Free scan accuracy note: This tool queries RBL providers through public DNS resolvers (Google, Cloudflare, Quad9). Some blacklist providers — including Spamhaus, SpamRATS, and others — restrict or block queries from public resolvers, which may result in missed listings or false negatives. For maximum accuracy with direct server-side DNS resolution, join the waitlist for our premium scan engine.
Demo mode: Use the buttons above to see real scan results instantly. Clean Domain shows a healthy reputation, Listed Domain shows a compromised sender, or try Bulk Demo to compare multiple domains side by side.

The Real Cost

What happens when you get blacklisted.

It's not just spam folders. A single blacklisting triggers a chain reaction that compounds across every email you send.

✉️

You send an email

Invoice, proposal, or campaign goes out from your domain

🔍

Receiving server checks RBLs

Gmail, M365, Yahoo query Spamhaus, Barracuda & 80+ lists

Reputation spirals down

Bounce rate climbs, engagement drops, other ESPs start filtering too

One listing. Thousands in lost revenue.

Most businesses discover they're blacklisted only after the damage is done — when clients complain they never got the invoice, when campaign open rates crater overnight, or when their sales team's cold sequences go completely silent.

The average blacklisting goes undetected for 72 hours. That's three days of email silently disappearing into the void while your team has no idea.

Core Capabilities

More than a blacklist checker.

Real-time scanning, intelligent scoring, and actionable remediation — not just a pass/fail list.

90+ RBL Scanning

We don't check 10 blacklists and call it a day. Blacklist Intelligence scans across 90+ providers including Spamhaus, Barracuda, SORBS, SpamCop, and dozens of regional RBLs.

Health Score & Grading

Every scan returns a weighted health score from 0–100 with an A-F letter grade. Not all blacklists hit equally — we weight by severity and impact on actual deliverability.

A-F GradingWeightedSeverity Tiers

Bulk Domain Scanning

Agencies managing 50+ domains can't scan one at a time. Paste a list, get results for all of them. Compare health scores across your entire portfolio.

Multi-DomainCSV ExportComparison

Continuous Monitoring

Set it and forget it. Scheduled scans run every 4 hours and alert you the moment a new listing appears — before your deliverability tanks.

Guided Delisting

Getting listed is one thing. Getting delisted is where most people get stuck. We provide pre-filled delisting forms, direct links, and step-by-step remediation instructions.

How It Works

From scan to fix in under 60 seconds.

No account needed. No install. Just type a domain and go.

1

90+ RBLs Queried in Parallel

We fire real-time DNS queries against every major blacklist provider simultaneously — Spamhaus, Barracuda, SpamCop, SORBS, and 86 more. Results stream in live.

Get a Weighted Health Score

Not all blacklists hit equally. We weight by severity and real-world delivery impact. Spamhaus listing? Critical. WPBL? Low risk. Your score reflects what actually matters.

Fix It with Guided Delisting

Each listing includes severity, direct removal links, and pre-filled delisting forms. No googling around for obscure removal pages. Click, submit, done.

Free scanning is just the beginning.

Scheduled monitoring every 4 hours, bulk domain management, and API access are on the roadmap.

Built For

Who uses Blacklist Intelligence?

Email Marketers

Check your sending domains before every campaign. One blacklisting can tank your entire send — catch it before your open rates crater.

"We ran a 50K campaign and 38% bounced." Turns out their shared IP got listed on Spamhaus three days prior. A 30-second scan would have caught it.

Agencies & Consultants

Manage client domains in bulk. Generate white-label reports that justify your retainer and prove the value of proactive monitoring.

"We scan all 40 client domains every Monday morning." Two listings caught last month before any client noticed. That's the kind of value that prevents churn.

MSPs & IT Teams

Monitor infrastructure IPs and mail servers across your client base. Get alerted before tickets start flowing in about bounced emails.

"A client's mail server IP ended up on SORBS." Their Exchange server was relaying through a compromised IP. Caught it in bulk scan before the helpdesk tickets started.

Sales Teams

Cold outreach lives and dies on deliverability. Check your sending domains daily to make sure your sequences actually reach the inbox.

"Reply rates dropped from 8% to under 1%." Their outreach domain was on Barracuda and SpamCop. Two weeks of prospecting effort — completely wasted.

A complete picture of your sending reputation — in seconds.

Most blacklist checkers show you 10 providers and call it done. We scan 90+ because the blacklist that blocks your email might be one nobody else checks.

Weighted severity scoring

Spamhaus listings tank your deliverability. WPBL listings barely register. Our scoring reflects real-world impact — not just listing count.

Domain + IP resolution

Enter a domain and we automatically resolve it to all associated IPs, then check every one. Enter IPs directly for infrastructure-level scans.

Instant delisting links

Every listing includes a direct link to the blacklist's removal page. No hunting through documentation. Click, submit, move on.

FAQ

Common questions.

A Real-time Blackhole List (RBL) is a database of IP addresses and domains identified as sources of spam or malicious activity. Major email providers check these lists before accepting your email. If your domain or sending IP appears on one, your messages can be rejected outright or routed straight to spam.
The free tool checks 90+ RBL providers including all the major ones — Spamhaus, Barracuda, SpamCop, SORBS, and dozens of regional blacklists. The upcoming premium version will add scheduled monitoring, historical trending, and advanced filtering by severity tier. Join the waitlist to be notified when premium features launch.
First, don't panic — not all blacklists carry the same weight. Our health score factors in severity. For critical listings (Spamhaus, Barracuda), use our guided delisting workflows that include direct links to removal forms and step-by-step instructions. Most delistings resolve within 24–48 hours.
Automated monitoring is coming as part of the premium tier. Once launched, you'll get scheduled scans running every 4–12 hours with instant email alerts the moment a new listing is detected — giving you hours of lead time to respond before deliverability drops. Join the waitlist to get early access when it launches.
Both. Enter a domain and we resolve it to its associated IP addresses and check everything. Enter an IP directly for infrastructure-level checks. Bulk mode supports mixed lists of domains and IPs.
Yes — API access is on the premium roadmap. The REST API will return JSON with health scores, individual RBL results, and recommendations. Perfect for integrating blacklist monitoring into your existing dashboards or automation workflows. Join the waitlist to get early API access when we launch.
