If you’re using the redesigned Gmail on the web, here’s one handy trick that hasn’t really been talked about. Android Police reports you can quickly add someone as a recipient in an email by just using the @ + name option. Just type that into the body of the email and you’ll get a list of suggested contacts to be added to the recipient list. Once you select the name, it gets highlighted and linked (as mailto:) in the body of the email and it shows up as a recipient, too. Again, this only works for the redesigned Gmail on the web for now.
