[Amazon Simple Email Service (SES)](https://aws.amazon.com/ses/) now supports Secure/Multipurpose Internet Mail Extensions (S/MIME) signing, giving you a way to help recipients verify your emails are authentic. An S/MIME signature lets recipients confirm that a message was sent by the holder of the From address and that its content was not altered in transit.

Previously, senders who needed S/MIME had to sign each message themselves before submitting it to SES, adding complexity to their sending. With this feature, you store your signing certificate in [AWS Certificate Manager](https://aws.amazon.com/certificate-manager/) and enable S/MIME signing for your sender identity. SES then signs your messages automatically as you send, so you don't have to sign messages yourself beforehand. Recipients whose email clients don't support S/MIME can still read the message normally. This gives security-conscious senders a simple way to add digital signatures to their email while continuing to use their existing SES setup.

This feature is available in all AWS Regions where Amazon SES is available. To learn more about S/MIME signing in Amazon SES, visit the [Amazon SES console](https://console.aws.amazon.com/ses) or refer to the [documentation](https://docs.aws.amazon.com/ses/latest/dg/send-email-authentication-smime.html).
