Make the Gmail Unread Count More Visible in Tabs
To move the unread count forward in the Gmail page title and make it visible in background tabs or collapsed and minimized windows:
In your Gmail inbox screen, select Settings (gear icon). Select See all settings. Select the Advanced tab. In the Unread message icon section, select Enable, then select Save Changes. Now, your Gmail Chrome tab will display the number of unread messages you currently have.
