If you have team members managing specific creators, you'll need to turn on their email notifications for their creators.
To do this, go to the sidebar menu and click on Settings. Under Business Settings, select Team.
To view all your managers, choose the Admin tab at the top of the page. Select the team member you want to turn on emails and notifications for.
Under Assign Accounts, select the creators your team member manages. Under each creator selection, you'll also have the option to click on Receive Emails to turn on emails and notifications for the creator.
