How do I change my email address or get another one as backup for contact?

Hi I currently have my work email but would like to add my private email as well, how do I do that? 

Are you looking to change your form email notification or your account email? You can enter more than one for both either way as a back up.

For your Email Notification, please see this guide 25-Setting-Up-Email-Notifications and https://www.jotform.com/help/39-Send-Notifications-to-Multiple-Recipients. As for your Account Email you will have to change that in your My Account page under your Profile Tab which is the first tab.
