Verify a user’s email address by sending a validation link. When they click the link in the email, they are returned to the form and the submission is verified.
In WordPress, this gives you a simple way to confirm submissions before changing what happens next. You can then use conditional logic to change the appearance or behavior of the form.
This method can also be used as a form of double opt-in. WS Form also includes an Email Validation demo template to help you build this kind of form.
