Best tool to send notification to referrer in Opportunity Marketplace

Summary:

We would like to send a notification to employees who have referred candidates to a posting. The goal is to contextualize it with content about our referral program for the specific posting (not all postings are bonus eligible - so if bonus eligible include those details, if not bonus eligible content with that info included with the thank you).

What is the best tool for this? It looks like the referral related notifications in the recruiting content library are for the the candidate.
