Hello,

JotForm 'Xverufy' Widget can be used to check if the email entered by users is working or not. You can also use the 'E-mail Validator' Widget that sends a pass-code to email entered by the user which is then used to validate the email address.

We hope you find this helpful. Please do not hesitate to contact us if you have any issue.

Thanks! 

Thank you for your quick response ..

Is there a free one please ??

The E-mail Validator widget is free of charge. 

Here's how it works:
