How to use TXT Record Lookup
The TXT Lookup retrieves all the TXT records published in a domain’s DNS — free-form text entries that carry a surprising amount of important configuration, from email-authentication policies like SPF and DMARC to the verification strings services use to prove you own a domain. Because so many systems hide critical settings in TXT records, being able to read them all at a glance is invaluable for debugging email delivery, confirming a verification has been added, or auditing what a domain has published. Use this tool to list every TXT record and inspect its exact contents.
- Enter the domain whose TXT records you want to read.
- Click Lookup to fetch all TXT records from DNS.
- Scan the list for SPF, DMARC and verification entries.
- Confirm any record you recently added appears as expected.
- Check for duplicate or conflicting records that cause errors.
What lives in TXT records
TXT records are the catch-all of DNS, holding plain text that other systems interpret. The most common are email-related: an SPF record beginning v=spf1 lists who may send mail for the domain, and a DMARC record at _dmarc sets policy for handling failures. Many services — Google, Microsoft, search consoles and countless SaaS tools — also ask you to add a verification TXT record to prove ownership. Because they share the same record type, listing all TXT records together is the quickest way to see a domain’s full configuration footprint.
| Starts with | Purpose |
|---|---|
| v=spf1 | SPF — authorised mail senders |
| v=DMARC1 | DMARC policy (at _dmarc) |
| google-site-verification | Domain ownership proof |
Avoiding the duplicate-SPF trap
One TXT mistake causes more email trouble than any other: publishing two SPF records. The specification permits only a single SPF record per domain, and when two exist receivers may treat the result as invalid, undermining the protection SPF is meant to provide. The fix is to merge all senders into one v=spf1 record rather than adding a second. Listing every TXT record makes such duplicates obvious at a glance, alongside any stale verification strings left over from services you no longer use, which are safe to remove once confirmed unused.
