IP Quality Score Email Address Verification API

Improve IP Quality Score email address verification deliverability and increase open rates by verifying your contact list. Avoid high bounce rates due to invalid or non-existent addresses by detecting spam traps, honeypots, temporary & disposable email services used by fraudsters, and other bad actors online.

Proper email list hygiene reduces bounce rate, inboxing and spam filter issues, and complications from typos & misspellings. The result is improved engagement, higher conversion rates, and a better sender reputation.

Using the IP Quality Score email verification API, your developers can perform real-time lookups that evaluate an email address and return a number of valuable data points. Specifically, the lookup will check if an email is valid and actually exists with the mail service provider, and if it has been used for good behavior like registrations or payments in the past (as evidenced by the “First Seen” date).

Verified Confidence: Elevating Communication with IP Quality Score’s Email Address Verification

Our reputation scoring detects high-risk email addresses based on recent abuse and activity. Unlike other email verifiers that use stale blacklists, ours are updated in real-time to catch the newest disposable and temporary email services, parked domains, and other suspicious activities that fraudsters use to bypass spam filters.

We also offer a wide range of additional email security checks to prevent data leaks and other malicious activity. This includes a check for DNS and MX records that are inconsistent or missing, the ability to ping an IP address and determine its physical location, and more. The API can also return an estimated age of an email based on its first seen date by IPQS, which can be useful in determining the validity of newly created accounts or logins.
