A recent update to Google email service Gmail will make it easier for any Google+ user to send someone a message.

Google saysthe tweak will allow any user of their social network to send an email, but they can only see your address if you respond back.

For example, when composing an email, suggestions might pop that include Gmail contacts and people in your Google+ circle, but only their names.

The change has sparked concerns that any one will be able to send someone with a Gmail account unwanted messages. However, there is an easy way to fix this. In Gmail settings, users can scroll down to "Email Via Google+" option and select who can send messages this way, from anyone to no one.
