As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • analyze_headersEmail header analyzerread-only

    Parse raw email headers: the Received delivery path with per-hop delays, the receiving server's SPF/DKIM/DMARC verdicts, DMARC alignment of the From domain, DKIM signatures, the sending IP, and bulk-sender requirements such as one-click unsubscribe.

  • check_blacklistsDNS blacklist lookupread-only

    Check an IPv4 address against about 18 IP blacklists (SpamCop, Barracuda, UCEPROTECT, PSBL, Mailspike, ...) or a domain against domain blacklists. Each list is verified with its test entries first, so lists that refuse public resolvers (such as Spamhaus) are reported as unavailable rather than clean.

  • check_domainEmail domain health checkread-only

    Run every email-authentication check on a domain (SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI, plus domain and mail-server blacklists) and return a score out of 100, per-check findings and a prioritized fix list. Use this first when asked whether a domain is set up correctly to send email.

  • check_recordCheck one DNS email recordread-only

    Look up and validate a single email DNS record for a domain, explaining each tag. record is one of spf, dmarc, dkim, bimi, mta-sts, tls-rpt, mx. SPF counts the 10-lookup limit; DMARC checks policy, reporting and external report authorization; DKIM sizes the key; MTA-STS fetches the policy file and compares it with the MX hosts; BIMI checks the logo (SVG Tiny PS) and mark certificate.

  • check_spam_wordsEmail copy spam checkread-only

    Scan an email subject and body (plain text or HTML) for spam-trigger phrases by category, ALL-CAPS, exclamation runs, emoji, URL shorteners and image-heavy HTML. Returns a low/medium/high risk reading and, optionally, a rule-based rewrite.
