We are referring to these different links. The Name of the link is important to remember as you will need that for the email template.
For this example, I am using the "Nanny" One from the screenshot

Next, I will go to the job email template, and copy this tag and paste it in to the email

In the tag that says {name} this is where you will put the name of the link. Replace the name of your link where it says name
Above in my example I named it Nanny
Here is how my tag will appear.
[[candidate_permanent_shareable_link-{Nanny}]]
You will want to make sure it is the exact same spelling.
