Email Verification Trusted by Thousands of Companies

This level of email address validation goes well beyond basic checks by ensuring that the email's inbox is 100% functional and able to accept incoming mail.

Instantly query our API to determine a user's Email Address Reputation in real-time and filter out low quality & abusive users before they can negatively impact your site.

Detect Temporary & Disposable Email Addresses

Fraudsters commonly use free disposable email services (temporary email addresses) to gain something of value such as account access, downloads, eBooks, 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 or trial offers. If your site is suffering from abusive behavior then blocking disposable emails is a crucial step to eliminate fraud.

Our 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. IPQ's 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, email lists, and other data!

Abusive Email Address Detection

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. This data is used to identify valid email addresses that have recently engaged in fraud, such as using a stolen credit card or creating a fake account. All IPQS clients can take advantage of this feature which significantly reduces the chance abusive users can access your site or negatively impact your business.

What Makes Our Email Verification Service Different?

Email Verification is not an exact science and it is quite challenging for any email validation service to maintain a high standard of quality. This is due to many mail servers on the web using SPAM filters and similar types of firewalls that outright block the verification of certain emails. For example, and do not allow direct email verification. IPQS has developed proprietary methods to support these providers and many others that block verification, but many services that provide email validation cannot determine if these emails are valid. IPQS can support nearly any email address provider and our team has 24/7 monitoring in place to detect any anomalies with the quality of our results. The extensive measures we take to ensure quality are easily noticed when comparing our service to any other provider in the industry.

Detect High Risk Email Addresses

Additionally, 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. IPQ's 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. Another unique feature of all checks performed by our email address verification system is to test if the email has recently been reported as a honeypot or spamtrap. 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 15 Data Points Per Lookup

Email address lookups through our service also include forensic details such as extracting the first name from an email address, detecting if the email belongs to a popular email service like, and checking for role-based or generic accounts such as "sales@". This additional information is helpful for customizing the email validation service to meet your exact needs. For example, it would be easy to determine if an email address was from a personal account like or if the email belongs to a business or company.
