Comodo’s Free Email certificates allow you to use the digitally sign and encrypt features built into your personal email client to authenticate and secure your email communications. This allows recipients of your emails to confirm your identity and ensure that the email you sent was not modified during transmission. It is also simple to fully encrypt your communications to prevent unauthorized viewing.

If you have a Macintosh and you use Apple Mail to check your email, installing a certificate is incredibly simple when using Safari to download the certificate. Just fill out the application for secure email certificate, then click the download link in the confirmation email. Done. Safari downloads the certificate and integrates it seamlessly into your machine’s Keychain, and an email certificate in the Keychain integrates seamlessly to Mail.
