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!

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. This is due to the popularity of SPAM filters and similar types of firewalls that outright block the email verification process for certain mail service providers. IPQS has developed proprietary methods to support these providers and many other services that block traditional email verification attempts. This feature is one of the many ways IPQS detection rates stand apart from competitor services, as many other verification providers are unable to offer the same quality & verification coverage.

IPQS can improve email deliverability across any mail service provider. Our team has 24/7 monitoring in place to detect any anomalies with data quality. 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

Take email validation to the next level with email fraud scoring. Track abusive emails 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 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 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 email or suppress your lists for all emails detected 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 15 Data Points Per Lookup

Email address lookups through our service also include forensic details such as extracting the first 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 is helpful to customize the email validation process to meet 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.
