Google’s Collaborative Inbox can be used by your team to collaborate on messages received by a Google Group.
With Google Groups, all members in your group can see inquiries sent to your support email address. Once inquiries are received, team members can assign each other tasks, categorize topics with labels, and mark topics as resolved. This allows your group to add structure to your support efforts.
Group managers can learn how to turn on this feature by visiting Google’s support website.
