A large part of your online life revolves around your email address. It acts as a central hub for almost everything you do: Travel documents and itineraries arrive there, it’s home to receipts for all your Amazon purchases, it acts as a recovery mechanism for the sites and apps you sign up for and then forget your login details. And, of course, there are all the emails you send.
Your inbox holds plenty of private information—and in many cases secrets—that when pieced together can build up a profile of your interests, movements, and social connections. But email privacy can often be neglected. The threats faced depend on who you are. For businesses, phishing attacks launched through emails can lead to entire corporate networks being compromised. But for individuals there are privacy concerns beyond working out if your account has been hacked.
