They Can See Your Movements
If you’ve used your email to make reservations, buy a plane ticket, or even search for vacation spots, scammers and hackers could know immediately. What’s more, if they can access your calendar or a list of your meetings, they’ll pretty much know where you’ll be and at what time. Sounds scary, but since we use email to do many of these things, it’s not hard for someone to get this information from your account. What’s worse, they can use it against you.
