Spamhaus is the blocklist most mail servers check first. A listing means your mail is bouncing or landing in spam across a large share of the internet, right now. The good news: removal is always free, and many listings clear on their own once the problem stops.
Free, no signup. See if Spamhaus, Barracuda, SpamCop, or other major blacklists have you listed.
Examples: 203.0.113.42 or example.com
| Blacklist | Status | Response |
|---|
| List | What It Means | What to Do |
|---|---|---|
| SBL | Your IP was tied to spam activity. | Your ISP or hosting provider handles removal. |
| XBL / CSS | A hacked machine, compromised account, or bad mail setup is sending spam. | Fix it, then remove the listing yourself. |
| PBL | Not a spam listing. Your IP is in a range that shouldn't send mail directly, like home broadband. | Running a real mail server? Request an exclusion. |
| DBL | Your domain showed up in spam, phishing, or malware. | Fix the cause, then request removal. |
Requesting removal before you fix the problem just gets you listed again. The usual suspects: a hacked email account, malware on a machine on your network, a website form sending spam, or a mailing list full of old or purchased addresses. Our delisting checklist walks through each one.
Look up your IP or domain at check.spamhaus.org and follow the steps for your list. Removal is always free; Spamhaus says anyone charging for it is running a scam.
A Spamhaus listing can hit any sending IP on any day. Generator Labs checks your IPs and domains against Spamhaus and hundreds of other blacklists and alerts you by email, Slack, SMS, or webhook when a listing appears, so you're fixing it before your customers notice. Free for your first host.
It depends on the list. Some listings expire a few days after the spam stops; others clear as soon as you request removal through check.spamhaus.org.
No. Spamhaus never charges for removal.
Only if you send mail straight from that IP. Mail sent through your provider's mail server isn't affected.
