The evolution of email began as a test by Ray Tomlinson in 1971 who successfully sent the first network email in history. It has since grown to be a common necessity with over half of the global population owning 3.9 billion active email accounts. Throughout this time, email has made promising advancements from the preliminary stages of AOL, Delphi, Hotmail, and Outlook 97 to the more mature stages of Gmail, Outlook, and Yahoo Mail. 

I’m not here to judge—but if you’re still in the dated email pool of AOL or Hotmail, then I strongly advise you to upgrade to a more modern service. I say this because let’s be real, can you actually trust someone with a email? (And yes, this was a real email—my email back in the early 2000s.) 

It’s common to believe that a strong email password is going to keep your messages private and protected. But in reality, email is a common target for cyber breaches from hackers, identity thieves, and phishing scams. So, how do we protect ourselves from these crimes?

Answer: Sign up with a service that offers email encryption.

Why You Should Encrypt Your Emails

Encryption is an integral part of sending and receiving confidential emails. And since email is constantly used as a means to communicate, email encryption stands as a necessary practice worth implementing. 

I understand it can be easy to settle for Gmail as your prime email service, but by no means should you label them as a secure provider. In fact, Gmail allows third-party services to secretly peep through your emails to serve targeted ads. Not only that, but it uses its own ecosystem of services to collect copious amounts of data on you. Along with large tech corporations, hackers can intercept and read your private messages. If you’re sending confidential information like passwords or your address through a non-encrypted email, then you’re holding yourself vulnerable to a dangerous cyber attack.

How Email Encryption Works

Securing a message with email encryption essentially disguises the content within your message. This protects confidential information from being intercepted by unintended recipients. An encrypted email is often protected through authentication with public and private keys. When sending an email with sensitive details, you use your desired recipient’s public key to encrypt the message. They then use your private key to decrypt the message and reveal the email’s contents.

Now, I’m not saying all of this to scare you and hype up the need to buy expensive software for proper email encryption and security. Instead, I’m here to raise awareness about cyber threats and equip you with the tools and knowledge necessary for prioritizing your right to privacy.
