Core Verification Modules

Four-layer validation architecture

RFC 5322 Syntax Validation

Parses address structure against strict RFC 5322 standards. Catches malformed strings, invalid character sets, and excessive subdomain nesting before they hit your pipeline.

Explore Syntax Engine

DNS & MX Record Verification

Queries authoritative DNS servers to confirm domain legitimacy and mail exchange routing. Flags disposable domains, catch-all configurations, and expired TLDs in under 200ms.

View Domain Checks

SMTP Mailbox Existence

Performs safe, non-intrusive SMTP handshakes to verify actual inbox availability. Detects greylisting, throttling limits, and silent drops without triggering spam filters.

Check SMTP Protocol

Role & Catch-All Detection

Identifies generic addresses like support@, info@, and admin@ that hurt engagement metrics. Separates role-based accounts from personal inboxes to optimize deliverability scores.

Performance Metrics

Built for high-throughput pipelines

VeriMail processes up to 15,000 requests per second across distributed edge nodes. Our stateless architecture guarantees consistent latency and zero data retention after verification.

Latency & Throughput

Average response time of 180ms for full-stack validation. Sustained throughput of 500M emails per month per enterprise tier with automatic horizontal scaling.

Data Privacy & Compliance

GDPR and CCPA compliant by design. Verification logs are purged after 24 hours. SOC 2 Type II certified infrastructure with AES-256 encryption in transit and at rest.

Integration Standards

RESTful API with JSON and CSV batch endpoints. Pre-built SDKs for Python, Node.js, and PHP. Webhook support for async queue processing and real-time status callbacks.

Platform Comparison

VeriMail vs. Legacy Validation Tools

VeriMail Engine

Continuous live verification with dynamic threat intelligence feeds. Real-time bounce prediction algorithms reduce hard bounces by 99.4%. Dedicated account managers for custom rule sets.

Upgrade to VeriMail

Traditional Batch Scanners

Static database matching with outdated MX records. Prone to high false-positive rates on corporate domains. Manual CSV uploads delay campaign launches by 24-48 hours.

Basic Regex Filters

Surface-level pattern matching that misses non-existent mailboxes and catch-all traps. Increases bounce rates over time as domains expire. Zero deliverability optimization.
