At least, that will soon be the case if youre both a Gmail and Google+ user and have the right settings enabled. A new Gmail setting lets you choose whether you want people to be able to send an email to your Google+ profile — even if they dont have your email address in their contacts. The four options let you control whether any Google+ user, or just people in your circles or extended circles can email you. You can also disable the feature by selecting no one. Even if you do let people send you emails through their Google+ connection, your actual email address wont be revealed unless you respond to the email.
