como puedo ver los datos de un formulario no enviado?

Me gustaria hacer un formulario con varias paginas pero que si finalmente el cliente no finaliza el mismo y no envia el formulario poder ver sus datos de contacto para tratar de recuperar la venta.

¿es posible hacerlo con un formulario? (que guarde todos los datos aunque no sean enviados.

¿se podría hacer con dos formularios? 

If I understand your question correctly, you want your form input data to be saved so that user can comeback and submit form later. Is that correct?

Yes it is possible to achieve your requirement and here are the options available:

#1. Save input data in session: User can save the input data in session that is stored in our server. Please be noted that this feature requires two forms and the main form should have the "Page Break" field. The data is saved only on the click of the next button.

#2. Auto Fill feature:  You can enable the "Auto Fill" feature of your form which will save the input data every few seconds. Please be noted that auto fill feature saves the input data in browser cookie. That means if the user access the form again from other browser, other system or clear the browser cache, the saved data will not be accessible.
