Send form content to data from hidden field

Hi 

Is it possible to send a copy of the submission to an email address stored within a pre-populated hidden field?

Thanks,
Matt

Yes, it is possible. Add an Email field, enter the email address as a Default Value in field settings, hide the field and set that Email field as the Recipient Email of the Autoresponder Email.

Or you can just use the Email Notification and set the email address to which you want to send the submission to as the Recipient Email.

Notification can also be sent to multiple recipients.
