You Can Now @ People in Gmail
You Can Now @ People in Gmail by howtogeek.com
Apps like Twitter, Slack, and Facebook let you direct messages to a user by typing @ followed by a username. Gmail now does the same thing, sort of.
Compose a new message in the new Gmail and, while writing the text, type “@” followed by the first few letters of a contact’s name. You’ll be recommended a few people, as shown above. Select someone, either by hitting “Enter” or by clicking them.
