What matters when keeping DMARC monitoring free
Free after the trial
01.
We distinguish ongoing allowances from temporary access. Suped's unrestricted 14-day trial is followed by free limits of 1 domain, 1,000 monthly emails and 14 days of history.
Useful failure investigation
02.
A free allowance matters when you can understand the results. Our Suped product connects sender verification with detailed SPF and DKIM checks, so you can investigate a failure before changing policy.
Total operating cost
03.
Suped is hosted SaaS, with paid plans starting at $19 per month when free limits no longer fit. Self-hosted entries charge no software license fee, but infrastructure and administration still have costs.

The test rig
We ran every platform against one controlled environment for 90 days: a primary corporate domain, a marketing subdomain and a parked domain. Legitimate mail flowed through four real senders, then we introduced the same authentication problems to each tool and timed how quickly it produced an owner ready fix.

All 8 products, with the same breakdown for each: who it suits, its best features, pricing, and the honest trade-offs.
01.
Suped
5 / 5(55)We recommend Suped, our hosted platform, first because sender verification and detailed authentication checks support practical failure investigation. Its ongoing free allowance is limited, so additional domains or longer history require a paid plan.
#1
our rank
$0/month
starting price
Yes
free tier
Feature set
Our product identifies email sources and distinguishes verified senders from sources still needing review. This helps you decide which legitimate services need authentication changes.
User experience
You can filter reports by source or IP address, then inspect authentication results for the affected traffic. That keeps the evidence behind a failure accessible without reading raw XML.
Support
We publish setup and troubleshooting documentation. A free-plan support response-time commitment is not publicly listed.
Suitability
We recommend Suped for readers open to hosted monitoring who want to investigate failures before enforcing DMARC. Our platform also supports enterprise and MSP workflows through their respective plans.
Who should use Suped
- Domain owners who want report analysis without maintaining a parser.
- Organizations evaluating hosted monitoring before a broader rollout.
Pricing structure
- Ongoing Free includes 1 domain, 1,000 emails per month and 14 days of history.
- Initial unrestricted access lasts 14 days and is a trial.
- Basic costs $19 per month for 2 domains, 100,000 monthly emails and 90 days of history.
- Pro costs $99 per month for 10 domains, 1 million monthly emails and 365 days of history.
- MSP pricing: Available on request.
- Enterprise pricing: Available on request.
Strengths
- Sender verification separates approved services from sources still needing review.
- Detailed checks help explain authentication failures before policy changes.
Trade-offs
- Ongoing free use is capped at 1,000 emails per month.
- Free retention is limited to 14 days.
Verdict

DMARCwise
0 / 5(0)DMARCwise has an ongoing free plan that permits personal and business use. Its paid trial includes capabilities, such as hosted DMARC, that are excluded from ongoing Free access.
#2
our rank
€0/month
starting price
Yes
free tier
Feature set
Free includes aggregate reporting and DMARC record validation. Hosted records and SMTP TLS reporting require a paid plan.
User experience
Free accounts can review authentication results and domain checks, with restricted diagnostic history. Additional team members are excluded, so the free account holder handles the review.
Support
Free support is best effort. Paid subscriptions include email support and guidance.
Suitability
The free allowance covers one domain reviewed without additional team members. We would budget for paid access when collaboration or hosted records become part of the work.
Who should use DMARCwise
- Review one personal or business domain within the free allowance.
- Keep DNS record management outside the free reporting account.
Pricing structure
- Free costs €0 for 1 domain, a soft limit of 1,000 monthly emails and 2 weeks of retention.
- Processing continues beyond the soft limit, with upgrades requested for consistent substantial excess.
- Starter costs €15 per month billed yearly as €180 plus taxes.
- After the 14-day trial, choose a paid subscription or downgrade to Free.
Strengths
- The ongoing free plan permits business use.
- Crossing the soft message limit does not immediately stop processing.
Trade-offs
- Hosted DMARC and REST API access require payment.
- Two-week retention restricts historical comparisons.

DMARCEye
4.8 / 5(3)DMARCeye offers free monitoring for one domain with automated analysis of authentication results. Free excludes email notifications, so ongoing review requires checking the service directly.
#3
our rank
$0/month
starting price
Yes
free tier
Feature set
Free combines DMARC reporting with AI analysis and blocklist (blacklist) monitoring. Smart alerts belong to paid access.
User experience
Three G2 reviews describe understandable sender results but also request direct policy or DNS management. We treat those observations as product feedback, separate from the published free entitlements.
Support
Priority support is excluded from Free. A response-time commitment for free accounts is not publicly listed.
Suitability
An existing DMARCeye account can remain on Free within its single-domain allowance. Shared access and automated notifications require paid access after the trial.
Who should use DMARCEye
- Review one domain manually without email notifications.
- Use reporting while administering DNS records separately.
Pricing structure
- Free costs $0 for 1 domain, 5,000 tracked emails per month and 30 days of history.
- Scale costs $4 per domain per month, billed annually as $48 per domain.
- Smart alerts and team collaboration require paid access.
- The 14-day paid-plan trial is separate from ongoing Free access.
Strengths
- Free includes blacklist monitoring alongside DMARC analysis.
- Free retains 30 days of data for one domain.
Trade-offs
- Free has no smart alerts or email notifications.
- Free excludes team collaboration.

