Email Validation & Fraud Check
Verify every email address the moment it's captured. Our multi-layer engine confirms an inbox is real and deliverable, then scores fraud risk in real time — so you protect your sender reputation, block fake signups, and keep clean, trustworthy data flowing into your systems.
What is Email Validation & Fraud Check?
Email validation is a sequence of checks that confirms an address is genuine and able to receive mail. We start with syntax and RFC compliance, then verify the domain exists and resolve its MX records. A live SMTP handshake confirms the mailbox itself is deliverable, while catch-all detection flags domains that accept any address indiscriminately. Layered on top, we identify disposable and temporary addresses and role-based accounts such as info@ or admin@ that rarely belong to a real prospect.
Beyond deliverability, every address is given a fraud risk score that combines signals like domain age, exposure in known data breaches, and behavioural patterns. The result is a single, GDPR-aligned decision you can act on at the point of capture — accept, review, or block — without storing more personal data than you need.
Best for:
- Cleaning signup and marketing lists to protect sender reputation
- Blocking fake and disposable signups at the point of registration
- Reducing payment fraud and downstream chargebacks
- Improving deliverability and lowering hard-bounce rates
- Pre-screening inbound leads before they reach your sales team
- Account-takeover prevention and login risk assessment
Why teams choose Email Validation & Fraud Check.
Lower Bounce Rates
Catch undeliverable addresses before you send. Removing hard bounces keeps your delivery metrics healthy and your mail out of spam folders.
Stop Fake Signups
Disposable and throwaway addresses are flagged instantly, so bots and bad actors never make it past your registration form.
Reduce Fraud Loss
A composite risk score built from domain age, breach exposure and behaviour helps you decline high-risk transactions before they cost you.
Protect Sender Reputation
Mailbox providers reward senders with clean lists. Validating up front preserves your domain reputation and long-term inbox placement.
Every email passes a multi-layer check
+ continuous updates to disposable-domain and breach datasets
Specialist Tip
On a typical marketing list, more than 20% of addresses are invalid, risky, or already decayed by the time you send. Validating at the point of capture protects deliverability far more effectively than periodic batch cleans — you never let a bad address into the list in the first place, and you stop the slow erosion of your sender reputation before it starts.
