An update to Google+ now allows users to send and receive emails from other Google+ connections even if they have never exchanged email addresses.

The setting lets users specify whether they would like to receive mails from people in their circles, extended circles or anyone on Google+. They can also choose not to participate in the feature.

Any message that appears in the recipient's Gmail inbox will say that it was received "via your Google+ profile", according to Google's blog post.



Users will be able to write as they would in other professional email settings and include the info in their Google profile.



If a user receives a Google+ message form someone outside his circles, the message will automatically appear in Gmail's "social" folder, not the "primary" folder.
