No Edit, but Edit Triggers

I have started the roll out of my application. Several Forms have script that sends an email to the users when the record is edited. The problem is that the users are poking around the application to get used to its features and whenever they look at a record through the edit button, it generates an email whether or not the data is changed. I know I can compare the old and new values before sending the email, but that it a lot of code. Is there a simpler way to detect whether or not the data actually was edited?
