As SC is using Swift and you can send multipart email with Swift it is not supported by SC. So you cannot embed images within a html email and need to reference by url. This is especially complicated if your image is in the database. So please change the email macro so you can add embedded images.
Agree with Albert. Please add more functionality to the email macro.
Hello,
I will discuss your suggestion with our team.