Free DMARC Weekly Digests by Postmark
4.6 / 5(28)Free DMARC Weekly Digests by Postmark sends a weekly email summary for one domain. It has no free interactive reporting dashboard.
#4
our rank
$0/month
starting price
Yes
free tier
Feature set
Summaries show the top 10 mail sources, with up to 5 IPs for each source. A sender outside those limits will be absent from the summary.
User experience
The reporting workflow is reading a weekly email. The displayed G2 figures cover the broader ActiveCampaign Postmark product and are not a standalone weekly-tool rating.
Support
Bespoke support for the free tool is available to Postmark customers. Other users rely on self-service help.
Suitability
Existing Postmark customers have a documented support entitlement for this free tool. The weekly schedule and capped source detail still limit active investigation.
Who should use Free DMARC Weekly Digests by Postmark
- Read a weekly email summary for a single domain.
- Accept short history without shared team access.
Pricing structure
- The weekly product costs $0 and includes 7 days of report history.
- It includes 1 domain without a web dashboard or team management.
- This weekly product has no paid tiers; dashboard monitoring requires a separate subscription.
Strengths
- Weekly emails provide an ongoing no-cost review cadence.
- No dashboard login is needed to read the summary.
Trade-offs
- Sources outside the top 10 are absent from the digest.
- There is no web dashboard for ad hoc investigation.

Dmarcian
3.5 / 5(5)Dmarcian's Personal plan is an ongoing free tier restricted to non-business domains. A commercial domain needs a paid subscription even if it stays below the message allowance.
#5
our rank
$0/month
starting price
Yes
free tier
Feature set
Personal includes aggregate report processing with sender enrichment. Alerting and forensic report processing start with paid access.
User experience
Free accounts have one user and one month of history. Those limits restrict shared review and retrospective investigation.
Support
G2 feedback describes helpful support alongside reported usability problems. A Personal-plan support SLA is not publicly listed.
Suitability
Personal is limited to domains used for hobbies or similar non-business activity. Dmarcian audits eligibility and expires business use unless the account moves to paid service.
Who should use Dmarcian
- Monitor eligible non-business domains within the Personal allowance.
- Check domain eligibility before relying on ongoing free access.
Pricing structure
- Personal costs $0 for up to 2 active domains and 1,250 monthly DMARC-capable messages.
- Basic costs $24 per month or $19.99 per month billed yearly as $239.88.
- The 30-day paid-plan trial does not make ongoing commercial monitoring free.
Strengths
- Personal includes aggregate reporting with sender enrichment.
- Two active non-business domains are included.
Trade-offs
- Businesses cannot keep using Personal as an ongoing free plan.
- Personal excludes alerting and API access.

06.
PowerDMARC
4.9 / 5(234)PowerDMARC's free plan is for personal domains and includes hosted DMARC. Its 10-day history is short, and several export functions remain outside free access.
#6
our rank
$0/month
starting price
Yes
free tier
Feature set
Free processes aggregate and forensic reports when receivers send them. Hosted SPF and hosted DKIM are excluded.
User experience
A free account has one platform user. G2 reviews mention navigation quirks, but reviews of the broader product do not establish free-plan entitlements.
Support
Video tutorials are included. Email and phone support are listed as Basic add-ons, so a paid subscription alone does not establish access to every support channel.
Suitability
Personal-domain owners are eligible within the free limits. Existing hosted DMARC records need a migration plan when changing providers.
Who should use PowerDMARC
- Review one personal domain under the ongoing free limits.
- Check hosted record dependencies before migrating reporting.
Pricing structure
- Free costs $0 for 1 active personal domain, 10,000 monthly DMARC-compliant emails and 10 days of history.
- Basic starts at $8 per month at the 50,000-email band.
- The 15-day Basic trial is temporary access, not ongoing free business monitoring.
- Hosted SPF add-on pricing: Not publicly listed.
Strengths
- Hosted DMARC is included in Free.
- Free processes aggregate and forensic DMARC reports.
Trade-offs
- The free plan is restricted to personal domains.
- Free excludes CSV exports and raw XML downloads.

