Adding another email to auto notifications. Do I need to republish the form on my website?

I have about 20 forms on my site for signing up for classes.  I need to add another email to all of these classes to ensure it gets an email each time somebody signs up for a class.  After I add the email on the jotform side do I need to go back and republish each form on my website to ensure the new email will not get the notifications?

Hello! The short answer to your question is, no you don't have to.

Any changes you do on your form won't require you to republish it. You just need to reload/refresh the page where the form was embedded for the changes to take effect.

The only time you would need to is if and only if you're using the Full Source Code of the form as your embed method.
