How can I retrieve the senders email address?

Hi,

Unfortunately, you did NOT include andy Email field on your jotform http://www.jotform.com/form/11545804278

So, there is no means to capture any email account/address data from the form respondents.

User guide: http://www.jotform.com/help/30-Notification-Autoresponder-Email-Details

You should add an Email field on the form to retrieve senders Emails.

Inform us if you need further assistance.

Thanks.
