Important
Flag a conversation that matters with a star, and everyone who can see it sees the flag. Important has a view of its own, and you can filter and automate by it.

What it does
Flag what matters
One key
Press S, click the star in the conversation’s top bar, or use the right-click menu.
Everyone sees it
Everyone who can see the conversation sees the flag, not only you.
A view of its own
Important lists what is flagged, in All mail and in each mailbox.
Rules can flag it
An automation can mark mail important, for example when a customer has waited too long.
