Email Address Verification
Verify email addresses in real time with accurate, actionable risk intelligence.
IPQS Email Verification helps businesses validate email addresses and identify risky or fraudulent emails in real time. Verify individual addresses through our Email Verification API or process bulk email lists to quickly identify invalid, disposable, suspicious, and high-risk addresses.
Go beyond basic email validation with detailed reputation and risk scoring. Improve email deliverability, reduce fraud, and make better decisions with actionable intelligence on every email address.
More Than Valid or Invalid: Email Risk Intelligence
Basic email validation can determine whether an address is properly formatted, but a valid address is not necessarily a trustworthy one. IPQS analyzes multiple technical, reputation, and risk signals to provide a more complete assessment of each email address.
Identify Risk Beyond Basic Validation
IPQS evaluates characteristics that can help distinguish legitimate email addresses from invalid, disposable, suspicious, and potentially fraudulent addresses.
- Syntax and format validation
- DNS and MX record checks
- Mail server availability
- Disposable email detection
- Email reputation analysis
- Fraud and abuse indicators
- Real-time email risk scoring
These signals give businesses additional context when evaluating email addresses during registration, account creation, lead capture, checkout, and fraud prevention workflows.
Improve Email Deliverability and List Quality
Invalid, disposable, and high-risk email addresses can reduce the quality of your customer and marketing data and contribute to higher bounce rates. IPQS helps businesses identify problematic addresses before they enter their databases, CRM systems, or email marketing platforms.
Use the Email Verification API to validate addresses in real time, or use bulk email verification to evaluate existing lists before sending campaigns. Identify problematic addresses earlier and maintain cleaner, higher-quality email data across your business.
How Email Verification Works
IPQS evaluates email addresses using multiple technical and reputation signals to determine whether an address is valid, deliverable, and associated with potential risk. The result provides actionable information that businesses can use to make decisions in real time.
1. Submit an Email Address
Send an email address to the IPQS Email Verification API for real-time analysis, or upload an existing list for bulk verification.
2. Validate the Email Address
IPQS checks the address for proper syntax and analyzes its domain, DNS records, MX records, and mail server information to determine whether the address appears technically valid and capable of receiving email.
3. Analyze Reputation and Risk
Additional signals help identify disposable email addresses, suspicious domains, and other characteristics associated with fraud, abuse, or low-quality email addresses.
4. Receive a Verification Result
IPQS returns the verification result and available risk signals through the API. Businesses can use this information to accept, reject, flag, or route an email address for additional review based on their own requirements.
Email Verification API

Email Verification Explained
Detect Temporary & Disposable Email Addresses
Fraudsters commonly use free disposable email services (temporary email addresses) to gain something of value such as account access, free trials, downloads, and other premium features, content, & services. These emails provide zero value in return since disposable email addresses are often deleted and never used again. Disposable emails are also frequently used to create duplicate accounts, engage in credit card fraud, and take advantage of free services. If your site is suffering from abusive behavior then blocking disposable emails is a crucial step to eliminate fraud.
IPQS email address verification API service provides confirmation that the email address does not belong to a temporarily or disposable email service in addition to being a valid email. IPQS disposable email blacklists are updated in real-time to provide the most effective service in the industry for stopping temporary email addresses. Ensure your users are signing up with valid emails and instantly increase the value & ROI of your user base, potential leads, email lists, and other data!
The Most Accurate Email Verification Service
Verify Email Addresses with the Highest Degree of Accuracy and Precision
Abusive Email Address Detection
IPQS places an emphasis on email address fraud prevention at the core of our email validation service. Even when an email address is valid, there is still a chance the user has intent to engage in abusive behavior. Luckily, IPQS scores hundreds of millions of user events per day across popular sites. This data is used to identify valid email addresses that have recently engaged in fraud, such as using a stolen credit cards or creating fake accounts. All IPQS clients can take advantage of this feature which significantly reduces the chance for abusive users to access your site & negatively impact your business.
What Makes Our Email Verification Service Different?
Email address verification is not an exact science and it is quite challenging for any email validation service to maintain a high standard of quality in determining if an email address exists. This is due to the popularity of SPAM filters and similar types of email server firewalls that outright block the email verification process for certain mail service providers, making it harder to determine if an email address is valid.
IPQS has developed proprietary methods to support all major mail service providers and many other services that block traditional email verification attempts, which includes analyzing the SMTP server corresponding to the MX records and special relationships with major mail service networks. These unique features are some of the many ways IPQS can verify email addresses with better accuracy than similar email validator services. Our email checker techniques have been fine-tuned over 10+ years of enhancing sender reputation for 3500+ clients.
IPQS can improve email deliverability across any mail service provider while minimizing the bounce rate. Our team has 24/7 monitoring in place to detect any anomalies with data quality or connecting to a SMTP server. High bounce rates especially hard bounces or bad email data can be a nightmare for any email marketing team, so IPQS places an emphasis on providing the best email verifier data in the industry. This is achieved through proprietary techniques gained from over 10 years of email checker technology that IPQS uses when verifying MX records and connecting to an STMP server to check emails.
Detect High Risk Email Addresses
Take email validation to the next level with email fraud scoring. Track abusive emails, compromised mail servers, and stolen identities online with real-time blacklists that quickly detect new threats. Most disposable email address detection providers use stale blacklists that are not able to keep up with the newest disposable email services and the domains they add weekly to bypass filters. IPQS blacklists are updated in real-time to ensure that the newest disposable email services are immediately blacklisted to prevent duplicate & fake accounts, user generated SPAM, abusive users, as well as other fraudulent activity associated with temporary emails.
Lookup Email Creation Date Age
Lookup the email age date for any email address to determine an estimate of when the account was first created. Detecting email age is an important data point from our email verifier software which can enhance email reputation and improve hit rates for fake or risky users with suspicious emails. Since fraudsters typically cycle through new domains very quickly, the API also includes the email's domain age, making it easy to detect new domains created specifically for hosting abusive email addresses. This value is listed on all email validation API responses as the "First Seen" date.
Bulk Email Validation
Cleanse your bulk email lists from bounces to improve your sender reputation score and avoid email deliverability issues. Using our bulk email verification service, your marketing lists can be uploaded and immediately processed. Easily download all clean emails or suppress your email list for accounts with poor reputation scores. Bulk email validation is great for verifying your existing lists and older user data. We recommend using our email validation API to screen all new email addresses before they are added to your lists.
Detect Spamtraps, Honeypots, and Frequent Complainers
IPQS email reputation scoring also includes detection for emails reported as a honeypot or spam trap. These email addresses are incredibly stealthy and directly impact your sender score and inboxing rates. Detection for frequent complainers also makes it easy to avoid email addresses that are likely to unsubscribe or report your message as SPAM. We recommend avoiding these emails when performing mass mailing and newsletter marketing as they may cause your IP address or domain to be blacklisted by certain mail providers and ISPs.
Over 25 Data Points Per Lookup
Email address lookups through our email verifier service also include forensic details such as analyzing the mail server, extracting the owner's name, detecting if the email belongs to a popular mail service like gmail.com, and checking for role-based accounts such as "sales@", "hello@", "support@", etc. This additional information from our email validator along 20+ other data points are available to customize the email validation process for your exact requirements. For example, it would be easy to determine if an email address was from a personal account like gmail.com, hotmail.com, etc. or if the email belongs to a business or company.
Precision accurate email validation by IPQS detects invalid, disposable, and abusive addresses including spamtraps and honeypots.
