Hello Rob,
Thank you for contacting us.
We don't send notification email to reviewer when merchant curate (publish/hide/archive) reviews.
In case merchant "Edit" reviews, an email will send to the reviewer in which she/he can disapprove the change.
Let me know if you have any questions.
Best,
Kien Tran

does a reviewer get notified when their review is published?
