outside the domain.


Who’s impacted 
Admins and end users 


Why it’s important 
The “External” label and the reply warning banner and label are helpful reminders for users to treat external messages with caution. This can help avoid unintentionally sharing confidential information with recipients outside of their organization. 


Additional details 
Secondary and alias domains are exempted from being labeled as “External”. 


Getting started 
  • Admins: Visit the Help Center to learn more about turning external recipient warnings on or off in Gmail. Note: This setting controls both the “External” label and warning banner. 

  • End users: No action required. When enabled by your admin, you'll see "External" label and warning banner when interacting with or replying to email threads with recipients outside your organization or contacts.
