Free DMARC monitoring: your options compared

Free DMARC monitoring options compared

Limits as of September 2026, from each provider’s own site. “Not published” means we couldn’t find the limit stated officially.

Cloudflare DMARC Management

If your domain’s DNS is on Cloudflare, DMARC Management is included on every Cloudflare plan at no extra cost. It collects your aggregate reports, shows email volume and pass/fail rates for SPF, DKIM and DMARC, lists your top sending sources and lets you drill into each one. The dashboard lets you view a period of up to 30 days. It isn’t available for domains whose DNS is hosted elsewhere, and Cloudflare doesn’t publish a longer retention period.

Postmark’s free DMARC digest

Postmark’s DMARC service still offers a free weekly digest, sent every Monday, as of September 2026. You add Postmark’s report address to your record and it emails you a summary of your top 10 mail sources (five IPs each), keeping seven days of data. There’s no web dashboard on the free tier. The paid version is $14 a month per domain and adds all sources, 60 days of history and a dashboard.

Free plans from DMARC vendors

• PowerDMARC Free covers one active domain and up to 10,000 DMARC-compliant emails a month with 10 days of history. Unusually for a free plan, it processes forensic (RUF) reports as well as aggregate ones and hosts DMARC and BIMI. Paid plans start at $8 a month.
• dmarcian Personal is free for non-business domains (dmarcian says it audits these to keep them non-commercial): two domains, 1,250 DMARC-capable messages a month and one month of history. Its paid Basic plan is $24 a month, or $19.99 a month billed annually, and every paid plan has a 30-day trial.
• Valimail Monitor is free with no trial period or credit card. It names the services sending as your domain, shows where they pass and fail, and sends a weekly DMARC report. Valimail doesn’t publish domain, volume or history limits for Monitor. Its pricing page lists Monitor with up to five users, limited DMARC automation and SPF limited to 10 lookups; full automation and automated DKIM are in its paid Enforce plans.
• EasyDMARC lists paid plans on its business pricing page as of September 2026, starting with DMARC Plus at $35.99 a month billed annually (two domains, 100,000 emails a month, three months of history), plus a free trial. We couldn’t find a free plan on that page.
• URIports doesn’t have a free plan but offers a one-month free trial. Its Pebble plan is $6 a month billed annually ($7 monthly) for five domains and 100,000 reports a month with 30 days of retention, and its Sand plan for personal and hobby projects is $15 a year for three domains and 10,000 reports a month. All its plans include unlimited email volume.

DMARC Dojo Free

DMARC Dojo’s Free plan covers one domain with no email-volume limit. It hosts your DMARC, SPF and DKIM records (your _dmarc record becomes a CNAME, so later policy changes need no DNS edits), gives the domain a private report inbox, and parses every aggregate report into daily pass/fail stats and per-source results with provider identification. You get dashboards and email digests that list the next action until the domain reaches p=reject. It doesn’t process forensic reports or host BIMI or MTA-STS, and it’s a new service (launched 2026). More domains need Pro ($19 a month for 25).

DIY: parsedmarc and a mailbox

parsedmarc is a free, open-source Python tool that parses aggregate, failure and SMTP TLS reports. It pulls reports from a mailbox over IMAP, Microsoft Graph or the Gmail API and sends the results to Elasticsearch, OpenSearch, Splunk or PostgreSQL for use with premade dashboards, or to Kafka and other outputs. You keep as much history as you want to store.

The cost is effort. You run a mailbox for reports, a server for parsedmarc, and a search cluster sized for your report volume, and you keep all of it patched. It’s a good fit if you already operate that stack. You also still edit DNS by hand.

The simplest option of all is a mailbox you own. Point rua at it and open a report when you need to:

v=DMARC1; p=none; rua=mailto:dmarc-reports@example.com

Reports arrive as zipped or gzipped XML. Drop one into the DMARC report analyzer, which reads it in your browser, or see how to read aggregate reports. This works for occasional checks, but a busy domain gets many reports a day and nobody reads them by hand for long.

How to choose

• DNS on Cloudflare? Turn on DMARC Management first. It costs nothing and needs no extra account.
• Just want a weekly heads-up? Postmark’s digest or Valimail Monitor’s weekly report is enough to spot a new sender.
• A personal or hobby domain? dmarcian Personal fits well within its non-business terms.
• Need forensic reports or hosted BIMI for free? PowerDMARC Free, as long as you stay under 10,000 emails a month.
• One business domain with real volume, heading to enforcement? DMARC Dojo Free has no volume cap and hosts DMARC, SPF and DKIM so you can tighten policy without touching DNS.
• Already run a search stack? parsedmarc gives you full control and unlimited history.

When free isn’t enough

You’ve likely outgrown a free tool when:

• You have more domains than the plan allows, or your volume passes its cap and reports stop being processed.
• You need more than a week or a month of history to spot trends or satisfy an audit.
• You manage domains for clients and need separate accounts, roles or client-facing reports.
• You need SSO, a security certification from the vendor, or phone support.
• You’re ready to move from p=none to reject and want help deciding when it’s safe (see moving from p=none to p=reject).

Paid options range widely, from a few dollars a month to enterprise quotes. Our comparisons with dmarcian, EasyDMARC, PowerDMARC, Valimail and Red Sift OnDMARC cover what each costs.
