TXT Record Lookup

About TXT Record Lookups

TXT (text) records are a flexible DNS record type that allows domain owners to associate arbitrary text with a domain. Originally intended for human-readable information, TXT records are now essential for email authentication, domain ownership verification, and security policy publication.

Common TXT record uses

• SPF (Sender Policy Framework) — Specifies which mail servers are authorised to send email for the domain. Starts with v=spf1. Used by receiving servers to detect spoofed senders.
• DMARC — Published at _dmarc.example.com, defines the policy for handling emails that fail SPF or DKIM checks. Starts with v=DMARC1.
• DKIM — DKIM public keys are published at {selector}._domainkey.example.com. Used to verify email signatures.
• Domain verification tokens — Services like Google Search Console, HubSpot, Mailchimp, and many others ask you to add a TXT record to prove you own a domain before granting access.
• MTA-STS and BIMI — Newer email standards also use TXT records to publish policy pointers.

Multiple TXT records

A domain can have multiple TXT records at the same name. However, SPF must have exactly one record — multiple SPF TXT records at the same name cause a permanent error (permerror) that may result in email being rejected. If you need to cover multiple sending sources, combine them into a single SPF record.
