There is absolutely zero I can do about it. Our server is on zero blacklists.... Below is checked against the top 80 blacklists....

We have all the security required set up perfectly. Here is a sample email sent to me from the server. We send with TLS encryption, Spam score = 0, spam flag = no, virus scanned = OK, SPF passed, DKIM passed, (cost me $300 for software to do this), DMARC = pass, Suspicious flag = NO

I sent an email to their abuse email with all the info they requested 4 days ago with no response. It's out of my hands now.
