To learn more about sub-account users, please do check this guide that we have: http://www.jotform.com/help/232-How-to-Share-Forms-with-a-Sub-Account-User.
Regarding your question, I'm not sure if I fully understood it. When you add sub-account users, you are just adding a group of accounts that you would like to share your forms. Those accounts will have the freedom to create, edit, view their own forms and they can purchase their own subscription plan. I've checked the list of email addresses that you have and our servers sent them a message about a form that was shared by you and a link to create a JotForm account, but I do see that there are emails not sent to: email@example.com and firstname.lastname@example.org, these email addresses might be incorrect, the rest showed that our servers successfully sent them a notification.
If you are looking on how to add your users to the email notifications of you forms, you can do that by following this guide: http://www.jotform.com/help/39-Send-Notifications-to-Multiple-Recipients
If I misunderstood your question please do provide us more details of it to better assist you.
