Project Description: This is email template utility project. In my scenario, I have lots of different type of email is going outside. However all email has same template.
To separate the template part, I have created Email-Master than rest of the email have only content part.

Before coming to this solution, I have used html email template & xslt.

Some more details is available in my blog.
