It’s easy to think of email as something that just works. You open up Outlook or log into Gmail and your mail is there. Most people aren’t even aware of the vast, complex set of systems required for email to even work—and we don’t blame you. It’s extremely complicated.
That being said, if nobody is actively managing your email, providing protection for the underlying technology, and making sure that it was and remains configured properly, it’s possible that your email could be working fine while opening you up for unseen threats.
