Adding a DNS record at Amazon Route 53

First make sure Amazon Route 53 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.

1. Open Hosted zones and choose your domain.
2. Click Create record, enter the record name (for DMARC: _dmarc) and choose type TXT or CNAME.
3. For TXT, paste the value in quotes, e.g. "v=DMARC1; ...". Split values longer than 255 characters (such as 2048-bit DKIM keys) into several quoted strings: "part1" "part2".
4. Create the record.

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.
