Hi @Gavin,
Welcome back to the community! 
Do you have the latest version of HivePress installed, (and any extensions that you’re using)?
There was actually an update a while back that improved the available dynamic placeholders/tokens. When you visit the template for the corresponding email, you should find a fairly large list of these below the box where you compose the email.
Additionally, you may find this topic I created a while ago useful.
I hope this helps!
Edit: I believe the two dynamic tokens you’re looking for are:
- %listing.title%
- %listing_url%
You can also combine the URL token with HTML to make it clickable, like so:
<a href="%listing_url%">View Your Listing</a>
Cheers,
Chris
