Changes look good and address stakeholders' comments. I tweaked the landing page wording from 'free-text templates' to 'free-text messages'. Swapped the subsections of some of the pages in 'Using NHS Notify'.

I've already reviewed this, we just needed Jake to submit a new PR because I made minor additional edits as part of my approval. Hopefully this will merge the changes.
