November 13, 2024 – Retarus has enhanced its Transactional Email Service by adding a unique, innovative function for added security. Message Signing now makes it possible for transactional emails sent directly from business applications to be signed by way of S/MIME certificates. This enables companies to better protect their brands and customers, while more effectively preventing sophisticated cyberattacks, such as spoofing or phishing. In addition, this feature guarantees that the contents of the email have not been altered since it was sent and that the message actually originates from the stated sender. Message Signing is available with immediate effect.
