#deliverability

Checks email domain deliverability via DNS: SPF, DKIM, DMARC, MX record validation, DNSBL blacklist lookup across 10 lists, RDAP/SOA domain age, and a weighted 0-100 composite score. Built for Clay, GTM, and outbound workflows.

Enterprise-grade, real-time email verification in a straightforward way. Prevent bounces by checking any email against format rules, DNS records, disposable address lists, catch-all detection, and live SMTP—and get back a structured result your agent can act on immediately.

Email-deliverability tools for AI agents — 12 MCP tools across email verification, DNSBL across 50 zones, SPF/DKIM/DMARC analysis, spam-trap heuristic scoring, domain intelligence, and email finder. Free tier with no credit card. MIT licensed. Drops into Claude Desktop and Cursor via npx.

DMARKOFF MCP connects your DMARC monitoring data to AI assistants — Claude, ChatGPT, Cursor, Windsurf — via the Model Context Protocol. Instead of opening a dashboard and building filters, you ask questions and get real answers backed by actual data. Ask which domains dropped in compliance, why SPF is failing on a specific domain, which senders are causing DKIM failures, or whether yesterday's traffic looks anomalous compared to the 14-day baseline. The AI picks the right tool, queries your account data, and gives a concrete answer with numbers and actionable recommendations. 17 tools covering the full diagnostic flow: project overview, domain health, SPF/DKIM records, compliance stats, daily timeline, sending source analysis (by ISP, IP, hostname, or reporter), anomaly detection, geo breakdown, and live DNS checks for any domain — no account needed for DNS tools. Access is scoped to your DMARKOFF account via API key authentication with OAuth 2.1 support. All tools are read-only.
