Google published a new post on the Official Gmail Blog regarding a new Gmail update where random people on Google+ will be able to send emails to you Gmail account without you ever having given them your email address.
These messages from strangers will arrive in your Gmail inbox just like emails, but the stranger won’t know your email address unless you respond. “Your email address isn’t visible to a Google+ connection unless you send that person an email, and likewise, that person’s email address isn’t visible to you unless they send you an email,” Google explains.

This feature is rolling out over the next couple of days to everyone that uses Gmail and Google+. You’ll get an email with information and a link to the setting when the feature is available.
