How to Send a Secure Email?

Did you know that a whopping 91% of cyberattacks start with a sneaky email that tricks people? You can avoid being part of this statistic by sending secure emails.

Sending secure emails is like putting a strong lock on your messages. Secure emails ensure that your confidential information remains confidential. And what’s more, sending secure emails also protects the people you’re emailing so their info doesn’t get into the wrong hands.

What is Encrypted Email?

Encrypted email is like sending a secret message in a virtual lockbox. Writing an encrypted email scrambles your words into a code only the intended recipient can unlock.

It’s like conversing in a secret language only you and your friend understand. Imagine sending a super-important email to a friend, like your top-secret cookie recipe.

With encryption, it’s as if your recipe gets magically transformed into a jumble of letters and numbers, making it impossible for anyone snooping around to know your secret ingredient. Armed with the right key, only your friend can decode your email and enjoy your delicious cookies. Encrypted email is all about keeping your private stuff private.

Types of Email Encryption

When it comes to email encryption, there are several options you can turn to. The three main types of email encryption include; 

• Pretty Good Privacy (PGP). PGP uses a public key for encrypting messages and a private one for decrypting them. It is more of a secret code for scrambling emails to ensure that only intended recipients can decipher them.
• Secure Multipurpose Internet Mail Extension (S/MIME). Secure Multipurpose Internet Mail Extension (S/MIME): This method also uses encryption keys. The only difference is that it relies on digital certificates like SSL certificates. Its full name is Secure Multipurpose Internet Mail Extension.
  It is an email signing certificate or personal authentication certificate. S/MIME certificate ensures the sender’s identity and prevents third parties from reading your message. This type of certificate works on public encryption and uses asymmetric cryptography. S/MIME is a type of SSL certificate that is specially designed to secure email communication.
• Transport Layer Security (TLS). This is like a secure tunnel that protects your email in transit. TLS or SSL certificates ensure a secure connection between the sender and receiver of email servers, keeping prying eyes at bay.

How to Encrypt Emails

If you believe you are not a techie, encrypting emails might seem technical and overwhelming. But it’s actually a breeze. Here are three easy ways to send encrypted emails across different platforms:

To remove access before the expiration date:

1. Open Gmail and go to the “Sent” folder.
