Yep, you need to validate an email address on your form. Here’s the easy way to do it.

Now add a reference to it in the header of your page:
Now, tell your Entry that it should use the EmailValidatorBehavour from the FormsToolKit
Now, add a label and tell it’s IsVisible to be triggered when the EmailValidator fires:
Now the Label will appear when the EmailValidator’s IsValid field is False
