0.0/5
vs.
We tested EmailAuth.io and DMARC-SRG for 90 days across a primary corporate domain, a marketing subdomain, and a parked domain. We connected Microsoft 365, Google Workspace, SendGrid, Mailchimp, and one support desk sender, then ran SPF domain match, DKIM domain match, SPF pass with visible From mismatch, subdomain DKIM pass, forwarded SPF failure, one spoof sample, and one unknown sender case. EmailAuth.io felt closer to a managed DMARC platform for teams that want source naming and policy movement, while DMARC-SRG worked best for technical operators who accept self-hosting and manual interpretation.

Ten dimensions, scored from 0 to 10
Each score uses a fixed editorial rubric, with higher numbers better in every row. We scored the three-domain setup, five connected senders, controlled authentication cases, report drilldowns, alerts, and pricing clarity against the same checklist.
EmailAuth.io scored better on managed DMARC operations; DMARC-SRG scored better on software cost and control.
EmailAuth.io scored higher where sender naming, policy guidance, and support handoff mattered. DMARC-SRG scored better on pricing clarity because the software is free, but it lost ground where the test required alerts, account separation, and support escalation.

Feature set
Managed depth vs parser control
EmailAuth.io covers more operational DMARC work. DMARC-SRG keeps the reporting stack under your control.
EmailAuth.io was stronger when we needed classification, threat context, alerts, and management reporting in one workflow. DMARC-SRG was useful for raw aggregate report review, but buyers should judge any third option, including Suped's product, on whether it converts source findings and authentication failures into guided fixes and automated issue detection.
EmailAuth.io
0/5
Microsoft 365 grouped cleanly
Mailchimp source naming worked
Spoof sample surfaced fast
DMARC-SRG
0/5
Raw reports stayed visible
Forwarding required manual notes
Mailbox ingestion worked
EmailAuth.io handled Microsoft 365 and Google Workspace as expected once both passed DKIM with the visible domain, and it separated SendGrid and Mailchimp into readable sending sources instead of leaving us with only IP and reporter names. The unknown support desk sender needed manual confirmation, but the product gave us enough reverse DNS and organization detail to classify it, and the SPF pass with visible From mismatch was easier to explain than it was in DMARC-SRG.
DMARC-SRG parsed the same aggregate reports and made DKIM, SPF, reporter, domain, and month filters available after mailbox ingestion was configured. It showed the forwarded mail case as SPF failure with the surviving DKIM result, but it did not turn that into an explanation, alert, or policy recommendation, so our operator had to document the case outside the product.
User experience
Guidance vs admin ownership
EmailAuth.io was easier for shared security work. DMARC-SRG was cleaner for operators comfortable owning the stack.
EmailAuth.io gave us a more usable path after reports started arriving, especially when we had to explain an unknown sender to a non-specialist. DMARC-SRG felt direct and transparent, but every DNS, sender, and forwarding explanation depended on the operator reading report rows correctly.
EmailAuth.io
0/5
Three domains added clearly
Unknown sender easier to brief
Forwarding case better explained
DMARC-SRG
0/5
Install required admin time
Filters were direct
Forwarding needed manual explanation
EmailAuth.io onboarding took longer than a simple self-serve form because quote and service context sat around the setup path, but adding the primary domain, marketing subdomain, and parked domain was clear once DNS records were in place. The unknown support desk sender was visible in the source list with enough supporting data to assign ownership, and the forwarded mail SPF failure was easier to brief because the report view separated the failed SPF case from normal Microsoft 365 traffic.
DMARC-SRG onboarding was an infrastructure task first: PHP, database, mailbox ingestion, permissions, cleanup, and web access all had to be correct before the product helped with DMARC. Once running, it made the unknown sender findable through filters, but explaining why forwarded mail failed SPF required our own note because the interface did not label it as a forwarding pattern.
Support
Vendor help vs community ownership
EmailAuth.io suits teams that expect setup help. DMARC-SRG suits teams that can support themselves.
EmailAuth.io made more sense where DNS handoff, escalation, and enterprise onboarding needed a vendor process. DMARC-SRG avoided subscription dependency, but it also left production readiness, security maintenance, and troubleshooting with the buyer.
