Secure messages with a digital signature (using S/MIME) in Salesforce Marketing Cloud
In Salesforce Marketing Cloud, you can attach a digital signature to your outbound email messages to provide a layer of security for your subscribers. The digital signature, which includes a secure certificate and a public key, confirms for your recipients that the message to which it is attached originated from you (i.e., not from an impostor "spoofing" the message). It also serves as a digital seal that assures recipients that the content of your message was not altered in transit.
