Help with why we are not getting email notifications Wooten Appliance

We have been using Jot Form for some time and as of around 4pm yesterday we are no longer getting email notifications when a form is sent from a customer. Please advise.

I checked our email logs for the address in your form and it looks like the emails are being sent successfully from our end.  Check your spam/junkmail folders to see if they are being filtered there. 

If they are not, let us know and we will be happy to have another look.
