TXT Record Lookup
Check TXT records (SPF, DKIM, DMARC, domain verification) for any domain across 12 global resolvers. Free DNS checker.
What is a TXT record?
A TXT record holds free-form text. In practice, it's the workhorse for several critical use cases: SPF (sender-policy framework), DKIM (signing keys for outgoing email), DMARC (email-auth policy), and domain verification (Google Search Console, Microsoft 365, Apple Business, etc.).
When to check TXT records
- You added an SPF/DKIM/DMARC record and need to confirm it's live before mail starts flowing
- A domain-verification step in some service is failing — confirm the TXT was actually published
- You suspect an unauthorized SPF or DMARC change
- You want to inspect another domain's mail-auth posture
FAQ
What does an SPF record look like?
SPF is a TXT record that starts with v=spf1 followed by mechanisms like include:_spf.google.com and ends with a policy like ~all or -all. Example: v=spf1 include:_spf.google.com ~all.
Where do DKIM records live?
DKIM records are TXT records at <selector>._domainkey.example.com. Each mail provider has its own selector (e.g., google._domainkey, k1._domainkey).
Where does DMARC live?
DMARC is a TXT record at _dmarc.example.com. Look up that exact subdomain to see the DMARC policy.
