For many people, the first sign that their email has been hacked comes when a friend shoots them a text or an email saying, "Hey there. Uh… I think your email was hacked… unless you meant to send me that link to the Viagra store." Or you might figure it out because you can no longer log in to your account, or your smartphone can't retrieve your messages. Or maybe you can log in to your email, but find that your inbox is suddenly empty and all of your contacts have been deleted. No matter what tips you off, when your email is hacked (notice I say when, not if, here), the impact can be disastrous.
