Hi TomBk,
Thanks for posting your question here. I reviewed the automatic Notification options that are available for individual threads on our forum and the only one I would expect to send you a daily notification regardless of whether there have been replies is the one called “Daily Email Digest”.
If you were to choose the “Immediate Notification by Email” notification option instead, I would only expect you to receive an email notification any time a new message is posted to the thread in question.
If you would like to check which type of notification you subscribed to and/or cancel the notification, you should be able to do so by opening the appropriate thread, clicking the “Notify” tab along the top of the forum page and proceeding as desired.
