TXT Record Lookup
Look up all TXT records for any domain, classify each record, detect connected services, check email authentication, and export results
Enter a domain to look up its TXT records
See every TXT record classified by type, detect connected services, check email authentication, and export the results.
What is the TXT Record Lookup Tool?
The TXT Record Lookup tool retrieves every TXT record published for a domain and goes further than a raw dump — it automatically classifies each record as email, verification, security, or custom, detects which services are connected (Google, Facebook, Stripe, OpenAI, Microsoft 365, and 30+ more), checks email authentication status (SPF, DMARC, DKIM), and builds a health summary.
TXT records are the catch-all of DNS — they're used for email authentication (SPF, DKIM, DMARC), domain ownership verification (Google Search Console, Facebook, Stripe), security policies (BIMI, MTA-STS), and custom metadata. This tool makes sense of what would otherwise be an unreadable list of strings.
How to Use the TXT Record Lookup
- 1Enter a Domain:
Type or paste any domain and click "Lookup TXT".
- 2Review Detected Services:
A chip list shows every recognized service — email providers, verification platforms, and security tools. Each record is grouped into Email, Verification, Security, or Custom.
- 3Expand Explanations:
Click "What is this?" on any record to see a plain-English explanation of what the record does and which service it belongs to.
- 4Copy or Export:
Copy individual records, copy all at once, or export the full classified results as CSV, JSON, or plain TXT.

Pro Tips
Audit Verification Records
Large organizations accumulate domain verification TXT records for services they no longer use. Review the Verification category and remove stale entries — each one is an unnecessary signal to attackers about your tech stack.
Check All Three
If the Email Authentication row shows a missing record, click it to jump to the dedicated SPF or DMARC checker with the domain already loaded — don't leave gaps in your email security chain.
Export Before Migrating
Before a DNS migration, export all TXT records as JSON. After the cutover, re-run the lookup and compare — any missing record means a service lost its domain verification.
Real-World Applications
IT Admin Auditing
See every service connected to your domain in one view — identify shadow IT, forgotten verifications, and unauthorized SPF includes.
Competitive Intelligence
Check a competitor's TXT records to see which email platforms, verification services, and security tools they use — it's all public DNS data.
DNS Migration
Export all TXT records before switching DNS providers, then verify after the cutover that nothing was lost — especially verification records that break silently.
Common TXT Record Types
A reference for the most common TXT records you'll find in production DNS — useful for identifying records by hand when reviewing raw zone files.
