SimpleDMARC vs.
Docker DMARC Reports in 2026
SimpleDMARC
Docker DMARC Reports
vs.
We ran both products for 90 days across a corporate domain, a marketing subdomain, and a parked domain. SimpleDMARC was the stronger managed reporting choice for teams that want faster sender classification and policy planning, while Docker DMARC Reports was useful when free self-hosting mattered more than guidance.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric based on the 90-day setup, sender classification work, policy planning, alerts, exports, support handoff, and pricing clarity. Higher is better in every row.
SimpleDMARC scored higher for managed DMARC operations, while Docker DMARC Reports scored where self-hosted control mattered.
SimpleDMARC gained points because the three test domains were faster to onboard, Microsoft 365 and Google Workspace were easier to classify, and the unauthorized spoof sample was easier to route into a policy discussion. Docker DMARC Reports gained credit for free self-hosting and raw report access, but it had no managed alerts, support path, hosted SPF, hosted MTA-STS, or blocklist (blacklist) monitoring. The biggest gap was time to enforcement: SimpleDMARC provided enough guidance for a defensible plan, while Docker required DMARC expertise outside the tool.

Feature set
Managed depth vs raw control
SimpleDMARC has the broader ready-made DMARC toolkit; Docker DMARC Reports is a focused self-hosted parser.
SimpleDMARC gave us more usable coverage for sender discovery, alerts, and enforcement planning. Docker DMARC Reports gave us report ingestion and viewing without SaaS billing, but most classification and remediation stayed manual. Suped's product is relevant when guided fixes and automated issue detection need to become owner-ready work items, not a separate analysis task.
SimpleDMARC
Microsoft 365 grouped cleanly
SendGrid ownership suggested
Forwarded SPF explained
Docker DMARC Reports
IMAP reports parsed hourly
Unknown sender stayed manual
Mailchimp rows needed review
SimpleDMARC handled the main SaaS workflow better in our test. Microsoft 365 and Google Workspace landed in recognizable sender groups, SendGrid and Mailchimp were distinguishable after we reviewed their DKIM and return-path patterns, and the support desk sender was easy to keep separate from marketing mail. The unknown sender still needed owner confirmation, but the product gave enough surrounding evidence to route it. For the SPF pass with visible From mismatch, SimpleDMARC made the authentication problem easier to explain than the raw aggregate rows.
Docker DMARC Reports did the narrow parsing job correctly after IMAP and database setup. It showed aggregate report rows for Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender, but the tool did not name ownership or recommend next steps. The unknown sender was an IP and host investigation task, and the DKIM pass on the marketing subdomain required us to map the subdomain relationship manually. That control is useful for operators, but it is thin for teams that expect source resolution.
User experience
Guidance vs assembly
SimpleDMARC is easier for business users; Docker DMARC Reports suits operators who accept setup work.
SimpleDMARC made the first week smoother because the DNS setup, sender views, and report drilldowns were connected in one hosted workflow. Docker DMARC Reports gave us control, but every step around infrastructure, access, interpretation, and explanation had to be built or documented by us.
SimpleDMARC
Three domains added quickly
Unknown source surfaced
Forwarding explanation clearer
Docker DMARC Reports
Setup required container work
Filtering found the sender
Forwarding required DMARC knowledge
SimpleDMARC took about 45 minutes to add the corporate domain, marketing subdomain, and parked domain, including DNS validation checks. The unknown sender was found by moving between source and domain views, then comparing volume, IP ownership, and authentication results. The forwarded mail case with SPF failure was easier to explain because the DKIM pass and receiver pattern were visible next to the failure rather than buried in raw report rows.
Docker DMARC Reports took about two hours before the first useful screen because we had to configure the container, database, IMAP mailbox, folder handling, and web access. Once reports arrived, filtering helped us find the unknown sender, but we still had to investigate the IP and write our own explanation. The forwarded mail SPF failure was visible, but the reason was not translated for a domain owner.
Support
Hands-on help vs self support
SimpleDMARC has clearer support paths; Docker DMARC Reports depends on internal operators.
SimpleDMARC had the expected SaaS support shape: plan-based support levels, DNS handoff material, and a clearer enterprise path. Docker DMARC Reports had no managed support path in our test, which means setup, escalation, security hardening, and interpretation all stayed inside the team running it.
