Overview

[REF] Further extract the portion of sendTemplate that relates to rendering

Before

Rendering functionality in the main code block

After

Functionality in it's own function, required inputs (at this stage) are clear.

Technical Details

This is primary for the purposes of simplification at this stage so the function is protected. It might make sense to make it public in the near future and directly add test cover

Thanks @eileenmcnaughton makes it much clearer. I think we should keep it protected for now because I think we might want to change the inputs and/or name once we work out what we're doing with enhancements to token processing / rendering.
