Any idea why my recipients aren't receiving notifications?

Both of my forms are functioning properly, but they're not being received via notification email. Any idea why?

I have checked the email address that you're using on your forms and I can see two of them are currently in our bounce list, here are the emails with their reason: 

rstrayer@s****o-2.com - Reason(s) : smtp; 552 5Ycm1t01t2Hqjy901Ycnm4 Message fails DMARC

scott.batiste@p******s.com - Reason(s) : smtp; 450 4.7.1 : Recipient

I have removed them from our bounce list and you should receive emails now, I will also suggest you to follow this guide in order to avoid bouncing: How-to-Prevent-Email-Bouncing-Related-Issues

If you notice that emails are not being sent, please follow this guide in order to remove your email address from our bounce list: How-to-Remove-Your-Email-Address-from-Bounce-List

Also, ask your email provider to white-list our IP addresses, here you will find our info to white-list: Whitelisting-JotMails-IP-Addresses

Thank you!
