Domain Reputation Checker

Instantly Spot Risky Domains Before They Impact Your Business.

Fraudo.io makes it easy to check if a domain is trustworthy or a potential threat. Whether it's linked to phishing, fake account signups, malware distribution, or chargebacks, our real-time domain reputation check gives you the insight you need to make fast, informed decisions.

We scan domains for suspicious behavior and track their patterns across global fraud networks. If a domain has a history of shady activity, you’ll know about it before it enters your system.

Smarter Risk Scoring, Backed by Real Data

Instead of relying on static blacklists, Fraudo.io analyzes how domains behave in the real world. We score them based on actual activity like sending spam, triggering chargebacks, or being used for fake signups. Even disposable email services and parked domains are flagged, so nothing slips through the cracks.

Our platform gives each domain a risk score, helping you identify abuse before it becomes a bigger issue.

One API, Total Coverage

Need to check a domain, IP address, or email on the fly? Our flexible API lets you do it all in one call. It fits right into your signup forms, checkout flows, CRMs, or fraud review processes. From phishing detection to identifying temporary email services, it gives you real-time data to filter out fraud automatically.

You’ll stop bots, detect fake users, and reduce spam without slowing down your workflow.

Global Honeypot Network: Always Learning, Always Updating

Our threat network is powered by thousands of honeypots across the globe. These traps capture real-time abuse signals from malware, phishing attempts, botnets, and spam campaigns. That intel feeds directly into our risk engine, so every lookup reflects what’s happening right now, not what happened last month.

The result? You get faster, more accurate data that adapts to new threats the moment they appear.

Understand More Than Just a Domain Name

When someone signs up or sends an email from a new domain, you need to know what’s behind it. Fraudo.io gives you deep insight into each domain’s reputation including when it first appeared, how it’s been used, and whether inbox providers trust it.

We even help you evaluate deliverability. If a domain is likely to land your messages in the spam folder, we’ll let you know.

Want to Check a Domain’s Risk Level?

Just enter the domain name in our checker, and we’ll show you everything we know, risk score, related abuse, spam activity, fraud signals, and whether the domain is disposable or tied to suspicious behavior. You can also analyze the domain’s IP address to uncover additional warning signs.

It’s fast, reliable, and designed for anyone from security pros to startup teams.

Why This Matters

Every risky domain you allow into your platform is a potential threat. Letting just one fake account slip through can lead to fraud, chargebacks, or even damage your email deliverability. That’s why reputation checks are more than just useful, they’re essential.

By screening domains in real-time, you can stop trouble before it starts.

Clean Up Your Email Domain Reputation

Poor email deliverability? It could be your domain’s reputation holding you back. To fix it, you’ll need to:

  • Set up SPF, DKIM, and DMARC correctly
  • Avoid purchased lists and inactive subscribers

Keep your sender IP clean and validate your email list regularly. These steps not only improve inbox placement but also protect your brand’s credibility.

Fast, Flexible API Integration

Fraudo.io’s API is built for speed. Whether you’re using Python, Node.js, PHP, or any other backend, it connects easily and responds in milliseconds. Plug it into your signup forms, user verification flows, payment systems, or backend logic without slowing down your platform.
