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 or trial offers. 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!

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.

What Makes Our Email Verification Service Different?

Email Address Verification is not an exact science and it is quite challenging for any Email Address 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 support nearly any mail service provider and 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.

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.

Detect Spamtraps, Honeypots, and Frequent Complainers

IPQS Email Reputation Scoring also includes detection for emails reported as a honeypot or spamtrap. 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.

Precision accurate email validation by IPQS detects invalid, disposable, and abusive addresses including spamtraps and honeypots.
