Craft CMS HTML Email Template I have a contact form that works using Postmark and Contact Form plugin.

I'm trying to find a way to edit the format of the email that I'm getting when someone sends a message via the website contact form. 
E.g.

Subject: 
Message from: {{ name.field }}

Full name:
{{ name.field }}

Email:
{{ email.field }}

Department:
{{ department.field }}

Message:
{{ message.field }}


I can see that there's a "HTML Email Template" option in Settings > Email. But I couldn't find any documentation.
The "HTML Email Template" option in Settings > Email in the Craft control panel is completely unrelated to the Contact Form plugin.

If you want to change the body of the email that gets sent out, you'll need to write a plugin that listens to the beforeMessageCompile event as documented here: https://github.com/pixelandtonic/ContactForm#the-contactformbeforemessagecompile-event
