I saw no error reports on my page. Not sure what happened.
Check your spam/junk mail folder. I always check my shop (at least) once a day just in case there's a message etc.
Everyone should check their shop at least once a day. Etsy is notoriously unreliable when it comes to sending emails.
@danamarieart: A quick search would show lots and lots of threads in this forum about issues with app and eMail notifications. Assuming that the eMail was sent, too many bad things can happen between Etsy's mail server and your eMail client. The consensus is that a seller needs to check their shop for messages and orders at least daily via a browser until these issues are resolved.
