Use Hangouts right in Gmail
Hangouts work right inside Gmail, where Chat did before. Send photos or emoji, see when people are engaged in the Hangout and message friends anytime, even if they're not connected right now. You can even start or join video calls with up to 10 friends at once. Upgrade Chat to Hangouts by clicking on your photo icon in Gmail's chat list.Learn more
