TXT Record Lookup

All TXT records, with SPF and verification strings highlighted.

How it works

See every TXT record on a domain, with SPF and verifications named

TXT records carry your SPF policy, Google, Microsoft and Meta ownership proofs, and many API verification strings. Enter a domain and we fetch all TXT records live, join multi-part strings back together, identify what each one is for and check the two that break email: duplicate SPF records and SPF lookups over the ten-lookup limit. We also look at _dmarc for the DMARC policy so you get the complete picture.

Results appear here after you click Look up TXT records.

How this works

1
Fetch and reassemble
TXT answers arrive as quoted chunks; we join them back into the original strings.
2
Label each record
Over thirty known prefixes identify SPF, DMARC, DKIM and vendor verification strings.
3
Check SPF and DMARC
Duplicate SPF, lookup count, the 'all' qualifier and the DMARC policy are tested against the standards.

Frequently asked questions

What are TXT records used for?: TXT records hold arbitrary text that other systems read. The common uses are SPF (which servers may send your email), DMARC and DKIM for email authentication, and one-time ownership proofs such as google-site-verification when you connect a domain to a service.
Why do I have two SPF records and why is that bad?: Usually one came with your website host and another with your email provider. The SPF standard requires exactly one v=spf1 record; with two, receivers return permerror and your mail fails authentication. Merge the include terms into a single record ending in ~all.
Can I delete old verification TXT records?: Often yes, but some services re-verify periodically (Google Workspace, Microsoft 365, Meta) and will lose access to the domain if the record disappears. Keep records for services you still use and remove the rest.
How long should TXT records be?: A single string is limited to 255 characters, but a record can contain several strings which resolvers join. Your DNS host normally splits long values for you. Keep SPF under 255 characters where you can for compatibility.
How long until a new TXT record is visible?: Usually within minutes once the record is saved, though resolvers that cached a 'no record' answer keep that for the negative-cache TTL (often 1 to 24 hours). Verification services typically retry automatically.
