Tracking links in Emails: Do not track hint

[heebinho]

@escopecz pointed me to this hidden gem. I think this could be a worthy inclusion.

I think the changes I just committed should fix the Vale warnings. There were a couple of things - inline code blocks need a double backtick to encase them and I think you had too many spaces in the code block indentation - I just used VSCode and hit return on the end of the code block annotation to find out what it was expecting. Also changed 'disabled' to 'turn off' as we're trying to move towards more inclusive language.

Thanks for the PR @heebinho 🚀
