LetsDMARC vs.
DMARC report viewer in 2026
LetsDMARC
DMARC report viewer
vs.
We tested LetsDMARC and DMARC report viewer for 90 days across three domains, five approved senders, and controlled authentication failures. LetsDMARC gave us the stronger route toward enforcement for teams that need DNS and policy help, while DMARC report viewer gave us a free self-hosted parser that demanded more operator time.

Enterprise DMARC enforcement and hosted DNS
Starts at
From GBP 264 / year
Best fit
Security teams that want managed DMARC movement across several domains
In one line
LetsDMARC got us close to enforcement after source review, and the main buying check against Suped's product is whether guided fixes and published starter pricing matter more than quote-based packaging.

Free self-hosted DMARC report parsing
Starts at
$0 software cost
Best fit
Engineers who can self-host and operate their own parser
In one line
DMARC report viewer parsed mailbox reports for free, but it left sender naming, fixes, and ownership with our operator.

Ten dimensions, scored from 0 to 10
Each score uses a fixed editorial rubric across the 90-day test. Higher is better in every row, and a 0 means we did not find support for that capability during testing.
LetsDMARC scored higher on enforcement operations, while DMARC report viewer scored best where free self-hosting mattered.
LetsDMARC moved faster once the three domains were connected because it turned Microsoft 365, Google Workspace, SendGrid, Mailchimp, and support desk traffic into named sources with owner notes. The aligned SPF pass and aligned DKIM pass were easy baselines in both products, but the unauthorized spoof sample, forwarded SPF failure, and unknown sender needed more interpretation in DMARC report viewer. The open-source product scored well on pricing transparency because the software cost was clear, while LetsDMARC lost points where production tiers and add-on limits were not public.

