What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• check_domain_email_setup

  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 em

• check_dmarc

  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DMARC record: whether one exists at _dmarc, its policy (none, quarantine, reject), whether reports are collected, and outdated tags.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_spf

  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.

• check_dkim

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

• check_mx

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

• check_bimi

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

• check_mta_sts

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

• check_blacklists

  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.

• analyze_email_headers

  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_cold_email

  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.

• test_subject_line

  Score a cold email subject line out of 10: length, wording that hurts opens, and spam trigger words, with fixes.

• suggest_sending_domains

  Suggest lookalike sending domains for cold email (so the main domain is never put at risk), with live .com/.net availability. Give a business name or its website.

• guess_email_addresses

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

• generate_spf_record

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

• generate_dmarc_record

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

• generate_dkim_record

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