We have many quick solutions in the system. We need to be able to NOT email the user on some of them, on a case by case basis depending on the issue/solution. We also need to do this for calls. we don't always want the user to get 2 emails (one on call logging, and one on closure). Sometimes we just need to log/close calls without them getting emails. For example. We fix something over the phone, we don't always want them to get 2 emails about that phone call.
Could you include a field on your call screen that allows you to opt in/out of emails in these cases and include these in your IPK Workflow notify rules?
You could then set that field value on the quick solution settings and it would then not meet the IPK Workflow rule and not send an email
