How to have email field validated?

Also; is there a way to set up field validations, in particular, email validation to ensure that bogus emails are not being provided by the person filling out the form?

You can use our Email Validator widget: https://widgets.jotform.com/widget/e-mail_validator. Users will have to validate their email in order to submit the form.

Hope it helps.

Let us know if you have any further questions.

Thank you!
