About TXT records

TXT records hold text for other systems to read. Email security relies on them heavily: SPF lives in a TXT record on the domain, DMARC at _dmarc, DKIM keys at selector._domainkey, and MTA-STS and TLS-RPT at their own names.

Services such as Google, Microsoft and Stripe also ask you to publish TXT records to prove you own a domain. Long values are split into 255-character chunks, which are joined when read.

Frequently asked questions

Is it OK to have many TXT records?

Yes, as long as there is only one SPF record (v=spf1) on the domain and one DMARC record at _dmarc.
