Options for managing spam messages

We recommend that users in your organization use Gmail to review and manage spam messages they receive.

Use Gmail to manage spam messages

We recommend users in your organization manage spam with any of these Gmail apps:

• Gmail Android
• Gmail for iPad and iPhone
• Gmail web

Use these apps to identify and mark inbox messages as spam. This trains Gmail to mark similar messages as spam. You can also identify messages falsely marked as spam and move those messages to the inbox. This trains Gmail to identify similar messages as valid messages.

To let your users manage spam with Gmail web and mobile apps:

• In your Google Admin console, delete any Non-Gmail mailbox setting so that users can open Gmail web and mobile apps. Find this setting in AppsGoogle WorkspaceGmailRouting.
• Turn off any mail delivery settings that route mail to an external mail server. Learn more about email routing and delivery settings.
• Instruct users in your organization to use Gmail to manage spam messages.

Learn what administrators can do when Gmail incorrectly marks some or all of your external incoming email as spam.

Other ways to manage spam

Although we recommend using Gmail to manage spam, one of these other methods might be more appropriate for your organization. These methods are intended for administrators only.

Route all mail to a legacy mail server

Route all messages to your legacy mail server with routing settings. The legacy server identifies spam messages, and users view and manage spam with their legacy email app. Learn more about email routing and delivery settings

To improve spam identification, turn on spam and phishy headers in Gmail routing rules. If this setting is off, the legacy mail server might miss some spam messages.

Learn more about adding spam headers to routing rules.

Groups message moderation

Turn on Groups message moderation so specified group members can review potential spam messages before they’re delivered to users’ inboxes. Moderators get regular reports that include spam messages from the moderation queue.

Learn about message moderation in Groups.

Send messages to quarantine review

Quarantine possible spam messages sent to and from your organization so they can be reviewed before being delivered. Messages are sent to the admin quarantine, where administrators determine what action to take on each message.
