TXT record lookup

Enter a domain to look up its TXT records.

What is a TXT record?

A TXT record stores arbitrary text against a domain. In practice it powers email authentication (SPF), domain ownership verification for services like Google and Microsoft, and various security policies.

This tool lists every TXT record on a domain so you can confirm your SPF policy, verification tokens, and other entries are present and correct.

Frequently asked questions

What are TXT records commonly used for?+

The most common uses are SPF (email sender policy), domain verification tokens for third-party services, DKIM keys, and site verification for search consoles. DMARC also lives in a TXT record at a specific subdomain.

Is there a limit on TXT record length?+

A single TXT string is limited to 255 characters, but a record can contain multiple concatenated strings. Long values like DKIM keys are usually split across several strings and joined by resolvers.

Can TXT records affect email delivery?+

Yes, significantly. SPF, and the DKIM keys often stored in TXT records, are checked by receiving mail servers. A wrong or missing SPF record can cause your mail to be marked as spam or rejected.
