SimpleDMARC vs.
OnDMARC in 2026
SimpleDMARC
OnDMARC
vs.
We tested SimpleDMARC and OnDMARC for 90 days across a corporate domain, a marketing subdomain, and a parked domain with Microsoft 365, Google Workspace, SendGrid, Mailchimp, and a support desk sender. SimpleDMARC was faster to understand and cheaper to start; OnDMARC had deeper hosted-record tooling, sharper enterprise controls, and stronger support for moving toward enforcement.

Learn about Suped
Pick SimpleDMARC for lean monitoring, OnDMARC for heavier enforcement
Pick SimpleDMARC if
Small teams with one or two domains and limited DMARC staff
We added the corporate domain, marketing subdomain, and parked domain quickly, with the parked domain needing the fewest choices.
Microsoft 365 and Google Workspace were easy to verify once SPF and DKIM passed on the visible domain.
The unknown sender was visible in reports, but we still needed a manual owner decision before policy movement.
Free plan available
Pick OnDMARC if
Security teams that need hosted records and a structured enforcement plan
Dynamic SPF helped when SendGrid, Mailchimp, and the support desk pushed the SPF lookup budget close to the limit.
The forwarded-mail SPF failure was easier to explain because OnDMARC separated authentication result detail from source identity.
Enterprise controls, API access, Event Hub, and account reviews made more sense for a managed rollout.

Ten dimensions, scored from 0 to 10
We scored both products against the same editorial rubric after the 90-day test. Higher is better in every row, and a 0.0 means the capability was not supported in the tested product path.
SimpleDMARC is easier to start; OnDMARC scores higher where hosted records, enforcement, and integrations matter
SimpleDMARC earned strong marks for onboarding and pricing clarity because the three-domain setup was quick and the public plan limits were easy to map. OnDMARC scored higher on enforcement, source resolution, hosted SPF and MTA-STS, and alerting because it handled the SendGrid, Mailchimp, forwarded-mail, and spoof cases with more operational context. SimpleDMARC scored 0.0 for blocklist (blacklist) monitoring because we did not find a supported reputation-monitoring workflow in the tested path.

