Email Verification That Actually Works

Stop bad signups. Catch fake accounts. Protect your business.

Fraudo.io’s email address verification gives you the power to spot bad emails before they ever hit your system. Whether you’re dealing with disposable accounts, typos, or high-risk users, we help you verify, validate, and protect in real time.

Plug into our API or drop a CSV – either way, you’ll clean up your lists fast and filter out risky or worthless emails. Every check taps into thousands of data signals from live user behavior across the web. You’ll know instantly whether an email is real, safe, and worth your time.

Email Verification Built to Fight Fraud

Real users. Real results. Less junk.

Fraudo.io’s email verification is built to stop fraud early and clean your data at the source. It blocks disposable and temporary email addresses, catches spam traps, and filters out typo-ridden or fake domains.  

The system can spot role-based emails like "support@" or "sales@" and flag invalid addresses before they ever reach your lists. Using smart SMTP checks, Fraudo.io also verifies whether an inbox is live and ready to receive mail. Every email is scored in real time for fraud risk, helping you reduce bounce rates and dramatically improve inbox placement. The result? Fewer fake users, cleaner data, and better engagement from the people who actually matter.

Keep Your Lists Clean & Your Sender Score Strong

Bounces, blocks, and spam complaints destroy your email reputation. Fraudo.io helps you avoid all three by verifying addresses before they become a problem.

Whether you're sending one-to-one messages or running high-volume campaigns, cleaning your email list improves deliverability, protects your domain, and saves your brand from blacklists.

Clean emails help you reach more people and bring in more revenue.

Bad email data is expensive. Fix it before it costs you.

More Than Just Syntax Checks

Go Beyond Syntax. Get the Full Picture

Fraudo.io does more than just check if an email looks valid. We dig deeper with multi-layered intelligence. First, we verify if the inbox actually exists and can receive messages. Then, we analyze the email’s reputation, looking for a history of spam, abuse, or fraudulent activity. You’ll also see how old the domain is and whether it’s tied to trustworthy or suspicious behavior. We monitor real-time activity to spot emails involved in fake signups, scams, or spammy behavior. And with automatic blacklist monitoring, we flag risky sources before they reach your system.

Email Fraud Scoring

Stop fraud at the gate.

Every email that passes through Fraudo.io gets a real-time fraud score. That means you’ll know right away whether you’re dealing with a safe user or someone trying to trick the system. We flag emails linked to fake account creation, stolen credit card activity, phishing attempts, or abuse across other platforms. Since we monitor millions of events daily, you don’t have to guess who to trust. Just use the score to block the bad ones before they register, buy, or cause trouble.

Disposable Email Detection

Temporary emails are often used to get past free trials, grab downloads, or abuse signup bonuses. They're trash, and they mess up your user data. Fraudo.io detects these throwaway accounts in real time and keeps them out of your system.

Our live-updated database of disposable providers catches new domains within minutes of being created, not weeks later like most tools.

Easy to Use. Even Easier to Integrate.

Use our lightweight API for real-time checks at signup or form submit. Or drop a CSV into our dashboard to clean a whole list in minutes. Either way, the setup is quick and painless.

With Fraudo.io’s bulk verifier tool, you can upload your entire list and get fast, accurate results packed with detail. Our system checks each email for deliverability, spam traps, risk level, common typos, domain trust, and even the age of the email address. You’ll gain access to over 25 data points per email, giving you a full picture of list quality so you can make smarter decisions, reduce bounce rates, and protect your sender reputation — all in just a few minutes.
