SanitizeMail was built by engineers tired of "Unknown" results. We developed a proprietary engine to crack the code of Catch-all Servers and Toxic Domains.
Two years ago, we realized that 30% of business emails were being marked as "Unknown" by standard verifiers. These were Catch-all domains. Marketers were deleting them to be safe, losing millions in potential revenue.
We refused to accept "Unknown" as an answer.
We spent 18 months building SanitizeMail—a verification engine that performs deep SMTP handshakes to determine if a catch-all inbox actually exists, without sending a single email.
We rely on data, not guesses. Our infrastructure handles millions of requests daily.
We don't use stale databases. Every email check is performed live against the recipient's mail server at that exact second.
Our blacklist of disposable domains and spam traps is updated hourly to protect your sender reputation score.
Your data is encrypted in transit and at rest. We automatically purge uploaded lists after processing for your privacy.