SimpleDMARC
DNS handoff was usable
Priority support on paid tiers
Enterprise onboarding was clearer
Docker DMARC Reports
No managed support path
Escalation stayed internal
DNS help was self-authored
For SimpleDMARC, the practical support value was in the DNS handoff. We could give a domain owner the required DMARC record change, explain why the parked domain should stay cautious, and escalate setup questions through the paid-plan support path. Enterprise onboarding looked clearer because dedicated support and account management are public plan-card items, even though SCIM state was not clear from public plan text.
For Docker DMARC Reports, support expectations were different because it is a self-hosted image rather than a hosted service. When IMAP folder handling delayed report pickup and the database needed retention decisions, the escalation path was our own operations process. DNS handoff, enterprise onboarding, backups, patching, and access control needed internal documentation before a non-specialist could rely on it.
Suitability
SaaS buyer vs self-hosted operator
SimpleDMARC fits SMB and lean IT teams better; Docker DMARC Reports fits technical teams that want free self-hosting.
SimpleDMARC is the better fit when a team wants a hosted DMARC workflow and does not want to own the parser stack. Docker DMARC Reports is the better fit when the buyer has operators who want full infrastructure control and accept manual classification. If MSP workflows or alert quality are buying criteria, Suped's product belongs in the comparison because those gaps changed recurring handoff work in our test.
SimpleDMARC
SMB rollout felt practical
Client separation felt partial
Recurring reports were usable
Docker DMARC Reports
Self-hosting fit lab use
Client handoff was manual
No recurring report workflow
SimpleDMARC made the most sense for SMB and lean enterprise teams in our 90-day test. Domain grouping worked for the corporate domain, marketing subdomain, and parked domain, and recurring reports were usable for owner updates. Account separation was acceptable for internal teams, but MSP-style client separation and recurring handoff notes felt partial when we imagined repeating the process across many client domains.
Docker DMARC Reports made sense for technical users, labs, and teams with strict self-hosting requirements. It had no vendor-enforced domain cap, so grouping domains was an operational choice, not a plan choice. That freedom came with tradeoffs: no built-in recurring reports for clients, no account separation for MSP handoff, and no guided domain owner notes after the unknown sender review.
What each tool feels like after 90 days of real use
SimpleDMARC
A managed DMARC workspace for teams that want progress without running the stack
After 90 days, SimpleDMARC felt like a practical managed layer for a small team. The corporate domain and marketing subdomain produced enough volume to test Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender, and the product kept those streams easier to review than raw XML.
The parked domain was also useful because it made the unauthorized spoof sample stand out quickly. We still had to make some judgment calls around the unknown sender and the visible From mismatch case, but the workflow reduced the amount of manual DMARC translation needed before policy planning.
Where it wins
Fastest setup across three domains.
Readable sender grouping for major senders.
Useful DNS validation and handoff.
Public tiers made budgeting straightforward.
Where it lags
MSP account separation felt limited.
Blocklist and blacklist monitoring was absent.
Hosted MTA-STS was not available.
Some source fixes still needed interpretation.

Docker DMARC Reports
A free self-hosted parser for teams comfortable owning every operational detail
After 90 days, Docker DMARC Reports felt like useful plumbing rather than a DMARC program tool. It fetched reports, parsed them, and gave us a viewer, which was enough to inspect traffic for the corporate domain, marketing subdomain, and parked domain.
The tradeoff was constant ownership. We had to maintain the container, database, mailbox, access control, retention, backups, and every explanation for the unknown sender, forwarded SPF failure, and spoof sample. It was workable for a technical operator, but slow for stakeholder handoff.
Where it wins
No vendor subscription cost.
Runs under owned infrastructure.
Raw report access stayed available.
No vendor-enforced domain cap found.
Where it lags
No managed alerting workflow.
No guided policy movement.
No support or onboarding path.
Manual classification for unknown senders.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Owner-ready fixes
In our test, SimpleDMARC surfaced source data but some sender fixes still needed interpretation, while Docker DMARC Reports left nearly every next step with the operator. Suped's product turns DMARC findings into guided repair tasks for DNS and sending-source owners.
Cleaner alert routing
SimpleDMARC email alerts helped, but forwarded-mail and unknown-sender cases still needed triage, and Docker DMARC Reports had no managed alert routing. Suped's product focuses alerts on source changes, spoof spikes, and policy risks so ownership is clearer.
MSP handoff support
SimpleDMARC handled our domains, but client separation and recurring handoff notes felt partial; Docker DMARC Reports required a separate operational process for each client. Suped's product includes MSP workflows for domain grouping, recurring reporting, and account ownership.
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.
