A TXT record is a type of Domain Name System (DNS) record that's stored by your domain provider. With G Suite, you create TXT records to:
- Verify domain ownership, which is required to activate G Suite for your domain.
- Create an SPF record that identifies the authorized mail servers for your domain.
- Add a DomainKey Identified Mail (DKIM) digital "signature" to the header of mail messages sent from your domain.
Most domain providers let you create a TXT record through your domain administration console, similar to the way you create other DNS records such as MX records and CNAME records. However, some providers give only limited support for TXT records or create them differently from other DNS records.
- LiveDns — The domain provider changes all TXT record values to lower case, which invalidates the DKIM domain key
