Why domains typically get listed
SARBL finds domains by scanning spam reports it receives from mail systems.
If a domain shows up mainly in spam, SARBL can list it.
A domain can get flagged through its use in the FROM address.
It can also get flagged through the TO address, a link, or an embedded image.
Spammers often buy cheap domains and burn through many of them fast.
Some domain endings cost as little as five dollars a year.
SARBL tries to catch this pattern by linking domains to shared infrastructure.
That includes shared subdomain IPs, shared name servers, or repeated content patterns.
Legitimate senders get caught when their platform gets abused by a spammer.
A compromised account or an open sign-up form can trigger a listing this way.
How to check if you're listed
You can check a domain directly against public.sarbl.org with a DNS lookup tool.
URIBLs query the domain as-is, unlike IP blacklists that reverse the address.
To check example.com, you would query example.com.public.sarbl.org.
A result of 127.0.0.2 means the domain is listed.
No answer at all means the domain is not listed.
Multi-blacklist lookup tools that include public.sarbl.org can run this check for you automatically.
How to get removed
SARBL does not offer a self-service removal form.
Removal requests go through email, sent straight to SARBL's team.
You can reach them by emailing SARBL's team directly.
Explain clearly why your domain should not be listed.
Include specific examples from the email that triggered the listing.
Name the exact domains used in the FROM address.
Name any domains used in the TO address as well.
List any domains used in links or images inside the email body.
This level of detail matters more than a general appeal.
Vague requests without examples are harder for SARBL to act on.
If you run a marketing or mailing platform, say so clearly.
Explain that the listed domain belongs to a client, not your own spam campaign.

How long removal typically takes
SARBL does not publish a fixed turnaround time for removal requests.
It is a small, email-reviewed service, not an automated system.
Expect a manual review rather than an instant delisting.
Response times will vary based on request volume and the detail you provide.
A clear, detailed email gives you the best chance of a fast review.
FAQ
How do I check if I'm listed on SARBL?
Query your domain directly against public.sarbl.org using a DNS lookup tool. Format the query as yourdomain.com.public.sarbl.org and check the response. A reply of 127.0.0.2 means you are listed. No reply at all means your domain is clean.
Can I remove my IP from SARBL?
SARBL does not list IP addresses, it only lists domain names. If your IP is blocked somewhere, that block is coming from a different list. SARBL's own FAQ confirms it never blacklists based on IP address. Check which domains tied to your sending setup might be the actual issue.
Why is my domain listed if I'm not a spammer?
Spammers sometimes use legitimate marketing or mailing platforms to send messages. If your domain appeared in the FROM, TO, or body of a spam email, it can get listed. This often happens through a compromised account or an abused sign-up form. Contact SARBL's team and explain the situation with specific examples.
Does SARBL charge a fee to delist a domain?
SARBL has not published any delisting fee on its site. Removal is handled through email rather than a paid service portal. If that changes, SARBL's own site would be the place to confirm it.
How does SARBL decide which domains to list?
SARBL reviews spam reports it receives from other mail systems. It looks for domains that repeatedly appear in those reports. It also looks for shared traits across many spammer domains, like shared name servers or subdomain IPs. This helps catch spammers who rotate domains to dodge blacklists.
