Our IP address subnet has been blacklisted by Verizon and I've been attempting to get it delisted, but the whitelist page consistently bringing me to an error page upon clicking submit
Here is the message we are receiving when attempting to send to any Verizon email address:
571 Email from xxx.xx.xxx.xx is currently blocked by Verizon Online's anti-spam system. The email sender or Email Service Provider may visit http://www.verizon.net/whitelist and request removal of the block.
Please advise on what we can do to correct this promptly; else, we will need to start advising our clients of Verizon's inability to maintain a functional mail platform and set of procedures and advise that they take their business away from Verizon. Thanks in advance.
