Hi Ali,
Hope you are well!
Unfortunately, the functionality to send an alert when an invitee registers for a specific session in the event is not available. While we do offer planner alerts within the event, this specific option is not included in the feature set at this time.
I understand your perspective and apologize for any inconvenience. But, it sounds like a great feedback. I suggest you to post this as an Idea/feedback for our product team by going to Cvent Community > Participate > Product Ideas.
We encourage you to always submit your ideas or any challenges you face while working with the product. As it also help our Product Development team to review the possibilities and if it works we may try to incorporate such changes in our future releases.
Please let us know if you have any further questions.
