How secure are your Email,plz check out?
This should come as no surprise anymore, but your email isn't private. In fact, it's one of the least secure methods of communication you can use. In contrast, phone calls typically aren't recorded and stored, and even if they were, your employer and law enforcement would have to go to court to gain access to them.
Emails are stored at multiple locations: on the sender's computer, your Internet Service Provider's (ISP) server, and on the receiver's computer. Deleting an email from your inbox doesn't mean there aren't multiple other copies still out there. Emails are also vastly easier for employers and law enforcement to access than phone records. Finally, due to their digital nature, they can be stored for very long periods of time, so think twice before writing something down in an email you don't want others to see.
