IPQS has launched a new product designed for organizations requiring high-speed email validation while maintaining complete control over their data: the IPQS Email Verification Database.

This self-hosted solution brings the core benefits of our email verification and risk scoring technology directly to your internal systems. It offers a direct alternative to cloud-based APIs, enabling fast performance, consistent accuracy, and complete privacy.

The Email Verification Database follows the model of our existing IP Reputation Database, which provides on-premise access to IP risk data. These databases offer a comprehensive approach to validating users and traffic sources in real time.

What Is the Email Verification Database?

The IPQS Email Verification Database is a downloadable product that contains our full email verification dataset, refreshed monthly, weekly, or daily (depending on customer needs) and built for local deployment. It allows companies to work with the same data found in our API without making external requests.

The database provides insights into:

     • Temporary and disposable email addresses

     • Spam traps and honeypot

     • Automated or scripted sign-up activity

     • Addresses tied to abusive or suspicious behavior

     • Domain-level issues that impact email deliverability

Your team can integrate this data directly into your systems, allowing for high-volume processing with very low response times.

Who Should Use It?

We created this product for businesses that prioritize control, speed, and data accuracy. Common use cases include:

     • Cybersecurity teams monitoring email risk indicators

     • Email marketing platforms maintaining high-quality mailing lists

     • Financial services preventing fraudulent account creation

     • Lead generation tools filtering out fake or low-value submissions

     • Development teams building internal tools that process email data at scale

Benefits

Full Control Over Data 

By keeping all data on-site, your organization avoids the need to send requests to third-party servers. This approach supports data residency compliance requirements and reduces exposure to privacy risks.

Fast Performance 

Because the data is hosted locally, your applications can access it instantly. This supports real-time checks without network delay, even under high traffic.

Cleaner Email Lists 

Removing invalid or risky addresses before sending improves deliverability and helps maintain a strong sender reputation. The database flags addresses likely to bounce, lowering campaign failure rates.

Detect Fraud at the Source 

The data helps prevent abuse during account creation and other user actions. You can block patterns and domains commonly associated with bots, fraud rings, and fake identities.

Easy Access for Development 

To speed up integration, we provide prebuilt database readers for several languages:

     • Golang

     • PHP

     • Java

     • Python

     • Rust

These libraries help you connect your systems to the database with minimal setup. Your team can use the data in real-time applications, batch processes, or offline audits.

Scalable for Large Workloads

We designed the Email Verification Database to handle large volumes. Whether you’re processing a few thousand entries or millions per day, the data is structured to support fast lookups without bottlenecks.

Daily updates are delivered via secure download or SFTP, allowing you to keep your local copy current. This structure supports frequent use in environments with strict uptime or performance requirements.
