(SQL Server) Create Complex Email

This is an example showing how to create an email that has file attachments, contains both plain-text and HTML alternative bodies, and has embedded images within the HTML. The email is saved to a .eml file, which is a text file and can be viewed in any text editor. EML is nothing more than the MIME source of an email. In this example, you'll see that the MIME is structured in three layers of multipart content types. The outermost layer is multipart/mixed. This is typically where you'll find file attachments and attached messages. Underneath the multipart/mixed is a multipart/related envelope. Within this you'll find the "related" items -- which are the items belonging to the HTML body (images and style sheets). Underneath the multipart/related you'll find the multipart/alternative, and this contains the text/plain and text/html alternative bodies.
