What Information Do You Get?
✔️ Email Validity Check
We verify if the domain has proper email infrastructure (MX records) to actually receive emails. This prevents users from signing up with fake or non-functional email addresses that will bounce when you try to contact them.
🗑️ Disposable Email Detection
Instantly identifies temporary email services that people use to bypass your signup process. These "10-minute email" services are often used by people who want access without commitment, leading to poor user engagement and inflated signup metrics.
📧 Public Email Provider Detection
Flags common personal email services like Gmail, Yahoo, and Hotmail. While not necessarily bad, this helps you understand your user base and can indicate whether someone is signing up personally vs. professionally.
⚠️ Spam & Abuse Detection
Identifies domains frequently associated with fraudulent activity, spam, or abusive behavior. Blocking these proactively protects your platform's reputation and prevents potential security issues.
🎓 Academic Institution Recognition
Automatically detects university and educational institution domains. Perfect for offering student discounts, educational pricing, or targeting academic users with specialized features.
Why Email Validation Matters for Your Business
Reduce Costs
Stop paying for fake users who will never convert. Disposable email users rarely become paying customers, so filtering them out improves your cost per acquisition and helps you focus marketing spend on real prospects.
Better Analytics
Get accurate user metrics that actually matter. When your signup data isn't polluted with fake accounts, you can make better business decisions based on real user behavior and engagement patterns.
Prevent Abuse
Block bad actors before they can exploit your free trials, create multiple accounts, or engage in fraudulent activity. Protecting your platform's integrity saves time and resources in the long run.

Real-Time Infrastructure Checks
We verify the domain's email infrastructure by checking MX records and other DNS settings to ensure emails can actually be delivered to that domain.

Frequently Asked Questions
What's the difference between disposable and public email providers?
Disposable emails are temporary services designed to be thrown away after a short time (like 10minutemail.com). Public providers like Gmail are legitimate, permanent email services that many people use for personal communication. Both serve different purposes in your user analysis.
How often is your database updated?
Our database is updated multiple times per day using automated systems that scan the web for new disposable email services and spam domains. This ensures you're always protected against the latest threats and abusive providers.
Should I block all disposable email addresses?
It depends on your business model. Many companies block them for free trials and premium content but allow them for newsletters or basic account creation. The key is having the information to make informed decisions based on your specific needs.
What about privacy and data protection?
We only analyze domain names, not full email addresses or personal information. Our service is designed to be privacy-friendly and compliant with data protection regulations. We don't store or process any personal data.
