Notifier email no longer working

Hello, I was getting notifier emails that the Reference form I created had been submitted; however, that is no longer the case.  I have checked it and can't figure out what has changed.  I have checked my junk folder and they are not there.  Any thoughts?  This is the form.  Thanks so much!

I have checked the email history log and see that the notification emails are being sent from our end without any issue.

I see that you are using a custom sender email address for this notification. Could you try changing the sender email address to JotForm default email address and see if that works? 

If you want to use your own email address as the sender email address, you may consider using SMTP email address for the notification.
