Use flags to prioritize your messages.
Suppose you have a collection of 300 messages in your Inbox. Or, perhaps you've neatly filed everything, only to wonder "do I need to act on one of those messages, and where did I put it?"
You've saved many of those messages because you need to attend to things they discuss. Some might need your attention today, some next week, and others just need your attention…sometime.
How do you keep track of all this—and how do you call attention to the messages you want to see today? Introducing: Flags.
