DMARC Generator

Build a DMARC policy

What is it?

A guided builder for a DMARC TXT record — policy, reporting address, and rollout percentage.

Why it matters

DMARC is meant to be adopted gradually (monitor first, then enforce); the generator produces a syntactically correct record for wherever you are in that rollout.

Impact if ignored

Same stakes as the DMARC Checker above.

Common use cases

Starting DMARC monitoring on a new domain
Moving from a monitoring-only policy toward enforcement at a controlled percentage

Policy

Start with "none" to only monitor, then move to "quarantine" then "reject" once you've confirmed legitimate mail passes.

Report email address (rua)

Percentage of mail this policy applies to

v=DMARC1; p=none; pct=100

Want this monitored continuously?

ESPM tracks your DMARC, SPF, and DKIM posture across every domain you own and alerts you the moment something changes — free demo mode, no credit card required.
