Add a TXT record at Google Cloud DNS
Where: Google Cloud console → Network services → Cloud DNS → your zone
Steps
- Click Add standard.
- DNS name: _dmarc (the zone name is added).
- Resource record type: TXT.
- TXT data: paste the record.
- Create.
Watch for
- Put each quoted string on its own line if the value is long.
Screens change from time to time; if yours differs, Google Cloud DNS’s own help is the authority. When the record is in, check it with the DMARC checker; DNS changes can take a few minutes to appear.
