Standard verifiers mark "Catch-all" emails as "Risky" or "Unknown".

SanitizeMail is different. We analyze server patterns to give you a definitive Safe or Unsafe status, unlocking 30% more leads for your business.

Frequently Asked Questions

Everything you need to know about SanitizeMail and our verification process.

How do you verify "Catch-All" emails accurately?

Unlike standard verifiers that return "Unknown" for catch-all domains, SanitizeMail uses a proprietary SMTP handshake method. We engage with the mail server in real-time to detect specific server responses that indicate whether a mailbox truly exists, giving you a definitive "Safe" or "Invalid" status.

What counts as a "Toxic" domain?

Toxic domains include disposable email providers (like 10minutemail), known spam traps, and domains associated with bot activity. Removing these is critical because sending emails to them can instantly damage your sender reputation and get your domain blacklisted.

How fast is the API integration?

Extremely fast. Our API has an average latency of under 50ms for syntax and domain checks. For deep-level SMTP verification, results are returned in real-time (usually 1-3 seconds), ensuring your user signup flow remains smooth and frictionless.

Do you offer a free trial?

Yes! When you sign up, you automatically get 100 free verification credits to test our accuracy. No credit card is required to start.

Is my data secure and GDPR compliant?

Absolutely. We use 256-bit bank-grade encryption for all data transmission. We are fully GDPR compliant and never sell, share, or store your uploaded email lists longer than necessary for processing.
