If you edit one of your email templates, you can list all of the Runtime Fields from one of the text components. I have manually selected and listed them all below to make this a little easier to track.
The fields are pretty self-explanatory, but you can see the full title if you edit an Email Template, select a ‘text’ component and use the drop-down menu for ‘Runtime Fields’ (Figure 1 below).
