About the TXT Record Lookup
The TXT Record Lookup lists every TXT entry of a domain and labels the recognizable ones — SPF, DMARC and verification tokens. For a parsed, human-readable view of the mail policies, use the dedicated SPF Checker and DMARC Checker.
Free-form text in DNS — most commonly SPF mail policies, domain-ownership verification tokens (Google, Microsoft …) and DKIM public keys.
A single TXT string is limited to 255 characters; longer values (like DKIM keys) are published as multiple quoted chunks that receivers join.
They live on subdomains: selector._domainkey.example.com (DKIM) and _dmarc.example.com — check the latter with the DMARC Checker.
