Thank you for posting your inquiry.
There is no such option available to embed or generate font resource when converting to HTML files.
Aspose.Email API reads the email file and converts it to HTML without having any such option of inserting HTML anchors. You can find all the HTML options for conversion as in our documentation article.
The API automatically adds the separation horizontal lines to the output HTML. Please see the attached HTML file here as output of your MSG file.
Please let us know if we can be of any additional help to you in this regard.
