(SQL Server) Create HTML Email Reply

The goal of this example is to create a new HTML body where the new reply HTML is at the top, and the original HTML body is below.

The .eml files for this example are available at HTML Reply Email Samples (.eml)

Note: This is only one of a million ways to do it..
