As a Groups administrator, you can add an identifying word or phrase to the end of email addresses of groups created in the Google Groups app at groups.google.com.
For example, if you specify the suffix -user-created, and a user creates the group firstname.lastname@example.org, the group email address is email@example.com.
Why add a suffix
Add a suffix to user-created groups if you want to:
- Differentiate between groups created in the Admin console and in Google Groups. The suffix is applied only to groups created in Google Groups (at groups.google.com).
- Ensure users don’t create groups with email addresses that you or other administrators might need to use, such as “all@your_domain.com”.
Add a suffix to user-created group email addresses
The suffix you specify here is added to email addresses of any new groups created at the Google Groups app. If you change to a different suffix, new groups receive the new suffix while existing groups keep their original suffix.
Tip: To make the suffix stand out in your Admin console's Groups list, add a hyphen at the beginning of the suffix.
