  • analyze_email_headersEmail header analyzerread-only

    Read the raw headers of a received email: SPF, DKIM and DMARC results, alignment, the delivery path and delays. Use when someone pastes headers and asks why a message went to spam or failed authentication.

  • check_bimiBIMI checkread-only

    Check a domain's BIMI record (logo in the inbox) and whether its DMARC policy is strict enough for BIMI to show.

  • check_blacklistsEmail blacklist checkread-only

    Check whether a domain's sending IPs, or a single IPv4 address, are listed on the major email blacklists (Spamhaus, Barracuda, SpamCop and others), with removal links.

  • check_cold_emailCold email checkerread-only

    Score a cold email (subject and body) out of 10 against the rules Pipefire checks its own emails with: length, reading level, the ask, subject line, and spam-filter wording. Returns each issue with why it matters and how to fix it.

  • check_dkimDKIM checkread-only

    Look up a domain's DKIM public key, trying the selectors Google Workspace, Microsoft 365 and common senders use, plus one you name.

  • check_dmarcDMARC checkread-only

    Check a domain's DMARC record: whether one exists at _dmarc, its policy (none, quarantine, reject), whether reports are collected, and outdated tags. Tells you whether the domain can be impersonated by email.

  • check_domain_email_setupEmail authentication check (MX, SPF, DKIM, DMARC)read-only

    Check whether a domain is set up to send and receive email properly: MX, SPF, DKIM and DMARC in one go, each with pass/warn/fail, what was found, and how to fix it. Use when someone asks why their email goes to spam, whether their domain is set up right, or before sending cold email.

  • check_mta_stsMTA-STS checkread-only

    Check a domain's MTA-STS policy, which forces encrypted delivery of incoming mail.

  • check_mxMX lookupread-only

    List a domain's mail servers (MX records) and which provider handles its email.

  • check_spfSPF checkread-only

    Check a domain's SPF record: whether it exists, is valid, stays under the 10 DNS lookup limit, and ends with a sensible all mechanism.

  • generate_dkim_recordDKIM record generatorread-only

    Format a DKIM public key as the TXT record to publish at selector._domainkey.yourdomain.

  • generate_dmarc_recordDMARC record generatorread-only

    Build a valid DMARC TXT record (to publish at _dmarc.yourdomain) from a policy and report addresses.

  • generate_spf_recordSPF record generatorread-only

    Build a valid SPF TXT record for a domain from the email services it sends with, with warnings about the 10-lookup limit.

  • guess_email_addressesEmail permutatorread-only

    List the likely email address formats for a person at a company domain (first@, first.last@, flast@ ...). Guesses only: verify before sending.
