I recommend posting an idea for a "Send Operational Email" permission. It might just be because it's the end of the day, but I can't think of a way to restrict a user from sending one unless you get Workspaces, build your operational emails in a specific workspace, and then deny the user access to that workspace - which wouldn't be very practical for most users.
Thank you Grant and Josh. That is what I thought, but I just wanted to get confirmation from some experts. I will definately take the recommendation to post it as an Idea.
