TXT record lookup
Enter a domain name. Results list TXT strings published at the apex (not subdomains unless specified).
What this checks
All TXT records at the apex domain, record length warnings, and highlights for email-related prefixes.
Why it matters
SPF, DKIM selectors, DMARC, BIMI, and domain verification all use TXT. A single lookup shows the full TXT picture.
Results
Common issues
- Multiple SPF TXT records causing PermError.
- Verification TXT records left behind after migrating providers.
- TXT strings split incorrectly across DNS host panels.
How to fix
- Consolidate to one SPF record and move verifications to dedicated subdomains where possible.
- Use provider-specific SPF/DKIM/DMARC checkers after reviewing raw TXT.
