The IPQS email verification API validates email addresses through on-demand lookups to mailbox providers such as Gmail.com, Yahoo.com, and Hotmail.com. Append important data to any email address, including identity details, fraud scores, validation status, spam trap detection, and even disposable email detection.

Our email checker technology performs the email verification process through deep checks that look at an email address from all angles. It features advanced mailbox verification checks for issues like spam traps, catch-all domains, syntax errors, invalid addresses, and other types of incorrect email addresses.

Analyze email address reputation in real-time with email risk analysis, including the email account creation date using an estimate of the email age based on when IPQS first discovered the account.

IPQS provides advanced email address fraud prevention to validate new users, logins, and payments. In addition to detecting disposable email services and parked domains, IPQS can also identify perfectly valid email addresses that have recently engaged in abusive behavior. IPQS can detect email addresses recently involved with chargebacks, fake account creation, account takeover, SPAM, trial abuse, and high-risk behavior through our honeypot threat network and partner feedback program.

Routine email list cleaning with the IPQS email scrubbing API is a best practice use by large brands and mailers to ensure healthy deliverability rates. Major email service providers like Gmail.com, Yahoo.com, Hotmail.com, AOL.com, Outlook.com, and other large providers worldwide will block senders with high bounce rates and poor domain or IP address reputation. Cleaning your email lists with the email verification API will remove spam traps, complainers, and invalid emails, which prevent inbox bounces and ensures your mail reaches the inbox and not the spam folder.

Imagine the relief of not having to manually clean your data. An email verification service can do just that, acting as a data hygiene tool to improve the quality of data captured through lead capture forms or during user registration. It can identify and correct typos, remove invalid email addresses, and even spot suspicious or malicious emails, such as disposable or temporary ones, and spam traps.

An email verification API can substantially increase email deliverability rates by reducing bounce rates and invalid addresses, which improves inbox placement. Mail service providers trust senders with low bounce rates, high open rates, healthy DNS records (like SPF, DKIM, rDNS, and PTR), and similar positive behavior metrics resulting from email verification tools. You can build up these positive sender reputation signals with an email verification service that can also identify mistyped or false entries from incorrect submissions due to human error or fraud.
