Everything you need to know about our email validation service.
Our API checks multiple data points: email syntax format, domain DNS records, MX (mail exchange) server configuration, and compares against our database of disposable email providers. The entire process takes under 100ms and no email is ever sent to the address being validated.
Our validation achieves 99.5%+ accuracy for detecting invalid, disposable, and role-based email addresses. No service can guarantee 100% accuracy since some email servers intentionally mislead verification attempts for privacy reasons.
No. We take privacy seriously. Email addresses are processed in real-time and are never written to disk or logged. We are fully GDPR, CCPA, and PIPEDA compliant.
Single validation checks one email at a time via our REST API with instant results. Batch validation allows you to upload a CSV file with up to 100,000 emails. Results are processed in parallel and available for download as a CSV report.
Absolutely! Our free plan includes 100 validations per month so you can thoroughly test the API. No credit card required. When you're ready, upgrade to a paid plan seamlessly.
You'll receive email notifications at 80% and 100% of your monthly limit. If you exceed the limit, validation requests will return an over-quota error until the next billing cycle or until you upgrade your plan.
Yes, our validator supports international email addresses including Unicode characters, internationalized domain names (IDNs), plus addressing (+ tags), and all standard sub-addressing formats across all major email providers.
You can generate unlimited API keys from your dashboard. Each key has a name for identification and can be revoked individually. We recommend using separate keys for development, staging, and production environments.
