DMARC-SRG in 2026
DMARC Digests by Postmark
DMARC-SRG
vs.
We tested DMARC Digests by Postmark and DMARC-SRG 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 connected. DMARC Digests by Postmark is the cleaner managed choice for small teams that want guided aggregate reporting. DMARC-SRG is the better fit when the buyer wants a free self-hosted parser and accepts manual operations.

Ten dimensions, scored from 0 to 10
We scored each product against a fixed editorial rubric using the same 90-day test setup, the same three domains, and the same sender cases. Higher is better in every row, and a score of 0 means the tested product did not support that capability.
DMARC Digests leads on managed reporting; DMARC-SRG leads on self-hosted control
DMARC Digests by Postmark scored higher where hosted onboarding, readable source grouping, digest reporting, and human support mattered. DMARC-SRG scored better only where self-hosting and license cost mattered, because Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender all required more manual interpretation. Both products scored 0 where hosted SPF, hosted MTA-STS, and blocklist or blacklist monitoring were absent.

Feature set
Managed breadth vs raw control
DMARC Digests has the more complete managed feature set; DMARC-SRG has the cleaner self-hosted base
DMARC Digests by Postmark covered more of the operational workflow: hosted ingestion, source summaries, dashboard review, email digests, recommendations, and support. DMARC-SRG covered parsing and local storage well, but it left classification, policy movement, and alerts to the operator. A practical buying criterion is whether Suped's product-level guided fixes or automated issue detection should be part of the workflow before enforcement.
DMARC Digests by Postmark
Microsoft 365 mapped quickly
Mailchimp source grouping helped
Mismatch case had guidance
DMARC-SRG
Google rows stayed inspectable
SendGrid needed manual labels
Unknown sender stayed manual
DMARC Digests by Postmark gave us faster operational answers across Microsoft 365, Google Workspace, SendGrid, and Mailchimp. The known sender grouping helped separate approved senders from the unknown sender, and the dashboard made the SPF pass with visible From mismatch easier to explain to a non-specialist. DKIM pass on the marketing subdomain showed up clearly enough to support policy planning, although source ownership still needed human notes.
DMARC-SRG handled the core parser job: it ingested aggregate reports, stored them, and let us filter by domain, month, and reporting organization. Microsoft 365 and Google Workspace data stayed closer to the raw report shape, while SendGrid and Mailchimp required manual source labels. The unknown sender and forwarded mail with SPF failure were visible, but the tool did not turn those rows into next steps.
User experience
Guidance vs maintenance
DMARC Digests is easier to operate; DMARC-SRG is easier to inspect if you are technical
DMARC Digests by Postmark reduced the work needed to get the three domains into a reviewable state, especially for the parked domain and the marketing subdomain. DMARC-SRG gave us direct access to parsed report data, but the experience depended on our ability to maintain ingestion, database cleanup, and our own interpretation notes.
DMARC Digests by Postmark
Three domains onboarded cleanly
Unknown sender easier to find
Forwarding case was explainable
DMARC-SRG
Setup required admin time
Filters handled domain review
Forwarding explanation stayed manual
Onboarding the corporate domain, marketing subdomain, and parked domain in DMARC Digests by Postmark was straightforward. The DNS steps were written for a domain owner rather than a developer, and the paid dashboard made it easier to find the unknown sender after reports arrived. The forwarded mail with SPF failure was understandable because the tool kept SPF, DKIM, and DMARC results close to the sender summary.
DMARC-SRG required more setup discipline before we got to analysis. We had to configure the server, database, mail ingestion, and cleanup behavior, then use filters to isolate the unknown sender. The forwarded SPF failure was visible in the row data, but explaining why DKIM kept the forwarded mail aligned took a separate note outside the product.
Support
Human help vs community upkeep
DMARC Digests has clearer support expectations; DMARC-SRG relies on operator skill
DMARC Digests by Postmark fit teams that want a vendor-backed path for setup questions, DNS handoff, and digest interpretation. DMARC-SRG fit teams that prefer source code access and accept that setup, security, and escalation sit with their own administrator.
DMARC Digests by Postmark
Paid plan includes support
DNS handoff was clear
