I receiced a submission form my noreply@jotform.com, but the sender did not leave his email. Is there any way to retreive his email, so i can respond?

You will need to have an email field in your form that will allow the user to type in their email address.

Unfortunately if the sender did not type the email address there is no way to know the origin.

You can set the email field to required so that this information has to be supplied.
