Cancelled workflow reverts back all previous steps in the workflow

Hi Guys,

My client uses Dynamics 365 and they would like to make the lead qualification process a bit conditional, i.e. the lead will be converted to account and opprotunity only if the email the industry field has a value equal "not for profit". If the condition is not satisfied then I want the lead to stay open and I need an email activity be created to notify the manager to approve lead conversion even if certain conditions are not met. 

As always, I would like to do this with no coding (no plugin or custom WF etc). 
I did some research in CRM forums and the option given was to use realtime workflow and stop the workflow with status "Canceled" if the the abovementioned condition is not met. In my realtime WF, I also try to create the email activity before the "stop workflow" step. But, becasue the workflow is stopped with status "Cancelled" (versus "success"), my email activity is not trigerred. :(

Anyone has any idea how to fix this or maybe some other approach to this problem?

Thanks
