Google has recently created an option for Gmail users to ensure that their email is properly encrypted using SSL. All you have to do to finally encrypt your email is go to the Gmail Settings page, and next to "Browser connection" select "Always use https." When viewing Gmail, check the address bar. If she says "https://mail.google.com," you know that your email is encrypted SSL. If she says "http://mail.google.com," so your email is transmitted in plain text, which makes it very easy for hackers to access your session information and read your email.
Since most people have sensitive personal information stored somewhere in their email archives, the smart thing to do is make sure your email is encrypted. If you send sensitive information over an unencrypted connection, you put yourself at risk of identity theft.
