TXT Lookup
Return every TXT record for a domain, with automatic classification for SPF, DMARC, DKIM, MTA-STS, BIMI and vendor verification tokens.
About the TXT Lookup Tool
The TXT Lookup tool returns every TXT record published for a domain and automatically classifies each one — SPF, DMARC, DKIM, MTA-STS, TLS-RPT, BIMI, or a vendor verification token. TXT records are the most overloaded record type in DNS: they carry email authentication policy, domain-ownership proofs for dozens of SaaS platforms, and arbitrary human-readable notes. A single misplaced or duplicated TXT can quietly break inbox delivery, invalidate a SaaS integration, or leak information about your stack.
We query Cloudflare's DoH endpoint on the edge so results are fast and consistent, then re-assemble the multi-string TXT values the DoH JSON API returns as separately quoted chunks — the same normalization step `dig +short TXT` performs on the command line. Classification is done by pattern-matching well-known prefixes (`v=spf1`, `v=DMARC1`, `v=DKIM1`, `v=STSv1`, `google-site-verification=`, `MS=`, `apple-domain-verification=`, `stripe-verification=`, and 15+ more).
Use TXT Lookup when auditing a new domain, cleaning up leftover verification tokens from decommissioned tools, hunting a rogue second SPF record that's silently failing your mail, or verifying that a vendor's TXT was published correctly to the right label. Pair with our SPF Checker, DMARC Checker and DKIM Checker for deep validation of each email-auth record.
