Sorry but this is not currently supported in Form Wizard. An email entered by the user is just a text question like any other, Form Wizard doesn't know it is an email address so it has no ability to treat that data with any special handling. Form Wizard Pro is not designed for extensibility with custom code, it does what it does and that is all. Maybe in the future I will add something where a text question can be flagged as an email question and then it might be possible to use it in scenarios such as this. I'll add it in my project tracker as a wish list item.
Best,
Joe
