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.

About

SubsiMail is a self-hosted cold email sequencing platform. Prospect lists, templates, connected inboxes, and all campaign data live in your own database, not a third-party SaaS. It's built as a self-hosted alternative to Instantly, Smartlead, lemlist, and Apollo, with flat per-inbox pricing instead of per-seat fees, full data ownership and export, no content review, and no third-party access to your contacts or campaigns. Runs as a single Docker container on any $5 VPS. Connect Gmail, Outlook, or any SMTP/IMAP inbox; build multi-step sequences with merge fields and reply detection; manage per-user roles (admin/manager/view-only) with a full audit trail; and integrate via a REST API with personal API keys. The first connected mailbox is free forever.
