What this is
A step-by-step guide to removing your domain or IP from a blacklist.
Step-by-step
Identify the blacklist (e.g. Spamhaus)
Determine how serious the listing is
Identify the root cause (spam complaints, bad lists, volume spikes)
Fix the underlying issue before doing anything else
Submit a delisting request
Resume sending slowly and carefully
Important
If you request removal without fixing the root cause, you will likely be listed again quickly.
