What TXT records are used for

A TXT record stores arbitrary text against a domain name. It started as a free-form comment field and became the place the internet puts machine-readable policy.

The common uses you'll see in results:

  • SPF — begins v=spf1, lists who may send mail as your domain.
  • DKIM — begins v=DKIM1, published on a selector subdomain, holds a public signing key.
  • DMARC — begins v=DMARC1, published at _dmarc.yourdomain.
  • Domain verification — strings from Google, Microsoft, Atlassian and others proving you control the domain.

Common TXT record problems

Two SPF records. A domain may publish only one record starting v=spf1. Two is a permanent error and mail providers may reject your mail. Merge them into a single record.

The 255-character limit. A single TXT string cannot exceed 255 characters. Longer values must be split into multiple quoted strings, which resolvers concatenate. DKIM keys almost always need this.

Too many DNS lookups in SPF. SPF permits a maximum of ten DNS-resolving mechanisms. Chained include: statements blow past this quietly and cause a permerror.
