There's many choices for email checker service providers when it comes to email address validation, but results vary greatly. When verifying an email address exists, being off by just a few percentage can greatly impact your email deliverability inboxing score and cause your company's email marketing campaigns or messages to end up in the SPAM folder. Similarly, you may end up with false-positives that could prevent legitimate users from signing up or getting in touch with you.

Many email verification services experience reliability issues with verifying catch all addresses. IPQS uses a proprietary algorithm to ensure 99.9% accuracy with verifying deliverable addresses.

Why is Email Verification Important?

Due to fears of SPAM, data leaks, and even email scams, many users online are reluctant to give out a real email address and frequently use fake emails or temporary email addresses from disposable email services. These services also provide an easy solution for fraudsters to create duplicate accounts and bypass registration filters. Using a simple email verifier performs real-time expert email validation to ensure users are entering valid emails with healthy reputation scores. Maintaining low bounce rates by rejecting invalid addresses can significantly improve sender reputation to increase email deliverability rates.

Protect your company from malicious users with email fraud prevention by IPQS paired with the ability to detect disposable email addresses or a fake address. A reverse email lookup can detect accounts with fake emails, disposable inboxes, or even stolen user data using our free email validator service. Validating emails in real-time through our email verification API can greatly decrease fraudulent behavior and improve the value of your user base. It can also be helpful for detecting typos from users with good intentions, such as when a user accidentally misspells their email address.

Email Verification Service Experts

Beyond user quality, trusting a quality email verification service is an important decision to ensure your email can be successfully delivered directly into a user's inbox, rather than landing in the SPAM folder or bouncing back due to being blacklisted for sending to invalid addresses. The IPQS email verifier removes spamtraps and invalid emails from your contact lists to build sender reputation trust. Only messaging valid emails that are active with the mail service provider will ensure you can maintain a healthy sender score and avoid mail server blacklists. It's best to validate marketing lists every 6 months at a minimum due to frequent account changes on email servers.

How To Check if An Email Address is Leaked?

Email reputation scores can quickly change as emails are frequently exposed by data compromises and database leaks. IPQS monitors dark web leaks and compromised data through our Dark Data™ program. The email addresses exposed by these data breaches are commonly used by hackers and malicious users to create fake accounts and purchases, while still using a valid email address.

Our email fraud checker incorporates leaked data signals as well as recent email fraud abuse reports. The results in the email address lookup above will determine if the email address has been leaked in a recent data breach or engaged in recent abuse like scams or fraudulent account activity. This data is also available via an email validation API lookup.

Email Scammer Checker

Email scams have trended upwards over the last few years, with over 1 billion emails sent per day representing scams, SPAM, phishing, malware, business email compromise (BEC), and similar abuse. The IPQS email scam checker can identify high risk emails including normal looking email accounts that have previously facilitated online scams through a major email service provider. Simply enter an email address in our free email checker to test the inbox against our email scammer blacklist.

Our free email scam checker also identifies disposable email addresses which have a very high correlation to facilitating malicious email abuse. Lookup any email address to see if it's been involved in scams, abuse, or is simply an invalid email address.
