Hi,
Could you first take a look at the logs in Admin > Private Area > Logs.
You’ll see the notifications logs there, so you can make sure that WP Customer Area attempted to send an e-mail.
If you see an entry but didn’t receive anything, it should be a server sending issue, or a problem with the receiving email account. There are tons of reasons that could prevent an e-mail to reach its destination, but best way would be to first take a look at the logs from WPCA.
Regards.
