E-mail notification suddenly failing

A notification e-mail that has been working properly for quite some time is now failing each time.

Please see attached image from the e-mail history. 

Please advise as to why this e-mail is failing and let me know what can be done to make it succeed

Thanks!

The recipient email was in bounce list: https://www.jotform.com/help/262-How-to-Remove-Your-Email-Address-from-Bounce-List 

It has now been white-listed, so this should solve the problem. In addition to this, you may whitelist our domain names, if the issue continues, as we use Amazon SES method for "noreply@jotform.com" sender.

Here are our domain names:

- us-sub1.jotservers.com

- us-sub2.jotservers.com

- aws-sub1.jotservers.com

- aws-sub2.jotservers.com

- us-app2.jotservers.com

- jotservers.com

- jotmails.com

- jotform.com

- amazonses.com

- email.amazonses.com

- *.smtp-out.amazonses.com

- jotform.co

- secure.jotform.co

- s3.amazonaws.com  

- static-interlogyllc.netdna-ssl.com

Let us know if you need more help, we will be glad to assist you.

Thank you!
