cid means you have an inline attachment so the attachment source is a part of the message's MIMEContent and a browser won't render that by default. You could use something line MIMEKit to convert the raw Mime Message into something that the browser can render eg https://stackoverflow.com/questions/31417916/mimekit-mimemessage-to-browser-renderable-html.
