Free TXT Checker
Validate Your TXT Records & Domain Verification
Check every TXT record published for your domain and quickly detect configuration errors, duplicate entries, and conflicting records.
Enter your domain to perform a live TXT lookup and view SPF, site verification records, and connected services in one place.
About Free TXT Record Checker by DMARKOFF
Our Free TXT Record Checker queries authoritative DNS servers and shows every TXT record published at your domain apex.
It shows each record's type, provider, TTL, and full value, so you can quickly verify that SPF, site verification, and other domain records are configured correctly.
If it detects an issue, such as multiple SPF records or a DMARC record where one shouldn't be, you'll see the exact fix to apply.
What Is a TXT Record?
TXT (Text) records are DNS entries that contain arbitrary text data associated with a domain. They:
• Prove domain ownership to services like Google, Microsoft, and Facebook
• Publish SPF policies that authorize which servers can send email for your domain
• Store verification strings, security policies, and other configuration data
Larger domains often accumulate dozens of these records over time, one per connected tool or service, which makes it easy for stale or duplicate entries to go unnoticed.
TXT records work alongside SPF, DKIM, and DMARC, the standards for email authentication. Without properly configured TXT records, domain verification can fail, and outgoing email may be rejected or marked as spam.
Example of Valid TXT Records
A domain can publish multiple TXT records for different purposes at the same time. Each record has a type, provider, and value that receiving systems or verification services read directly:
In this example:
Type (site-verification) – A TXT record used to prove domain ownership to a specific provider (Google, Facebook, etc.).
Type (spf) – Publishes the domain's SPF policy, authorizing which mail servers are allowed to send on its behalf. SPF records may use include: to reference another domain's policy, or redirect= to delegate the entire policy elsewhere.
Type (other) – Records that don't match a recognized site-verification or SPF pattern, such as SSO configuration, security scanner tokens, or custom challenge strings from connected tools.
Provider (google, facebook, —) – Identifies which service the record belongs to, when identifiable; SPF and "other" records often show no single provider.
TTL (5 min) – Defines how long DNS resolvers cache the record before checking for updates again.
What the TXT Record Checker Detects
Our Free TXT Record Checker analyzes your TXT configuration and highlights potential issues in a clear, structured report:
✓ Confirms apex TXT records exist and retrieves them
✓ Confirms the correct number of SPF records (multiple SPF records at once cause failures)
✓ Confirms no DMARC record is unintentionally published at the apex TXT level
✓ Identifies site-verification records by provider (Google, Facebook, etc.)
✓ Flags malformed or duplicate TXT entries
Results include each TXT record's type, provider, TTL, and full value, giving you a complete view of your domain's TXT configuration. When a check fails, you'll get the specific fix to apply.
Benefits of Regular TXT Checks
• Confirm domain ownership stays verified across all connected services
• Catch duplicate or conflicting SPF records before they break email authentication
• Detect stray or misconfigured DMARC entries
• Reduce the risk of failed verification or rejected outgoing mail
• Validate changes after DNS updates or provider migrations
• Quickly audit TXT records across multiple domains
• Spot leftover records from tools or integrations you no longer use

FAQ
A TXT record lookup retrieves the text records published in a domain's DNS. It shows verification strings, SPF policies, and other data services use to confirm ownership or authentication rules.
TXT records prove domain ownership to third-party services and publish policies like SPF that control which servers can send email on your behalf. Missing or incorrect records can break verification and email delivery.
Yes. Many domains publish multiple TXT records for different providers and purposes at the same time, such as several site-verification strings alongside an SPF record.
Yes. Duplicate SPF records, malformed syntax, or missing entries can cause outgoing email to fail authentication and be rejected or sent to spam.
Check TXT records after any DNS change, provider verification, or email service migration, and periodically as part of routine DNS maintenance to catch unauthorized modifications.
The checker identifies exactly what's wrong, such as duplicate SPF records or a misplaced DMARC entry, and shows the specific fix to apply. Update the relevant DNS record, then rerun the check to confirm it passes.
A TXT record can contain any text string up to the length limits set by your DNS provider. Common uses include SPF policies (starting with v=spf1) and site-verification strings issued by the service requesting proof of ownership.
