Google Workspace offers an Image URL patterns allowlist feature that schools can use to better control what external images are displayed in student and staff emails. While this setting is currently turned on in many environments, it often remains unused due to missing configurations.

If your school wants to block or allow images from specific domains—such as approved curriculum providers or internal resources—you must define those URL patterns. Doing so boosts email safety by preventing unwanted or potentially harmful image loads while maintaining visibility for trusted content.

At Get Set Tech, we help schools configure smart, secure Google Workspace policies that improve classroom experiences and keep everyone protected.