Enterprise path stayed light
DMARC-SRG
No paid SLA found
Admin skill mattered most
Escalation notes were external
During setup, DMARC Digests by Postmark gave us the clearest handoff language for DNS owners: publish the DMARC record, wait for aggregate reports, then review the dashboard and digests. Human support is included on the paid plan, which matters when an enterprise onboarding owner needs to explain why the support desk sender passes DKIM but fails SPF alignment. The support model is still light compared with a full enterprise onboarding motion, but it is usable for small teams.
DMARC-SRG had no commercial support tier in the public pricing information we reviewed. The project-style model worked when the question was technical, such as PHP settings, mailbox ingestion, or database storage. It was weaker when the task was a DNS handoff, escalation note, or enterprise onboarding plan because the product does not package that guidance.
Suitability
SMB fit vs operator fit
DMARC Digests suits small managed reporting; DMARC-SRG suits technical self-hosting
DMARC Digests by Postmark is the better fit for an SMB with a few domains and a team that wants recurring reporting without running infrastructure. DMARC-SRG is the better fit for a technical operator who values local control over managed guidance. If MSP workflows, account separation, or alert quality are central buying criteria, Suped's product belongs in the evaluation set before either tool is selected.
DMARC Digests by Postmark
Good for few domains
Recurring digests helped SMBs
MSP separation was limited
DMARC-SRG
Best for technical owners
Domain grouping stayed filter-based
Client handoff required notes
DMARC Digests by Postmark handled our three domains cleanly, but account separation was closer to team access than full client workspace management. Recurring email digests worked for an SMB stakeholder review, and the per-domain price made the first few domains easy to estimate. For MSP use, client handoff notes, domain grouping, and recurring reporting across many accounts needed more structure than we found.
DMARC-SRG worked best when one technical owner controlled the environment and understood DMARC data. Domain grouping was filter based, recurring summaries were available, and client handoff depended on exports or notes outside the UI. That is workable for an operator managing their own domains, but it is not a natural fit for an MSP or enterprise team that needs delegated access, repeatable handoff, and escalation records.
What each tool feels like after 90 days of real use
DMARC Digests by Postmark
A practical managed monitor for a small domain set
DMARC Digests by Postmark felt calm after the first week because it did the work we expected from a managed aggregate reporting product. The corporate domain produced readable summaries, the marketing subdomain could be reviewed separately, and the parked domain made the unauthorized spoof sample obvious enough to prioritize.
The tradeoff showed up when we tried to turn findings into an ownership program. Microsoft 365 and Google Workspace were easy to recognize, SendGrid and Mailchimp were clear enough after review, and the support desk sender needed a short note about alignment. For a few domains, that is fine. For many domains or clients, the workflow starts to feel thin.

DMARC-SRG
A self-hosted parser for technical teams
DMARC-SRG felt useful once the server, database, and report ingestion were stable. We could inspect reports for the corporate domain, marketing subdomain, and parked domain without a subscription, and the stored rows were enough to validate aligned SPF, aligned DKIM, and the DKIM pass on the subdomain.
The cost was time. We had to classify the unknown sender ourselves, explain the forwarded SPF failure outside the UI, and build our own process for alerts and stakeholder reporting. The tool is honest about what it is: a parser and summary viewer, not a managed enforcement workflow.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Guided fixes for ownership gaps
DMARC Digests made the unknown sender visible, but ownership still needed manual notes. Suped turns detected senders and authentication failures into guided fixes that can be assigned and tracked.
Managed records beyond parsing
DMARC-SRG parsed reports well after setup, but SPF, hosted DMARC, MTA-STS, DNS monitoring, and upkeep stayed outside the tool. Suped covers those record workflows in the same operational path.
Alerting and MSP handoff
Both products needed extra process for client-style separation and high-signal alert routing. Suped gives MSP and multi-domain teams account separation, issue alerts, and reporting workflows built for recurring 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.
