You may have noticed that emails are sent daily to non-registered users once the Remind Users to Create/Update Q&A Profiles Enforcement Rule conditions are met (default: after one day):

To prevent the constant emails sent to non-registered users, you may want limit to the notifications to be sent at specific timeframes only or stop completely after a number of days.
Add a no notification condition specifying the when you want the notifications to stop. I.e. email registration reminders stop being sent a week after the original invite was sent:

You could specify additional conditions, reminding the non-registered user sporadically without the necessity of spamming their inbox (continuous daily emails). I.e. email reminders stop 7 days after the original invite; start again after 30 days and stop after 37 after the original invite:
