Re-check your IP after delisting
Free, no sign-up — results in seconds.
1. Confirm the listing
Run the IP through the Blacklist Checker and note which lists show it as listed. Visit each list's own lookup page — it usually explains the reason and links to the removal process.
2. Find the cause
- A compromised email account sending spam — check outgoing mail logs and queue sizes, and reset passwords.
- An infected website — outdated CMS plugins are often abused to send mail through PHP. Scan and update.
- An open relay or open proxy — the server accepts and forwards mail for anyone.
- Bad list practices — sending to purchased or very old lists hits spam traps.
- A shared or neighbouring IP — on shared hosting or with range-based lists, another customer may be responsible. Contact your host.
- Missing reverse DNS — some lists flag IPs with no PTR record or a generic one.
3. Fix it before requesting removal
If the cause is still active, you'll be listed again — and repeat listings are often harder to remove. Lock down accounts, clean infected sites, close relays and pause problem campaigns first.
4. Request delisting
How removal works varies by list:
- Spamhaus — use the official lookup at check.spamhaus.org, which explains the listing and offers removal where appropriate.
- Barracuda — has a removal request form on its website.
- SpamCop — listings expire automatically once reports stop.
- UCEPROTECT — level 1 listings expire automatically after a period without new spam; levels 2 and 3 are range-based and clear when the range improves.
- Most other lists have a self-service removal page.
5. Verify and monitor
Re-check with the Blacklist Checker after the removal is processed (DNS caching may delay the change briefly). Then reduce the chance of a repeat: enforce strong passwords and two-factor authentication, keep websites updated, set outgoing rate limits, publish SPF, DKIM and DMARC, and monitor your IP regularly.
Frequently asked questions
How long does blacklist removal take?
From minutes to days depending on the list. Some expire automatically once spam stops; others process requests manually.
I fixed the problem but I'm still listed — why?
Some lists only expire listings after a quiet period, and DNS caching can briefly delay the change. Re-check after a day.
Should I just change my IP address?
Only if you can't fix the cause. Moving without fixing the problem gets the new IP listed too.
