Leads with no email addresses - forms

Question

EDIT FOR MORE DETAILS:
- form in question can be accessed when email sub clicks 'communication preferences' in email footer
- once ''communication preferences' clicked, email sub is redirected to LP that includes this form
- only component on form that is email sub facing is the CTA (screenshot 1)

Happy Friday!
 
Anyone have knowledge on how I can possibly have leads with empty email addresses entering Marketo after 'filing' out this form? The form only hosts a CTA.

Reccos on how to prevent this?

In case people land on that page directly (i.e., not from the tracked link in the footer of the email), or to speak broadly, make a form submission w/o their Munchkin session associated with a person record in the Marketo database, then such form submission would result in new people getting created in Marketo with empty email address value. This is expected Marketo form behavior. To remediate this, you can add the email address as a required field on the form, enable form prefill on it so people with the Munchkin associated session don't have to fill the form, and for the rest, the form isn't submittable w/o providing a valid email address.

Are you using this form to accept hidden/background form submissions? If so, then you should ensure that you don't call the submit() function w/o at least adding the Email Address as one of the hidden fields with its apt value set. Making hidden/background form submissions w/o including the Email Address field would create records in your database with an empty email address value. Also, if you embed/use this form anywhere w/o the requisite script to add the email address as a hidden field, people will get created with no email address, as you don't have that field on the form in the first place.

var myForm = MktoForms2.allForms()[0];
myForm.addHiddenFields({
	//These are the values which will be submitted to Marketo
	"Email":"test@example.com",
	"FirstName":"John",
	"LastName":"Doe"
	});
myForm.submit();
