"Reminder: Your Feedback is Important!"
However, it's really hard to know which of my support tickets I'm rating. Tickets are sometimes closed hours or days after I comment that they're resolved. Other times they're closed without my saying so. I don't want to rate the assistance I received based on the wrong ticket. The Sisense Case number is provided at the end of the email, however, given that it's a time-consuming experience to visit and interact with the Support Portal:

And assuming Support Portal performance is a big challenge, maybe providing the support case title in the survey is more achievable.
