Upload. Clean. Send.

A streamlined 3-step workflow built for high-volume senders who value their time.

01

Upload Your List

Drag and drop your CSV or connect via API. We handle files of any size with instant initialization.

02

Real-time Verification

Our engine runs 20+ checks — syntax, domain validity, catch-all detection, and live SMTP handshakes.

03

Export & Send

Download your pristine list. Invalid and risky emails are cleanly separated for pure deliverability.

Built for operations that cannot fail.

While other tools rely on stale cached databases, EmailValidator performs deep, real-time SMTP handshakes to verify inbox existence without ever sending a message.

  • Enterprise-Grade Security

    SOC2 Type II and GDPR compliant. Data encrypted at rest and in transit, auto-purged after 30 days.

  • Anti-Greylisting Technology

    Advanced retry logic handles mail servers that employ greylisting, ensuring accurate results where others return 'unknown'.

  • Proprietary Risk Scoring

    Every email gets a risk score based on syntax patterns, domain age, and network-wide bounce data.

POST api/v1/verify200 OK
{
  "email": "sarah@example.com",
  "status": "valid",
  "score": 0.98,
  "checks": {
    "syntax": true,
    "mx_found": true,
    "smtp_check": true,
    "catch_all": false,
    "disposable": false
  },
  "latency_ms": 14
}

Every edge case, covered.

Our proprietary engine goes deeper than simple ping tests to ensure your messages land in primary inboxes.

Disposable Email Detection

Instantly flags temporary and throwaway email addresses that ruin engagement metrics.

Catch-all Verification

Advanced heuristics determine if a domain accepts all mail, mitigating hidden bounce risks.

Role-based Filtering

Identifies generic addresses (admin@, support@) that rarely lead to real conversions.

Spam Trap Removal

Cross-references known honeypots to protect your sending IPs from blacklisting.

MTA Validation

Deep SMTP handshakes verify the recipient server is actively accepting mail in real time.

Risk Score per Email

Every address receives a 0–1 risk score based on syntax, domain age, and historical data.
