Created an automation in JSM when an issue is created from the open portal, check if the email is in the 'Customers' list. If not, add the email to the customers list.
When a new valid email is entered, the automation throws an error that the email is invalid. Yet, a confirmation email for the created issues was received from JSM at the same email address.
Any thoughts as to how to capture new customer emails automatically when they create an issue. Having to invite and approve each customer isnt going to work at scale.
