 # Troubleshooting
 
-### Email Server setup
-Email notifications are customizable,Admins can `enable` or `disable` email notifications on `Global Variables` setup.
-Inorder to proceed with email notifications admin has to store the email server (smtp server or a dedicated e-mail) credentials as part of `Global Variables`.
+Please feel free to reach out and to create a [GitHub issue](https://github.com/GoogleCloudPlatform/rad-lab/issues) in case of any issues or concerns.
 
-`MAIL SERVER EMAIL` will be stored in `firestore` and `MAIL SERVER PASSWORD` will be securly stored on `Google Secret Manager`
+## Email Notifications
+You can optionally enable RAD Lab notification for deployment events. This includes deployment creations, updates, and deletions.
+
+If enabled, the following users/groups (defined in the module's Terraform variables) will receive email notifications:
+- The individual taking the action
+- `trusted_users`
+- `trusted_groups`
+- `owner_users`
+- `owner_groups`
+
+Currently only sending via gmail is supported. It is recommended to [create a new gmail address](https://support.google.com/mail/answer/56256?hl=en) for this purpose only. Do **not** enable two factor authentication (2FA) on this account. You will then provide this email and its password to RAD Lab UI via the `Global Variables` setup.
+
+The email address will be store in Firestore, and email password will be securely stored in Google's [Secret Manager](https://cloud.google.com/secret-manager)
