Create a DMARC TXT record with an explicit policy, optional reporting address and alignment settings.
Choose a policy and copy the resulting TXT record to _dmarc.your-domain. Monitoring is a sensible starting point while you inventory legitimate senders.
none requests monitoring; quarantine and reject ask receivers to act on DMARC failure. Moving to enforcement should follow evidence about legitimate traffic.
Use an inbox or report-processing service prepared to receive aggregate reports. External destinations may need authorization in their DNS.
The generator does not promise a delivery improvement or generate a synthetic health score. Correct setup is only part of successful email delivery.
The generator allows it to be omitted. Without a reporting destination you lose a key source of operational feedback.
Strict alignment requires exact domain matches for the relevant authenticated identifier. Relaxed alignment allows alignment based on the organizational domain.
