Why I'm not receiving pending payment notifications?

The second problem is that we are not getting email notification of pending payments. 

I have just checked the recipients of your form and I can see emails are sending without any problem, I would recommend you to please check your spam/junk folder, if you find the emails there, then marking them as not spam should help you to receive future emails in your inbox folder. 

Here is also a guide that will help you to know why emails are not sending: https://www.jotform.com/help/364-Why-I-am-not-Receiving-Email-Notifications 

Also, if you keep experiencing problems with your emails, please try setting up a custom sender using the SMTP method, this way you will use your own mail server info so emails should not be blocked: https://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form 

I hope this helps.
