    Does JotForm support form validation?

    Asked by Victor on December 30, 2011 at 07:30 PM

    Such as if an email address is valid or checking for required areas that haven't been filled out?

    Hi Victor,

    Yes! it is possible. You can either use Text Box and set its validation to Email, or you can simply use Email Tool under Quick Tools.

    Also, to set field as required, click on the field and then click Required button above it.

    If you are looking for a feature that checks email whether it exist or not then sorry it's not possible with JotForm. 

    Please let us know if you have further questions. Thank you for using JotForm and have a great new year!