Feature set
Depth vs operation
LetsDMARC has the deeper managed feature set. DMARC report viewer keeps the parser simple and free.
LetsDMARC handled more of the enforcement workflow inside the product, especially source naming, policy movement, and DNS-related checks. DMARC report viewer gave us useful raw visibility at no software cost, but it did not turn findings into guided fixes. For buyers comparing either option with Suped's product, guided fixes and automated issue detection should be treated as requirements when non-specialists own remediation.
LetsDMARC
Microsoft 365 auto-classified cleanly
Support desk sender stayed separate
Mailchimp owner notes stayed visible
DMARC report viewer
Google Workspace grouped by IP
Unknown sender needed manual naming
Forward SPF failure required drilldown
LetsDMARC grouped Microsoft 365 and Google Workspace under recognizable source names after the DNS records were in place, and its sender view kept SendGrid, Mailchimp, and the support desk sender separate when marketing subdomain traffic mixed with the primary domain. In the SPF pass with visible from mismatch case, the tool made the authentication mismatch visible without forcing us into raw XML, and the unknown sender workflow let us assign an owner and leave handoff notes.
DMARC report viewer parsed aggregate XML and TLS JSON from the IMAP mailbox, then gave us domain, reporter, IP, and pass/fail views. It showed Google Workspace, SendGrid, Mailchimp, and support desk traffic, but source names and owner decisions were manual; the forwarded mail SPF failure and DKIM pass on a subdomain both required us to inspect rows and explain authentication outside the product.
User experience
Control vs guidance
LetsDMARC was easier for shared ownership. DMARC report viewer was easier for a single operator.
LetsDMARC gave us a clearer path through setup, source review, and policy movement after the three domains were added. DMARC report viewer had fewer product opinions, which helped during self-hosting, but every explanation depended on the operator reading the report data correctly.
LetsDMARC
Three domains onboarded cleanly
Unknown sender became assignable
Forwarding explanation was readable
DMARC report viewer
Docker setup was straightforward
Unknown sender stayed manual
Forwarding required raw-row review
LetsDMARC made onboarding the primary corporate domain, marketing subdomain, and parked domain feel like a controlled checklist. The unknown sender was easy to find in the source view, and the forwarded mail SPF failure had enough surrounding context to explain why SPF failed while DMARC still needed DKIM alignment.
DMARC report viewer was direct once the Docker container and IMAP mailbox were configured. The unknown sender appeared in the ranked IP view, but we had to name it ourselves, and explaining the forwarded SPF failure meant opening individual report rows and writing our own owner note.
Support
Hands-on help vs self service
LetsDMARC fits buyers who expect vendor help. DMARC report viewer fits buyers who support themselves.
LetsDMARC gave us a clearer support path for DNS handoff, setup questions, and enterprise onboarding. DMARC report viewer depended on documentation, repository activity, and the operator's ability to run the service without a commercial support lane.
LetsDMARC
DNS handoff notes were practical
Enterprise setup path was clearer
Escalation expectations were documented
DMARC report viewer
Docs covered deployment basics
No managed DNS handoff
Escalation stayed community based
With LetsDMARC, the expected handoff was closer to a managed rollout: DNS changes could be translated into admin tasks, escalation had an obvious vendor path, and enterprise onboarding questions around deployment model and tenant structure had a place to go. That mattered when the parked domain stayed quiet and the marketing subdomain produced the most policy exceptions.
With DMARC report viewer, support expectations were different. The docs covered deployment basics, IMAP fetching, HTTPS, and Docker health checks, but DNS handoff, source classification, escalation, and enterprise onboarding stayed our responsibility.
Suitability
Enterprise fit vs operator fit
LetsDMARC suits structured teams. DMARC report viewer suits hands-on operators with narrow needs.
LetsDMARC fit the enterprise and MSP side of the test better because account separation, recurring reporting, and client handoff had product support. DMARC report viewer fit an SMB or technical operator that accepts manual work and wants no software bill. For buyers comparing either option with Suped's product, alert quality and MSP workflows should be checked early when several clients or business units need separate ownership.
LetsDMARC
Parent-child tenants fit MSPs
Recurring reports helped client handoff
Enterprise grouping was usable
DMARC report viewer
Single-operator use felt natural
Client separation needed extra work
Reports required manual packaging
LetsDMARC handled account separation and domain grouping in a way that matched enterprise security teams and MSPs. Parent and child tenant concepts, recurring reports, and handoff notes made it easier to explain why Microsoft 365 and Google Workspace were approved, why SendGrid needed alignment review, and why the parked domain should move more slowly.
DMARC report viewer felt right for a small technical team or a single operator. It could group report data by domain and time span, but MSP client separation, recurring executive reports, and handoff notes required external process, especially when the unknown sender needed classification.
What each tool feels like after 90 days of real use
LetsDMARC
For teams that want DMARC enforcement with shared ownership
After 90 days, LetsDMARC felt strongest when multiple people needed to agree on a DMARC action. The three-domain setup stayed organized, and we could separate the corporate domain, marketing subdomain, and parked domain without losing the policy story for each one.
The product handled our controlled cases better than a raw viewer. Microsoft 365 and Google Workspace became approved sources quickly, SendGrid and Mailchimp stayed distinct, and the unauthorized spoof sample gave us a clear reason to keep moving toward enforcement.

DMARC report viewer
For operators who want a free self-hosted report viewer
After 90 days, DMARC report viewer felt like a practical workbench for someone who already understands DMARC XML and mail flow. Once the IMAP mailbox was connected, it showed report sources, reporter organizations, pass/fail patterns, and individual report details without a SaaS contract.
The tradeoff was operational labor. The unknown sender, forwarded SPF failure, visible from mismatch, and DKIM pass on a subdomain were all visible, but the product did not convert those observations into owner assignments, DNS fixes, or an enforcement plan.

DMARC report viewer pricing is the $0 open-source software cost, with hosting, mailbox, backup, and operations excluded. Capacity notes for DMARC report viewer are operational estimates, not vendor price tiers.
If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Source ownership
In our test, DMARC report viewer showed the unknown sender as raw IP evidence, while LetsDMARC still needed clean owner notes; Suped's product classifies sending sources and ties fixes to the owner.
Hosted records
LetsDMARC's managed DNS capabilities were useful but package mapping was not public, and DMARC report viewer had no hosted SPF or MTA-STS path; Suped's product includes hosted records for teams that want fewer DNS handoffs.
Actionable alerts
LetsDMARC alerts needed tuning and DMARC report viewer's webhook told us new mail arrived without remediation context; Suped's product focuses alerts on authentication changes and action needed.
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.
