Record generator

DMARC record generator

Choose a policy, set alignment, and point aggregate reports somewhere you will actually read them — then roll it out at a percentage you can undo.

Domain

Only used by “Check current record” below — it is looked up at _dmarc.<domain>.

Policy (p)

Subdomain policy (sp)

Rollout percentage (pct)

Applies the policy above to only this share of failing mail — useful while rolling out.

Aggregate reports to (rua)

Comma-separate multiple addresses. Sent as daily aggregate summaries.

Forensic reports to (ruf)

Optional — few receivers send these, and they can include message details.

SPF alignment (aspf)

DKIM alignment (adkim)

Generated record

Look up the TXT record currently published at _dmarc.<domain> and compare it with the record you just built.
