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
Your IP is on a blacklist
550 5.7.1 rejected — message blocked before it reaches inbox
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.
Don't wait for the bounce notices.
Premium monitoring catches listings in hours, not days. Get notified when it launches.
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.
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.
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.
Historical Trending
Track your reputation over weeks and months. Spot drift before it becomes a crisis. See exactly when listings appeared and resolved across your entire domain portfolio.
Same sender. Two very different outcomes.
This is what your recipients experience depending on your blacklist status.
❌ Blacklisted Sender
Your invoices land in spam. Proposals never arrive. Clients think you've gone silent — and start calling competitors instead. You lose deals you never even knew were on the table.
✅ Monitored & Clean
Every email lands exactly where it should. Invoices get paid on time. Proposals get read. Your reputation stays pristine because you caught listings before they ever became problems.
Automated scanning. Instant alerts. White-label reports.
Everything agencies and MSPs need to manage client reputations at scale — coming soon.
From scan to fix in under 60 seconds.
No account needed. No install. Just type a domain and go.
Enter Any Domain or IP
Type a single domain, paste an IP, or drop in a list of up to 100. We handle domains, IPs, and mixed lists — no formatting needed.
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.
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.
Agencies & Consultants
Manage client domains in bulk. Generate white-label reports that justify your retainer and prove the value of proactive monitoring.
MSPs & IT Teams
Monitor infrastructure IPs and mail servers across your client base. Get alerted before tickets start flowing in about bounced emails.
Sales Teams
Cold outreach lives and dies on deliverability. Check your sending domains daily to make sure your sequences actually reach the inbox.
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.
