Manage spam messages

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

Message Center deprecation: Message Center is a web console where Gmail users view and manage spam email messages. Starting October 2019, Message Center and Quarantine Summary will be deprecated. Until deprecation is complete, these features might be available for some G Suite users. At some point after October, Message Center will no longer be available and new Quarantine Summary emails will no longer be delivered. You won’t receive a notice before this happens. We recommend that administrators start using the spam management methods described in this article.
 
Answers to common questions are in More about Message Center deprecation.

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:

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.

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.

Is mail delivery affected?

No. Although we’re changing the way users view and manage spam, we’re not changing the way valid emails are delivered to your users.

Can I continue to send mail through Gmail to my on-premises server?

Yes. You can continue to use Gmail for spam and antivirus filtering, and then route mail to an on-premises mail server.

Can I review spam with methods other than Gmail?

Yes. G Suite supports several ways for administrators to manage spam. However, we recommend that your users view and manage spam messages only with Gmail.

Can I use Gmail web and mobile apps as the spam quarantine only, so that messages marked "not-spam" are routed on-premise automatically?

No. This is not recommended and not supported. Messages marked as "not-spam" in Gmail web and mobile apps are put into the Gmail Inbox automatically. Routing rules to deliver messages on-premise are not triggered in this scenario.