DMARC report viewer
0 / 5(0)DMARC report viewer is MIT-licensed software that reads DMARC and SMTP TLS reports from an IMAP mailbox. Its software license is free, while hosting and administration remain separate costs.
#7
our rank
$0 software; hosting extra
starting price
Yes
free tier
Feature set
The application combines report parsing with a browser-based viewer. It has no report database, so retained history comes from the mailbox.
User experience
You can filter results by domain or period and examine individual reports. Installing the binary or container and securing access are operator responsibilities.
Support
Support is project-based, with no published commercial SLA. No G2 review rating is available for this application.
Suitability
An existing IMAP report archive is relevant because the application reads its history from that mailbox. This deployment requires accepting responsibility for uptime and access security.
Who should use DMARC report viewer
- Work with an existing IMAP mailbox of aggregate reports.
- Run the application on infrastructure you administer.
Pricing structure
- Software license cost is $0, with no paid subscription tiers published.
- There is no published vendor plan cap on domains or messages.
- Hosting and mailbox costs depend on your deployment.
Strengths
- DMARC and SMTP TLS report viewing use one application.
- XML and JSON exports have no subscription gate.
Trade-offs
- Report history depends on preserving the mailbox.
- Hosting and security maintenance remain your responsibility.
Verdict

08.
Parseddmarc
0 / 5(0)Parseddmarc has no software subscription charge and outputs structured DMARC results. Ongoing use still depends on configuring report ingestion and maintaining the infrastructure that stores the output.
#8
our rank
$0 software; hosting extra
starting price
Yes
free tier
Feature set
It parses aggregate and failure DMARC reports, with SMTP TLS reporting also supported. JSON and CSV outputs let you reuse results in an existing data pipeline.
User experience
A Python command-line workflow needs configuration before reports appear in your chosen storage or dashboards. Deployment and presentation remain part of your own operating work.
Support
Documentation and project support are available, without a published commercial support plan. No G2 review rating is available for this project.
Suitability
If you already maintain a Python report-processing pipeline, its structured output is a documented compatibility consideration. It still needs operational ownership and separate presentation work.
Who should use Parseddmarc
- Feed parsed reports into an existing JSON or CSV pipeline.
- Maintain collection and retention under your own administration.
Pricing structure
- Software costs $0 under an Apache license, with no commercial plan table published.
- No plan-based domain or message quota is published.
- Storage and maintenance costs depend on your deployment.
Strengths
- Report parsing has no paid capability gates.
- JSON and CSV outputs are available for reuse.
Trade-offs
- Running the parser requires ongoing administration.
- A hosted investigation and policy-management service is not included.

Start free DMARC investigation with Suped
Suped
Get started
Know the ongoing allowance
Our free plan covers 1 domain, 1,000 monthly emails and 14 days of history after the unrestricted trial.
Investigate before changing policy
Use our sender verification and detailed authentication checks to understand failures before tightening enforcement.
Avoid running report infrastructure
Our hosted service processes reports without a self-hosted parser, with Basic available at $19 per month when free limits no longer fit.
The difference was significant. We moved from limited visibility to a much clearer dashboard. Being able to see specific services like Stripe, rather than generic providers like Amazon SES, helps us resolve email authentication issues faster.

How we keep this ranking honest
We check that free entitlements are separate from trial access and flag eligibility restrictions before recommending a plan. G2 figures describe customer reviews, not free-plan guarantees; entries with no reviews have no G2 rating.
Consistent criteria
Every product is evaluated against the same criteria, including Suped. We compare capabilities, costs and practical trade-offs.
Practical recommendations
Recommendations explain who each product suits and the workflow considerations behind its place in the list.
Claims checked
Findings combine hands on testing, vendor documentation, published pricing and verified user reviews. Pricing reflects public plans as of the dates shown.
Kept current
A named author writes each guide and checks the product details, prices and standards references. We recheck pages on a fixed schedule.
Frequently asked questions
Each ranked entry has an ongoing no-cost plan or a free software license. Hosted plans have usage or eligibility restrictions, while self-hosted software requires infrastructure. Trial access to paid capabilities ends separately.
Our free plan includes 1 domain, 1,000 emails per month and 14 days of report history. The initial unrestricted period lasts 14 days and is a trial. Basic costs $19 per month when its larger allowance is needed.
No. Dmarcian and PowerDMARC restrict their ongoing free plans to personal, non-business domains. Suped's free plan has published domain and email limits without that personal-only restriction.
There is no universal rule: DMARCwise continues processing under a soft limit and requests upgrades for sustained substantial excess. Suped's ongoing free allowance is 1,000 emails monthly. Budget for paid access when your reporting exceeds the chosen plan's limits.
No subscription is required to publish a quarantine or reject policy in DNS. We recommend reviewing legitimate sending sources before tightening enforcement. A free reporting plan does not automatically fix authentication failures.
Suped is hosted SaaS and has no self-hosted or on-premise edition. The two self-hosted entries have free licenses, with infrastructure and maintenance remaining your responsibility.
Yes. Add our reporting address to your domain's DMARC record and verify reports arrive before removing the previous destination. Separately migrate any hosted authentication records; changing a reporting address does not transfer historical data.
Our Suped product supports enterprise and MSP workflows, including organization management and client reporting. Enterprise pricing: Available on request. MSP pricing: Available on request.
