If the recipient's email service provider receives an unencrypted email, chances are it will send it out as a plain text message. This comprises the security of your personal information. Security experts claim emails are the most vulnerable when they get to the recipient.

What happens if email is not encrypted?

Email messages and attachments can also be intercepted as they travel over the email network. By default, emails are not encrypted as they travel from your emails servers to the recipient. This means that if hackers are able to compromise this data, they can read your emails and attachments.

Should I delete unencrypted emails?

It is recommended that you do NOT purge other emails from your account in case you need to recover them later. When an email that contains sensitive information needs to be completely purged from your inbox, simply deleting the email isn't enough.
