How do I receive the submitted data?

Salve!!!

scusate ma non riesco proprio a capire come fare a utilizzare il form che ho creato, una volta spedito ad un cliente il form affinché lo compili come fa a salvare le modifiche e a spedirmi copia modificata?

When your form is submitted an email will be sent to you and you will be able to see the submission in the submissions page, to see your submissions follow this guide: http://www.jotform.com/help/269-How-to-view-Submissions. 

When you create a form it has by default an email notifier, if it does not, please follow this guide to add one: http://www.jotform.com/help/25-Setting-Up-Email-Notifications. 

Hope this will help you.
