Email Address Fraud Protection — Using Emails for Fraud Detection

Email address fraud prevention is a powerful tool to prevent fake accounts, suspicious payments, and abuse from bad actors online.

Preventing fraud is easy when IPQS is deployed in your stack for assessing risk during account opening or login, or analyzing transaction risk during checkout.

Advanced Email Address Analytics for Fraud Prevention

Streamline fraud detection and verification of users and payments through your platform with powerful email address analytics, totaling to over 30 email reputation signals that prevent fraud and abusive behavior to calculate an email risk score. IPQS enhances your team's awareness of bots, fake accounts, and suspicious payment with both positive and negative signals for comprehensive email fraud protection.

Improve identity verification and fraud prevention with real-time email address assessment using the industry's most advanced email address intelligence. IPQS calculates an overall Fraud Score which can be used to quickly block or flag suspicious accounts and high risk payments. While many email addresses can look legitimate to the naked eye, these are some of the factors that IPQS machine learning algorithms use to detect fraudulent email addresses:

  • Email Address Age / Longevity — Aged email addresses typically represent a higher quality user. Due to the large amount of email addresses compromised online, it is possible for fraudsters to easily access compromised email addresses online and reduce the effectiveness of this signal.
  • Domain ReputationEmail address domain reputation is a powerful signal for quality, especially when a fraudster is using a disposable domain or any type of abusive mail service. Known fraudulent email domains can quickly elevate a score to 90 or higher.
  • Email Address Activity — The velocity and frequency that an email address is used on the web can help indicate if the email address is engaging in legitimate behavior, such as account registrations, purchases, etc. These signals help indicate that a real user is actually using the email address, rather than a fraudster that is cycling through 30+ different email addresses for malicious purposes.
  • Email Address Identity Verification — Append data such as first and last names, location, phone number, and similar identity data points that can help verify the user is legitimately associated with the email address. Reverse identity verification checks and live appends enhance any fraud detection solution to quickly verify an email address matches a user.
  • Suspicious Patterns — Weird characters, unusual patterns, excessive numbers, swear words, and similar behavior can help identify bad emails that likely represent a high risk user or payment. An email risk score is the perfect defense against fraudulent transactions or registrations.
  • Email Blacklists & Honeypot Network — Access the industry's best email address blacklist to block malicious emails associated with fraudulent behavior, such as chargebacks, bots, fake registrations, etc. Benefit from one of the largest honeypot networks of compromised accounts and high risk user data that can supplement existing fraud detection rules.
  • Email Validation - Combine email address fraud prevention with world class email validation services. Advanced risk analysis paired with email verification identifies fake or inactive email accounts.

How Does Email Fraud Prevention Work?

IPQS email address intelligence incorporates each of the quality checks above to identify email address reputation issues for personal email addresses and business accounts alike. This verification process also includes a deep email blacklist check based on behavior across our threat network and data from other clients that have recently reported fraudulent behavior back into our ecosystem through Fraud Fusion™.

Deep machine learning models put the final touches on our fraud scores which are based from 0 to 100. Fraud Scores >= 90 indicate high risk behavior and confirm that abusive behavior has recently been reported. Accurate fake email detection can identify email address fraud in just a few hundred milliseconds. Perform on-demand fraud email address checks through our user dashboard or live API. Our advanced custom rule sets make it easy to adapt our scoring directly to your audience, for better detection of fraudulent emails.

Email Address Fraud Prevention Analysis

IPQS makes it easy to identify high risk behavior simply by analyzing an email address. Addresses with a short lifetime of activity or those without healthy email reputation behavior are most concerning from a fraud prevention point of view. Fraudulent emails recently reported in our blacklists will also have elevated risk scores if multiple partners have reported abusive behavior. IPQS email address intelligence is easy to deploy and will quickly stop fraudulent chargebacks and fake leads or sign ups with real-time email address fraud protection.
