Features of EmailShield

Unmatched Accuracy

EmailShield guarantees an exceptional 99.8% verified accuracy by conducting real SMTP handshakes rather than relying on DNS-only lookups. This ensures that catch-all domains are accurately classified, preventing wasted efforts on invalid addresses and maximizing your campaign's effectiveness.

Real-Time Heuristic Analysis

With sub-2-second verification times and the capability to process up to 100,000 emails per minute, EmailShield offers real-time API access that allows for seamless integration into your existing workflows. This means you can validate emails instantly as leads are captured, keeping your lists clean and reliable.

Self-Hosted Infrastructure

EmailShield operates on a self-hosted infrastructure, meaning that your data remains secure within its own network. The use of rotating egress IPs protects your verification requests from being rate-limited by email providers, ensuring consistent performance and reliability.

Comprehensive Blacklist Monitoring

EmailShield provides real-time monitoring across over 100 global blacklists, alerting you instantly if your domains or IPs are listed. This proactive approach allows you to take corrective actions before your email deliverability suffers, maintaining your sender score and reputation.
