Hey! I had the same issue last month. To spamhaus zen unblock ip, you’ll need to submit a delisting request on their site. Make sure your IP is clean first—check for malware and spam activity.
For prevention, I’d recommend using a tool like MXToolbox to monitor your IP’s reputation. Also, set up SPF and DKIM records if you haven’t already. It’s a bit of work, but worth it to avoid this headache again.
