Google recently unveiled a new Gmail feature – emailing Google+ users whose email address you actually don’t know. Moving forward, Gmail will suggest Google+ connections as recipients when a user composes a new email, without revealing the recipient’s email addresses to the sender until the recipient either replies to the email or follows the sender. While some Gmail users may welcome the feature, others may see it as a privacy threat… and of course Google has enabled it by default. Thankfully, there’s a way to prevent random Google+ strangers, companies or services that may abuse this feature from emailing you using solely your social network profile. In order to turn off the feature, you’ll have to follow a few simple instructions posted by Google on its help pages.
