Comodo's Free Email certificates take seconds to install and allow you to use the digitally sign and encrypt features built in your email client to secure and authenticate your emails.

An SSL email certificate ensures your mail cannot be read by anyone but the intended recipients. They also ensure your message was not modified during transmission and allow recipients to confirm your identity as the sender of the message.

Email certificates can be applied for and collected using Internet Explorer, Firefox, Opera, Safari and Flock browsers. For best results, however, we recommend using Internet Explorer.

Why do I need a Secure Email Certificate?

  • Authentication - Email passes through many different computer systems without your knowledge. Not only are you unaware of the mail flowing through these public systems, you may also not know where these computers are located, or even who owns and maintains them. A secure email certificate lets you add a digital ID to your email to prove that the message and attachments originally came from you.
  • Privacy - Any non-encrypted email you send can be very easily intercepted and read. Someone may be able to snoop on your email inbox, or grab the messages as you wirelessly check your mail on a laptop. Comodo's email certificates protect your mail from prying eyes by providing end-to-end encryption between you and your contact. You encrypt the message on your computer and it can only be decrypted by the intended recipient when it arrives at their computer. Nobody can read it en-route.
  • Integrity - Regular, unsecured email can easily be intercepted and modified. Messages can be changed so that information is removed or even added without your consent. Adding a digital signature to an email with a Digital Certificate means that it is impossible for anyone to alter the contents of your mail without your recipient being alerted.
