Unable to receive email notifications from Seller Center.
For the New Seller Center, there will not be any option for you to control your notification settings.
We would suggest you to check your main email inbox/spam folder to search for the notifications.
However, if there is still no notifications being sent to your email, do get in touch with our Partner Support Team through this form.
They will then proceed with necessary action from their end and keep you update regarding your issue.
