Validate Email Addresses in Milliseconds
Comprehensive validation checks designed for modern SaaS applications. From syntax validation to advanced catch-all detection, we've got you covered.
Disposable Email Detection
Block temporary email addresses from 100,000+ known disposable providers. Our database grows organically with new threats, protecting from throwaway accounts.
MX Record Validation
Verify that the email domain has valid mail exchange records and can actually receive messages. Catch typos and non-existent domains before they bounce.
Gibberish & Bot Detection (Beta)
Catch randomly typed emails like asdfjkl@ or auto-generated strings from bots. Our pattern analysis identifies fake signups and keyboard spam, keeping your list clean and authentic.
Role-Based Email Detection
Flag generic addresses like info@, support@, and admin@ that don't belong to real users. Perfect for B2B applications requiring personal email verification.
Corporate Domain Intelligence
Detect public providers and relay services. Distinguish between corporate and personal domains to enforce business email requirements and reduce fraud risk.
Typo Suggestions
Smart suggestions for common email typos (gmial.com → gmail.com). Help users fix mistakes before submission, reducing bounces and improving signup conversion rates.
