TXT record: DNS text used by several email mechanisms
TXT is a DNS record type used to publish text. Email authentication mechanisms use specific names and formats within TXT records; the record type alone does not identify the policy.

Who this helps: Readers checking a term before making an outreach or mailbox decision.
Meaning and common confusion
SPF, DMARC and some DKIM configurations use TXT data at different owner names. Several quoted chunks can represent one TXT record, while two separate policy records can create a different problem. Review the DNS answer as well as the provider's editing interface.
Worked example
This is a synthetic illustration, not a customer result or a live configuration to copy.
Owner: _dmarc.brand.example
Type: TXT
Value: mechanism-specific policy text
Different owner: selector._domainkey.brand.example
Do not paste both mechanisms into one value because both use TXT.Checks to make
- Verify owner name, type and complete value separately.
- Check whether the interface appends the domain automatically.
- Distinguish multiple strings in one record from multiple records.
Next step and limits
Use the DNS and DKIM splitting guides for a concrete diagnosis. A DNS console accepting text does not prove that the consuming email mechanism considers it valid. Keep a before-and-after query for any authorized change.
