How To Check If An Email Address is Valid?
Using the verification tool above, you can check if an email address is valid and determine if the email is an active inbox, that's ready to accept mail. This indicates that the email account is active and a real user is behind the email address. Taking these measures ensures you can send your client or prospect a successful message in the future. One of the most frustrating parts of running a business is having a good lead, but not being able to get in touch with them. In other situations, fake accounts may be causing problems which are likely using invalid email addresses.

Validate Email Addresses with 99.9% Accuracy
There's many choices for service providers when it comes to email address validation, but results vary greatly. When verifying an email address, being off by just a few percentage can greatly impact your inboxing score and cause your company's 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.
Imagine having a prospect attempt to sign up for your site or services, but they are rejected due to their mail server not allowing most email validation services from verifying it exists. This is a scenario we see almost every day from new clients that have experienced poor quality among other services and one of the many ways our service excels compared to the competition. IPQS ensures you'll never face a similar issue, with email scoring that's 99.9% accurate.
Why is Email Verification Important?
Due to fears of SPAM and data leaks, many users online are reluctant to give out a real email address and frequently use fake emails or temporary inboxes 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.
Protect your company from malicious users with email fraud prevention by IPQS. 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 an 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.
Beyond user quality, email verification is an important practice 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. The IPQS email verifier removes spamtraps and invalid emails from your contact lists. Only messaging valid emails that are active with the mail service provider will ensure you can maintain a healthy sender score and avoid blacklists. It's best to validate marketing lists every 6 months at a minimum.
Detecting Fraudulent Email Addresses
Detect fraudulent emails with deep insight and big data directly from the IPQS threat network. Take advantage of email address fraud prevention powered by machine learning and AI that analyzes hundreds of millions of email addresses per day across every region. Generate accurate email address reputation scores based on recent abusive behavior, fraud reports, and signals from the user's activity, which measures behavior across the web's most popular sites. Email address fraud scores are generated in real-time to identify risky accounts or payments.
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. The results in the email address lookup above will determine if the email address has been leaked in a recent data breach. This data is also available via an email validation API lookup.
