Two forms are not sending email for submissions

I have two customers and both of them are not receiving form submissions.

This customer's has been intermittent but as of today they have not received 1 email. I have access to their email box and confirm it is not going in junk/spam etc. Strange, is that if I add my john@904.technology address to the form recipient it sends just fine. This customer is on Godaddy.com's email platform.

This customer's was working perfectly yesterday and is now not receiving any email submissions to their inbox. So basically the same as above, the emails are correctly stored in jotform but not sending to their email address, which is with Comcast.net

Are yall being blacklisted by these two service providers? 

Please help as this is urgent and I am afraid it might be affecting more of my customers

The email address of the recipient has been placed on our bounce list. But I think you've figured this out already. Please advise your client to add noreply@jotform.com to their safe sender list. Here's a guide for additional information related to the bounce email problem:

The recipient is using Comcast address. The emails are sent based on our logs so I suspect Comcast blocked the emails from reaching the recipient's inbox. Still, advise your client to add noprely@jotform.com to their safe sender list. If they have an option to whitelist a domain, please ask them to do so for jotform.com.

Or, centralize your forms to use an SMTP: https://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form. Basically, sending form emails using your own email address to your clients. So, this way, they'll only whitelist your email address instead of Jotform.
