Does anyone use Mailto scripts in any of the Reply Templates?

I would like to use something similar to the below, so that the person receiving the email has two options and just selects option and sends reply without having to type anything.  However whatever way I've done this it is not displaying correctly (as a hyperlink named Type 1) in the email and when you click the link it is dropping the description and not pulling through the RequestID from Manage Engine.

<a href="mailto:test@test.co.uk?subject=$RequestID%20-%20Type%201&amp;body=I%20would%20like%20to%20select%20Type%201%20under%20reference%$RequestID">Type 1</a>

Has anyone any ideas where I am going wrong?

Many thanks,

Lisa
