EmailShield

What is EmailShield?

EmailShield helps teams verify emails, clean lists, and monitor deliverability. It uses real SMTP handshakes, not just DNS checks, so catch-all domains and risky addresses are handled more carefully. The platform also covers blacklist monitoring, DMARC checks, inbox and spam testing, and email health insights in one dashboard. It is built for fast bulk processing and real-time API use, with SDKs, webhooks, and clear developer tools. The service emphasizes privacy, self-hosted proxy infrastructure, and compliance support like SOC 2 Type II, GDPR, and ISO 27001. It is aimed at senders who want better deliverability, fewer bounces, and cleaner data.
