What is a TXT record used for?

TXT records store arbitrary text data in DNS. Common uses include SPF (sender policy), DKIM (email signing keys), DMARC (email policy), domain ownership verification for Google/Microsoft, and BIMI (brand logo in email).

How do I add an SPF record as a TXT record?

Add a TXT record to your domain's DNS with the value like "v=spf1 include:_spf.google.com ~all". Replace the include with your mail provider's SPF hostname. Only one SPF record is allowed per domain.

Can a domain have multiple TXT records?

Yes, a domain can have multiple TXT records, but only one SPF record (v=spf1). Multiple TXT records for DKIM selectors, DMARC, and domain verification are all valid simultaneously.

TXT Records

TXT records allow administrators to add arbitrary text to a domain's DNS configuration. They are commonly used for email verification and SPF (Sender Policy Framework).

Common Uses for TXT Records

SPF (Sender Policy Framework)

v=spf1 include:_spf.google.com ~all

SPF records specify which mail servers are authorized to send email on behalf of your domain. This helps prevent email spoofing.

DKIM (DomainKeys Identified Mail)

v=DKIM1; k=rsa; p=MIGfMA0GCSqGS...

DKIM adds a cryptographic signature to emails to verify they weren't modified in transit.

DMARC

v=DMARC1; p=quarantine; rua=mailto:[email protected]

DMARC builds on SPF and DKIM to provide email authentication policy and reporting.

Domain Verification

Many services (Google, Microsoft, etc.) use TXT records to verify domain ownership.

Best Practices

Keep SPF records simple — include only necessary servers
Don't exceed 255 characters per string; use semicolons to add more
Monitor DMARC reports to catch issues
Test TXT records with our TXT Lookup tool
