I have a form set up to email users on submission, edit, and deletion. We have 2 administrative fields in the form that are hidden from the user. When the administrative fields are edited, I do not want an email to be sent. 

I can't find a way to say, send email except when field1 and field2 are edited. At first I was going to go through and make a workflow for each field that on update should trigger an email, but then if the user updates multiple fields would they then receive multiple emails?
