Why is the sub account not receiving notification emails about submissions?

We have a main account and a sub account that an intern uses.  We have not been receiving emails on that email despite it being added to the account and having full access to the forms.

Adding a Subuser will only allow you to offer these 2 privileges:

1. Edit forms

2. View submissions

Your Subuser won't receive email notifications unless you add him/her as a recipient. Basically, you can add anyone as another recipient if needed.

Just head over to your FORM BUILDER > click SETTINGS at the top > EMAILS on the left > RECIPIENTS tab > then add his/her email to the RECIPIENT EMAILS section and SAVE.
