DMARC Rollout Planner

Bulk email authentication audit. Parses SPF, DMARC, and DKIM records, returns deliverability score (0-100), and step-by-step remediation actions per domain.

Domain Security & Email Deliverability — DNS, SPF, DMARC, DKIM

ryanclinton/dns-record-lookup

Audit a domain portfolio for email spoofing, broken SPF, DMARC enforcement, DNSSEC and shadow-SaaS senders. Returns a posture score, what to fix first, vendor dependencies and drift alerts — not just records. Bulk DNS / SPF / DMARC / DKIM lookup, no API keys.

DMARC Report Analyzer — Email Security & SPF/DKIM

perryay/dmarc-report-analyzer

Parse and analyze DMARC forensic and aggregate reports. Get SPF/DKIM alignment, identify spoofing attempts, and monitor email authentication health.

MX Lookup — Email DNS, SPF, DKIM & DMARC

junipr/mx-lookup

Check MX, SPF, DKIM, DMARC, TXT, CAA, and email DNS records in bulk with validation findings and deliverability diagnostics.

One-call security report card per domain — WHOIS, DNS, SPF/DMARC email auth, SSL/TLS expiry, with a posture score and grade. No login.

Audit any domain's email authentication (MX, SPF, DMARC, BIMI, DKIM) and get a deliverability score with actionable issues.

Bulk-check domains for email setup & authentication over DNS: MX + provider, SPF, DMARC policy, DKIM selectors, with a deliverability score. One JSON row per domain.

Run an email authentication check on up to 100 domains at once. Reads public DNS for DMARC, SPF, MX and the DKIM selectors you name, parses the p, sp and RFC 9989 np policies, and returns a 0-100 score per domain with the raw records and the anti-spoofing fixes to apply first.

Email & Domain Auth Checker: MX, SPF, DKIM & DMARC

apifmcpfactory/email-domain-checker

Checks an email or domain's deliverability signals from DNS alone: MX, SPF, DKIM, DMARC, plus disposable and role-address flags. No SMTP, no mailbox ping. It reports auth-record posture, not mailbox existence. $0.005 per input checked.

cottony_brittlegill/domain-mailhealth-bulk

Bulk email deliverability and security audit: MX, SPF, DMARC and DKIM (common selectors) for up to 100,000 domains in one normalized JSON per domain, with an A-F grade and actionable issues. Failed lookups are never charged.
