What I'd suggest doing is putting a 'section' heading using Word's 'Heading 1' Style at the top of your ‘Legal templates’ 'section', ‘Recruitment templates’ 'section', etc. Then adding a heading for each of your email 'templates' using Word's 'Heading 2' Style.

You can then simply add an automatic Table of Contents to the start of the document and have all those headings appear there. Plus, if you tell Word to hyperlink the Table of Contents to the entries, simply clicking (or Ctrl-clicking) on any of Table of Contents entry will take you to the relevant 'template' page. If you want to be able to go back & forth with the hyperlinks, you'll also want to add the corresponding buttons to Word's Quick Access Toolbar (QAT).
