Adding a DNS record at Porkbun
First make sure Porkbun actually serves your DNS: records only work where your domain's nameservers point. If your domain is registered here but uses another company's nameservers, add the records there instead.
- Open Domain Management and click DNS next to your domain.
- Choose type TXT or CNAME, enter the host (for DMARC: _dmarc) and paste the answer.
- Click Add.
Only one DMARC record may exist per domain. If _dmarc already has one, edit it instead of adding a second.
Changes usually appear within an hour, longer if an old record had a long TTL. Then check your domain.
Steps are typical; menus change. If something doesn't match, check Porkbun's own help pages.
