We use priority scores to help push work through our stream. Right now I've got it set to send an email when the issue is updated, setting the priority score to greater than 50. However, it is sending an email every time the issue is updated once the score is set. So if the score was set yesterday and I update the issue today, it will send another email today. I just want the email once, when the score initially reaches a value greater than 50.
