TXT Record Lookup

TXT Records

List every TXT record on a domain

We'll query authoritative nameservers and return every TXT record at the domain apex, classified by purpose.

DNS Resolver

Most domains return the same records on every resolver — the choice matters during DNS propagation, or when a filtering resolver blocks a domain.

What is a TXT record & how it works

How domains publish policy and verification data

TXT records store arbitrary text on a domain's DNS. They aren't used for routing — instead they let a domain publish machine-readable policy and verification data that other systems read, such as SPF, DKIM and DMARC for email, or ownership-verification tokens.

This lookup returns every TXT record at the domain apex, joins multi-string records, and classifies each by purpose so you can see what a domain is publishing at a glance.

SPF
A v=spf1 TXT record listing which servers may send mail for the domain.
DKIM
A public key (in a selector subdomain) used to verify signed email.
Verification
Tokens that prove domain ownership to Google, Microsoft and other services.

How to use this tool

List a domain's TXT records in four steps
1
Enter a domain
Type the domain whose TXT records you want to list, e.g. example.com.
2
Pick a resolver (optional)
Open Advanced Settings to query a specific public resolver such as Google (8.8.8.8) or Cloudflare (1.1.1.1).
3
Run the lookup
Click Check TXT Records to query the authoritative nameservers for every TXT record at the apex.
4
Review the results
Read each record and its classified purpose (SPF/DKIM/DMARC/verification), plus the diagnostics and recommendations.

Frequently asked questions

Common questions about TXT records
5 Q&A

A TXT record stores free-form text in DNS. It's widely used to publish email-authentication policies and domain-ownership verification tokens.

The most common uses are SPF (which senders are allowed), DKIM (email signing keys), DMARC policy, and verification tokens for services like Google Workspace and Microsoft 365.

Yes — a domain usually has several. However, it must have only one SPF record; multiple SPF records are invalid and break mail authentication.

DNS limits a single string to 255 characters, so long values (like DKIM keys) are published as several quoted strings that resolvers join back together.

DKIM records sit at selector._domainkey.example.com and DMARC at _dmarc.example.com — subdomains, not the apex, so look them up there specifically.
