To keep your email secure and private and to keep it away from the access of any snooper you need to encrypt it in three ways; the connection from your email service provider, your current actual email messages; and the stored, cached or archived email messages. If you don’t encrypt the connection of your email provider and keep checking and sending the messages the other users on your network can steal your email login credentials and any messages you send or receive especially when you frequently use public Wi-Fi while sitting in a shopping mall or a restaurant there is great risk that hackers, spammers or other snoopers might attack and steal your sensitive information so encryption saves you from such serious security threats. Your email messages are in great threat while they travel over the internet which might be intercepted by any cyber criminal like hacker or spammer and your sensitive information can be in wrong hands so encrypting the email conversations before sending them to the receivers make them unreadable even if intercepted or stolen. The saved messages or cached mail messages stored in your device memory must also be encrypted so that others uses your computer or mobile can’t get the access to your sensitive information which can be a major threat to you.

Let’s start learning how to do do it all and secure all your email conversations.

How to Encrypt Email Connections?

When you access sensitive information pages like your bank account or online payment page you use a Secure Socket Layer (SSL) and Transport Layer Security (TLS) encryption, similarly when you need encrypt email and protect the connection between your email provider and your computer or another device, you must ensure that the SSL/TLS encryption is active. If it is so, the website address (URL) will begin with HTTPs instead of HTTP; depending on your browser, some other indications of a secure and encrypted connection are, a notification next to the address bar or a small yellow padlock icon on the status bar below the browser window. If you can’t see this you can do it by following these steps;

  • Type an alphabet character “s” at the end of the ‘HTTP’ and tap Enter
  • If your email provider supports SSL/TLS, that instruction will usually redirect it to encrypted server.
  • Then browse your account settings to see whether you can activate encryption by default for future logins.
  • If you can’t force the encryption, check with your provider as they may not support SSL/TLS.

How to Encrypt Email Messages?

If you want the email messages you send or receive to be protected or encrypted you must do some task before the time and not only you but the recipient to whom you send messages must also perform some steps ahead of time.

In a pinch, you can use a Web-based encrypted email service like ‘”JumbleMe” or the other ”Sendinc”, but doing so will force you to trust a third-party company.
