We enhanced the Box Sign API with the ability for developers to suppress email notifications sent to signers requesting their signature. This allows organizations to create their own signature request notifications for signers, enabling them with the ability to white label the signing experience for their signers.
Example use cases include the ability to leverage SMS notifications rather than email notifications and the ability for organizations to deliver signature requests notifications to signers using their own white-labeled delivery method.
