I have checked one of your forms and noticed an email recipient address in our bounce list:
Dfirstname.lastname@example.org is IN the bounce list
Reason(s) : smtp; 554 resimta-po-24v.sys.comcast.net
I've already removed the email address from our bounce list you this address receives emails now, you could also check the other email addresses where you're not receiving emails in our bounce list, this guide will help you with that: How-to-Remove-Your-Email-Address-from-Bounce-List
You could also follow this guide in order to prevent bouncing issues: How-to-Prevent-Email-Bouncing-Related-Issues
Hope this helps.
