Embed images for email
Create an unsent email message whose local raster images travel with its HTML. The host retains responsibility for recipients, delivery, disposal and application-specific mail policy.
This uses the same bounded local-image authorization as the editor image workflow.
Use it in your application
Set the trusted local base folder and enable the intended local-resource selection policy before loading a document that refers to local files.
Await email export after editing. A pending Source draft is applied before the message is built, and unsupported or unauthorized local image references are reported.
The returned MailMessage is owned by your application. Set its envelope fields and pass it to your chosen delivery service only after your normal send checks. Dispose it after use.
using var message = await editor.Content.GetEmailMessageWithLocalImagesEmbeddedAsync();
message.Subject = "Account update";
// Set recipients and deliver through your application's approved mail workflow.
