Move email to the right Gmail tabs to control email flow

One of the great things about Gmail is its tabbed interface that sorts messages into multiple inboxes (e.g., Primary, Promotions, Social, etc.). You can drag messages between these inboxes to control which ones generate new mail notifications and which ones simply accumulate in another tab. This can be useful for avoiding feeling overwhelmed by your email, and for safely tuning out unfamiliar senders.
