What level do I have to upgrade to...

...to be able to have multiple emails cc'd on form completions?

Hello,

You can upgrade to any paid plan to be able to add multiple email recipients to your notification email.

You can check out the paid plans and features here: https://www.jotform.com/pricing

Please note that after upgrade, you can add up to 10 email recipients per notification email. If you need to add more, you will need to create a new notification email.

I hope this helps.
