A DMARC record is the record where the DMARC rulesets are defined. This record informs the ISPs (like Gmail, Microsoft, Yahoo! etc.) if a domain is set up to use DMARC. The DMARC record contains the policy.
The DMARC record should be placed in your DNS. The TXT record name should be “_dmarc.yourdomain.com.” where “yourdomain.com” is replaced with your actual domain name (or subdomain).
