OnDMARC vs.
DMARC-SRG in 2026
OnDMARC
DMARC-SRG
vs.
We tested OnDMARC and DMARC-SRG for 90 days across a corporate domain, a marketing subdomain, and a parked domain, using Microsoft 365, Google Workspace, SendGrid, Mailchimp, and a support desk sender. OnDMARC was the stronger managed enforcement product, while DMARC-SRG was useful only when we wanted a free, self-hosted parser and accepted manual operations.

Pick OnDMARC for managed enforcement, DMARC-SRG for self-hosted reporting
Pick OnDMARC if
Best for teams that want managed DMARC progress without building tooling
We added the three test domains quickly, then used OnDMARC's policy guidance to separate the corporate domain, marketing subdomain, and parked domain paths.
Microsoft 365 and Google Workspace were labeled cleanly, and the SendGrid and Mailchimp findings pointed us toward the exact SPF and DKIM alignment fixes.
The forwarded mail SPF failure was explained in context, which kept us from treating normal forwarding as spoofing during enforcement planning.
From $9 / month
Pick DMARC-SRG if
Best for technical teams that want a free parser and can operate it themselves
We could ingest aggregate reports and inspect SPF and DKIM results without paying for a SaaS subscription.
The unknown sender required manual classification, which worked for a small test set but would add operator time at higher volume.
The parked domain was easy to monitor once reports arrived, but policy movement and alert routing were handled outside the tool.

Consider Suped if
A third option when guided fixes, hosted records, and simpler ownership matter
Use guided fixes as a buying criterion when the team needs sender-specific next steps instead of raw pass or fail rows.
Prioritize automated issue detection and alert quality when forwarded mail, spoof samples, and new senders need fast triage.
For MSP workflows, check account separation, recurring client reports, and published starter pricing before committing.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric based on the 90-day test. Higher is better in every row, and unsupported capabilities score 0.0.
OnDMARC scores highest where enforcement and managed DNS matter, while DMARC-SRG scores where free self-hosting matters.
OnDMARC moved our corporate domain and marketing subdomain toward a defensible enforcement plan because it connected source names, authentication failures, and DNS fixes in one workflow. DMARC-SRG gave us raw report visibility, but sender classification, alerting, DNS monitoring, and enforcement planning stayed manual. Its best score came from pricing transparency because the software license cost is clear at $0, even though operating costs depend on hosting and administrator time.

