No email you send is secure and especially when it comes to Google’s Gmail. This is because they’re using keywords from your emails to target advertising.
While it’s true that Google employees aren’t reading your email, the potential of skirting the rules (much like the NSA in recent times) always remains.
If you’ve thought of not using Gmail, there’s no point because all email is not secure. The protection that it offers users (SSL, in Gmail’s case) only protects your information during the first leg of its journey as it passes through a number of servers and reaches the intended recipient.
However, there does exist a standard which offer protection from end-to-end namely OpenPGP which needs universal acceptance from email service providers and clients too. Of course, this isn’t going to happen since it isn’t the best interests of Google, the US government or even Microsoft.
So, what do you do?
It’s simple, really. Keep sensitive information out of emails as much as you possibly can. However, as a second resort, you can use encryption if you want to prevent the cops, corporations or the crooks to not read your emails.
But there’s a problem with that: not only will the recipient require your password but also compatible software yet most of all, they might not be as tech-savvy as you are.
That said, there’s another solution that you can try and which involves the use of Sendinc where both recipient will need free accounts that are offered by this service. Also, you need to have strong passwords but don’t need to know each other’s passwords.