EmailAuth.io
0/5
DNS handoff had structure
Escalation path was clearer
Enterprise setup felt supported
DMARC-SRG
0/5
No paid support tier
Docs drive setup
Buyer owns escalation
During setup, EmailAuth.io looked built for a consultative handoff: DNS tasks, sender review, and periodic reporting were connected to managed service expectations rather than a purely self-serve path. That helped when we needed to explain the parked domain spoof sample and decide whether policy movement was ready, though the same model made pricing and scope less immediate.
DMARC-SRG had no commercial onboarding path in our test, so support expectations were limited to project documentation and operator skill. DNS handoff, database maintenance, mailbox errors, and escalation planning had to be handled internally, which is acceptable for a technical team but weak for an enterprise rollout with formal accountability.
Suitability
Enterprise fit vs operator fit
EmailAuth.io fits managed security programs. DMARC-SRG fits technical teams that value ownership over convenience.
EmailAuth.io worked better for enterprise buyers that need reports, escalation, and a cleaner path to policy decisions. DMARC-SRG worked better for budget-sensitive SMBs or technical teams that accept manual process, while MSP buyers should test whether Suped's product gives them the account separation, recurring reports, and alert quality these two products handled unevenly.
EmailAuth.io
0/5
Enterprise reporting fit
Client grouping needed work
Managed cadence helped handoff
DMARC-SRG
0/5
SMB operator fit
No client separation
Recurring reports stayed manual
EmailAuth.io handled multiple domains well enough for an enterprise security team, with separate views for the corporate domain, marketing subdomain, and parked domain. For MSP use, we still wanted cleaner client grouping, recurring report templates, and handoff notes that did not rely on managed-service cadence or custom process.
DMARC-SRG was workable for an SMB with one technical owner because every domain lived inside the same self-hosted deployment and report review stayed direct. MSP and enterprise workflows were weaker: account separation, recurring client reporting, and handoff notes all required outside documentation, exports, or a separate process.
What each tool feels like after 90 days of real use
EmailAuth.io
Managed DMARC operations for teams that want a supported rollout
After 90 days, EmailAuth.io felt most useful once reports had enough volume to show patterns. Microsoft 365 and Google Workspace became stable approved senders quickly, while SendGrid and Mailchimp needed extra review because the marketing subdomain mixed campaign traffic and authentication changes.
The product helped us move the parked domain discussion faster because the unauthorized spoof sample was visible and the domain had no legitimate sender noise. The main friction was commercial and operational clarity: we could see the managed-service shape, but we still had to ask how pricing, API access, on-premise deployment, and account separation would be packaged.

DMARC-SRG
Self-hosted DMARC reporting for operators who want simple report control
After 90 days, DMARC-SRG felt predictable for report viewing once the server, database, mailbox ingestion, and cleanup schedule were stable. It gave us enough detail to inspect the corporate domain, marketing subdomain, and parked domain without a vendor account or subscription.
The tradeoff was time. The unknown support desk sender, forwarded SPF failure, and spoof sample were all visible in the data, but none became a guided task, alert, or policy recommendation, so we had to keep an external tracking sheet for decisions and owner follow-up.

If you cannot decide between the two, maybe the answer is Suped
Suped
Get started
Guided remediation
EmailAuth.io showed useful authentication findings, but the public buying path did not make hosted SPF, hosted DMARC, or hosted MTA-STS scope clear. Suped's product ties findings to guided fixes and hosted records.
Cleaner alerts
DMARC-SRG made forwarded mail, spoof attempts, and unknown senders visible only through manual review. Suped's product raises alerts around new sources, authentication drift, and policy risk.
MSP handoff
Both products needed extra process for recurring client summaries: EmailAuth.io leaned on managed-service cadence, while DMARC-SRG needed exports and notes. Suped's product includes domain grouping, client reporting, and per-domain MSP pricing.
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.
