DMARC Record Generator
Build a correct DMARC DNS record for your domain in seconds: choose a policy from monitoring to full reject, set the subdomain policy and rollout percentage, add report emails, then copy the finished TXT record straight into your DNS.
The record hostname will be:
_dmarc.example.com (TXT type).What % of mail the policy applies to — start with 25 for rollout.
Copied to clipboard.
How to use
- Type your domain and select a policy (first time choose none, then enforce after checking reports).
- Enter the report emails so you receive the aggregate reports.
- Click Generate, copy the record, and create a TXT record at the
_dmarchost in your DNS provider.
Good to know
- Start with policy none so you receive reports before any mail is quarantined or rejected.
- The record is published as a TXT entry at the host
_dmarcfollowed by your domain. - Aggregate (rua) reports show who is sending mail as your domain; forensic (ruf) reports show failure details.
- DMARC only works properly when SPF and DKIM are already set up for your domain.