Feature set
Managed depth vs parser utility
OnDMARC has the fuller DMARC operating stack. DMARC-SRG has the cleaner self-hosted baseline.
OnDMARC won this category because it connected report analysis, SPF flattening, hosted records, alerts, and enforcement planning. DMARC-SRG worked as a report viewer, but the unknown sender and forwarded SPF failure both needed manual interpretation. A fair buying test should check whether guided fixes and automated issue detection reduce enough operator work to justify a managed platform.
OnDMARC
Microsoft 365 labeled cleanly
SendGrid alignment fix surfaced
Mismatch case explained
DMARC-SRG
Raw reports parsed correctly
Manual sender labels required
Subdomain DKIM needed review
OnDMARC identified Microsoft 365 and Google Workspace as approved core senders quickly, then separated SendGrid and Mailchimp traffic by alignment state so we could fix the marketing subdomain without slowing the corporate domain. In the controlled SPF pass with visible from mismatch case, it showed why the message was still not aligned, and the unauthorized spoof sample was grouped as a policy risk rather than another generic failure row.
DMARC-SRG parsed the same report files and let us inspect DKIM and SPF results by domain, month, and reporter, which was useful for validating the raw evidence. It did not turn SendGrid, Mailchimp, or the support desk sender into owner-ready actions without our notes, and the DKIM pass on a subdomain needed manual explanation before a non-specialist could understand the policy impact.
User experience
Control vs workload
OnDMARC felt like a managed workflow. DMARC-SRG felt like a report workbench.
OnDMARC gave us more screens, but most of them were tied to a next action: validate DNS, classify a source, or review enforcement readiness. DMARC-SRG had fewer moving parts in the UI, but the real workload moved to setup, hosting, sender notes, and explaining results to other teams.
OnDMARC
Three domains added quickly
Unknown sender easier
Forwarding context visible
DMARC-SRG
Lean report screens
Hosting setup required
Manual explanation needed
OnDMARC onboarding for the three test domains was direct: add the domain, publish the generated DNS records, wait for reports, then review sending sources. The unknown sender was easier to investigate because the UI kept domain, reporter, source IP, SPF, DKIM, and alignment context together, and the forwarded SPF failure was presented as an authentication edge case instead of a simple pass or fail decision.
DMARC-SRG took more setup work because we had to configure the web UI, database, report ingestion, and retention ourselves. Once running, it was readable for technical review, but finding the unknown sender meant moving between report rows, IP evidence, and our own notes, and explaining forwarded mail required a separate write-up for stakeholders.
Support
Vendor help vs community operation
OnDMARC fits teams that expect support handoff. DMARC-SRG fits teams that can support themselves.
OnDMARC had a clearer support model for DNS setup, escalation, and enterprise onboarding expectations. DMARC-SRG had no commercial SLA in the materials we reviewed, so support depends on internal administrators and community-style project help.
OnDMARC
DNS handoff was clearer
Escalation path available
Enterprise onboarding stronger
DMARC-SRG
No paid SLA found
Admin owned setup
Community support model
With OnDMARC, the support handoff made the DNS work safer because the generated records, Dynamic SPF decisions, and MTA-STS steps could be reviewed before we changed production records. Escalation expectations were also easier to define for enterprise use, especially when the parked domain spoof sample and marketing subdomain alignment issue needed different levels of urgency.
With DMARC-SRG, support was an operating responsibility rather than a vendor process. We handled database setup, ingestion failures, mailbox access, report cleanup, and DNS interpretation ourselves, which was acceptable in a lab but a weaker fit for a team that needs an onboarding plan, named escalation path, or executive-ready enforcement notes.
Suitability
Enterprise fit vs operator fit
OnDMARC suits managed security programs. DMARC-SRG suits technical owners with narrow reporting needs.
OnDMARC was the better fit for enterprise teams that need policy movement, DNS ownership, and support handoff across domains. DMARC-SRG fit the buyer who wants full control of a free self-hosted parser and accepts manual client reporting. For MSPs and lean operators, account separation, recurring reports, and alert quality should be tested early because those gaps change weekly workload.
OnDMARC
Enterprise domain grouping works
Policy paths stay separate
Department mapping needs care
DMARC-SRG
Best for one operator
No client grouping
Reports need packaging
OnDMARC handled our corporate domain, marketing subdomain, and parked domain as separate work items, which helped enterprise review because each domain had a different policy path. Account separation was usable, but large domain groups still required care when mapping departments, owners, and recurring status notes, which matches the kind of effort reviewers often mention for larger estates.
DMARC-SRG was simplest for a single technical owner or SMB that wants report access without SaaS cost. It did not have built-in multi-tenant client grouping, recurring client reports, or structured handoff notes, so an MSP would need external process around every client, especially when unknown senders or spoof samples need non-technical explanation.
What each tool feels like after 90 days of real use
OnDMARC
A managed DMARC product for teams moving toward enforcement
After 90 days, OnDMARC felt strongest when we treated DMARC as an operating program rather than a reporting task. The corporate domain moved through source review and policy planning cleanly, while the marketing subdomain stayed separate enough that SendGrid and Mailchimp fixes did not confuse Microsoft 365 or Google Workspace decisions.
The product produced more information than a casual user needs, but most of it had a purpose. We could explain the forwarded SPF failure, isolate the unauthorized spoof sample on the parked domain, and hand a DNS owner concrete changes instead of asking them to interpret raw aggregate rows.

DMARC-SRG
A free parser for teams that can own every operational step
After 90 days, DMARC-SRG felt useful for proving what the reports said and limited for deciding what to do next. We could inspect the corporate domain, marketing subdomain, and parked domain reports, but source ownership, policy movement, and alert thresholds lived in our own notes.
The free software cost was real, but the operational cost was also real. The unknown sender, forwarded mail SPF failure, and DKIM pass on a subdomain all required manual explanation before another team could act on them.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Guided fixes without dense triage
OnDMARC surfaced rich data, but new users still had to learn which dashboards mattered. Suped turns sender issues into specific fixes so Microsoft 365, Google Workspace, SendGrid, Mailchimp, and support desk traffic can be handled by owner.
Managed operations without self-hosting
DMARC-SRG parsed reports, but we had to run the database, ingestion, retention, and monitoring. Suped removes that operational work while keeping the workflow focused on DMARC policy progress.
Cleaner MSP and alert workflows
DMARC-SRG lacked built-in client separation, and OnDMARC domain grouping still needed careful owner mapping at scale. Suped's product supports account separation, recurring reporting, and alerts designed for client handoff.
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.
