Can you have a different email for each form?

Yes, this is possible.

Here you can find a guide to see how to do this: http://www.jotform.com/help/25-Setting-Up-Email-Notifications and also you can check this guide: http://www.jotform.com/help/39-Send-Notifications-to-Multiple-Recipients in case you want to send the same notifier to multiple email addresses.

If you have any questions, please let us know.
Thank you.