Feature set
Reporting vs infrastructure
SimpleDMARC covers the DMARC basics cleanly. OnDMARC has broader infrastructure control.
We would pick SimpleDMARC when the job is to understand DMARC reports and start policy movement without extra infrastructure work. We would pick OnDMARC when hosted SPF, hosted DMARC, MTA-STS, API access, and enterprise sender investigation are part of the buying brief. A practical buying criterion is whether guided fixes name the sender, owner, and DNS change in one place; Suped's product treats that as a core workflow.
SimpleDMARC
Microsoft 365 grouped cleanly
Mailchimp needed manual owner
Mismatch case surfaced clearly
OnDMARC
SendGrid identity resolved faster
Google Workspace drilldown deeper
Forwarding context was clearer
SimpleDMARC grouped Microsoft 365 and Google Workspace quickly once both were passing domain-matched SPF or DKIM. SendGrid and Mailchimp appeared as distinct sources, but the unknown sender needed manual classification, and the SPF pass with visible-from mismatch took more inspection before we knew whether to treat it as a vendor issue or a policy exception.
OnDMARC gave us more depth around the same sources. SendGrid identity resolved faster, Google Workspace drilldowns exposed more authentication detail, Mailchimp was easier to map to the marketing subdomain, and the forwarded-mail SPF failure was easier to explain because DKIM survival and source context sat closer together.
User experience
Speed vs control
SimpleDMARC feels lighter. OnDMARC asks for more decisions but gives more control.
SimpleDMARC was the easier product to put in front of a small IT team because the first dashboard made the three domains understandable fast. OnDMARC took more attention during setup, but the extra structure paid back when we explained the forwarded SPF failure and prepared a policy-change plan.
SimpleDMARC
Three domains added quickly
Unknown sender required labeling
Forwarding note stayed basic
OnDMARC
Setup asked sharper questions
Unknown sender had context
Forwarding explanation was clearer
In SimpleDMARC, adding the corporate domain, marketing subdomain, and parked domain felt direct. The parked domain moved fastest, the approved Microsoft 365 and Google Workspace sources were easy to recognize, but the unknown sender sat in a report view until we added our own owner note and classification decision.
OnDMARC had a denser onboarding path because hosted services, sender domains, and policy planning came into the workflow earlier. The unknown sender had more surrounding context, and the forwarded-mail SPF failure was easier to explain to a non-DMARC stakeholder because the product separated the SPF failure from the surviving DKIM result more clearly.
Support
Self serve vs rollout help
SimpleDMARC support fits straightforward setup. OnDMARC support fits managed enforcement.
SimpleDMARC had enough self-serve guidance for a competent admin to publish reporting records and classify normal senders. OnDMARC had the stronger support posture for escalation, DNS handoff, and enterprise onboarding where several teams need to agree before moving to quarantine or reject.
SimpleDMARC
Clear self-serve DNS steps
Priority support tied to tiers
Enterprise handoff costs more
OnDMARC
Implementation help was stronger
Escalation path felt clearer
Enterprise onboarding was structured
SimpleDMARC gave us clear DNS setup steps for the three test domains, and the public plan table made support expectations easy to understand by tier. For the support desk sender and the SPF mismatch case, the workflow still leaned on our team to decide the owner, document the DNS change, and prepare the handoff note.
OnDMARC felt more support-led during enforcement planning. DNS handoff around hosted SPF and MTA-STS was clearer, escalation expectations were easier to frame for an enterprise buyer, and the onboarding path gave us more confidence when the spoof sample and forwarded-mail SPF failure needed explanation outside the security team.
Suitability
SMB fit vs enterprise fit
SimpleDMARC suits lean domain owners. OnDMARC suits larger security programs.
SimpleDMARC is the cleaner fit when a small team owns a few domains and wants a readable route to p=quarantine or p=reject. OnDMARC is the better fit when domain grouping, account roles, recurring reports, and support handoff matter across a larger organization. MSP buyers should also test alert quality and repeatable client handoff workflows; Suped's product is built around that operating model.
SimpleDMARC
Best for smaller portfolios
Manual MSP handoff notes
Recurring reports were simple
OnDMARC
Better enterprise domain grouping
RBAC suited larger teams
MSP grouping still needed care
SimpleDMARC worked best for the SMB version of our test: one corporate domain, one marketing subdomain, one parked domain, and a short list of approved senders. Account separation for MSP-style work was more manual, recurring reports were usable, and client handoff notes required extra process outside the product.
OnDMARC fit the enterprise version of the test better because RBAC, API access, SSO, hosted records, and domain grouping gave a larger team more control. For MSP-style use, the product handled multiple domains, but we still needed careful naming, grouping, and reporting conventions to keep client handoff clean.
What each tool feels like after 90 days of real use
SimpleDMARC
A practical fit for small teams starting DMARC enforcement
After 90 days, SimpleDMARC felt like a product built to get DMARC reporting under control without a long rollout. We were able to add the corporate domain, marketing subdomain, and parked domain quickly, verify Microsoft 365 and Google Workspace, and get useful aggregate views without training several teams.
The tradeoff showed up when our test cases needed interpretation. The unknown sender, SPF pass with visible-from mismatch, and forwarded-mail SPF failure were visible, but our team still had to decide the owner, document the reason, and translate the report into next steps before policy movement.

OnDMARC
A stronger fit for teams that need hosted records and enforcement governance
After 90 days, OnDMARC felt stronger once the environment stopped being simple. SendGrid, Mailchimp, the support desk sender, and the forwarded-mail SPF failure had clearer supporting context, and hosted SPF made the SPF lookup problem feel like part of the product workflow rather than a separate DNS cleanup task.
The tradeoff was product density and pricing opacity beyond Express. We spent more time learning where to find the right report and how to structure domain groups, but the enterprise workflow was stronger when we needed escalation, API access, hosted MTA-STS, and a defensible path toward reject.

Strong hosted SPF workflow
Clearer forwarding explanation
Better enterprise controls
Useful support-led enforcement

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Guided sender fixes
SimpleDMARC surfaced our Mailchimp ownership gap, but more of the fix lived outside the product; Suped's product pairs sender identification with the DNS change and owner handoff.
Alerts that match enforcement risk
OnDMARC gave useful smart alerts, but our forwarded SPF and spoof cases still needed careful routing; Suped's product focuses alerts on issues that change enforcement readiness.
MSP handoff workflow
Both products handled multiple domains, but client-style account separation and repeatable handoff notes took extra work in our test; Suped's product has MSP workflows and per-domain pricing for that operating model.
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.
