About

BillionVerify is a professional email verification service built to solve one problem: bad email data costs businesses money. Every bounced email hurts sender reputation, wastes marketing spend, and skews campaign analytics. We built BillionVerify to give teams of every size access to accurate, fast, and affordable email verification. Since launch, our platform has processed over 1 billion email verifications for businesses across 200+ countries, covering everything from single API lookups at signup to bulk list cleaning of millions of records.

About

EmailShield is an email verification and deliverability platform that guarantees 99.8% verified accuracy through real SMTP handshakes — not DNS-only lookups used by legacy tools. Multi-step verification includes syntax checks, MX record validation, and real-time mailbox existence confirmation without sending actual emails. Bulk processing handles up to 100,000 emails per minute. The platform runs on self-hosted proxy infrastructure with zero third-party dependencies and rotating egress IPs. Features include 24/7 blacklist monitoring across 100+ global blacklists, DMARC/SPF/DKIM monitoring with AI-based insights, AI data enrichment, and free full scan diagnostics. Single API endpoint with SDKs for Python, Node.js, and PHP. Pricing starts at $19/mo for 10,000 credits with pay-as-you-go from $0.00018 per email — up to 75% cheaper than ZeroBounce, MillionVerifier, and Hunter. SOC 2 Type II, GDPR, and ISO 27001 certified with EU data residency options. 40,000 free credits on sign-up.
