Ever ignore emails and then completely forget to reply to important ones? One of the newest features in Gmail is its new Nudges feature. It’s an automated feature that will surface emails to the top of your inbox the service thinks require your attention and reply. It’ll include a highlighted message telling you how long ago you received the message. If you’re using the new Gmail, you get this AI feature enabled by default. You can, of course, turn this off in the settings if you don’t want it.
