Everything you need to know about SanitizeMail and our proprietary verification engine.
Unlike standard verifiers that return "Unknown," SanitizeMail uses a proprietary SMTP handshake. We engage with mail servers in real-time to detect specific responses that indicate if a mailbox exists, providing a definitive "Safe" or "Invalid" status for catch-all domains.
Toxic entities include disposable providers, known spam traps, and domains associated with bot activity. Removing these is critical as they can instantly damage your sender reputation and lead to domain blacklisting.
Extremely fast. Average latency is <50ms for syntax checks. SMTP verification resolves in 1-3 seconds. Built on a Go-based architecture, our API handles millions of concurrent requests without throttling or performance degradation.
Absolutely. We use 256-bit bank-grade encryption and a strictly transient processing model. We never sell or share your data, and we do not store lists longer than necessary for verification, ensuring full GDPR compliance.
Yes. Upon registration, you automatically receive 100 free verification credits to test our accuracy. No credit card is required to start testing the SanitizeMail engine.
