  • check_domainCheck a domain mail configurationread-only

    Audit a domain's email setup in one call: MX records, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, DNSSEC and BIMI, graded A-F with a fix for every problem found. Use this to answer "can this domain send and receive mail" or "why do our messages land in spam". Takes a domain (example.com), not an email address. The default answer summarises every section; pass `section` to get the full records and findings of one of them.

  • check_spfCheck a domain SPF recordread-only

    Fetch and analyse the SPF record of a domain: the raw record, its mechanisms, lookup count and common misconfigurations. Use check_domain instead when the question is about overall deliverability rather than SPF specifically.

  • validate_emailValidate one email addressread-only

    Check whether a single email address is deliverable: syntax, domain MX records, disposable-domain database and a live SMTP mailbox probe. Status is one of "Valid", "Not Valid", "Unknown". Unknown means the mailbox could NOT be checked (catch-all domain, greylisting, blocked SMTP port) - it is NOT a bad address. Never delete, reject or report Unknown addresses as invalid; present them separately and let the user decide. Use validate_emails instead when you have more than one address.

  • validate_emailsValidate a list of email addressesread-only
