Skysnag vs.
DMARC-SRG in 2026

Skysnag grouped Microsoft 365 and Google Workspace within the first reporting cycle and kept SendGrid and Mailchimp separate enough for us to assign owners. The SPF pass with visible From mismatch was flagged as a third-party sender problem rather than a clean pass, which mattered because the domain was not ready for reject. The unknown sender still needed review, but the platform gave us enough IP, hostname, and pattern context to decide whether it was a service to approve or a spoof path to block.

DMARC-SRG did the core parsing work: it ingested the reports, stored them in MySQL or MariaDB, and let us filter by domain, month, and reporting organization. Microsoft 365 and Google Workspace were easy to spot because the reporting organizations were familiar, but SendGrid, Mailchimp, and the unknown sender needed manual mapping against DNS and account records. The forwarded mail SPF failure was visible in the report data, but we had to explain it ourselves by checking the surviving DKIM result.

Skysnag's onboarding handled the corporate domain and marketing subdomain in one flow, while the parked domain took extra attention because we wanted no approved senders. DNS setup had clear target records, and after Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender started reporting, the dashboard let us move between service-level views and failing authentication cases. The unknown sender was faster to find than in DMARC-SRG, and the forwarded mail SPF failure was easier to explain because DKIM survival was shown next to the fail result.

DMARC-SRG's experience started with server work: PHP, database, mailbox ingestion, cron, and web access. Once running, it was quick for domain and month filters, and the parked domain was easy to review because the table stayed mostly empty. Finding the unknown sender meant copying IPs and hostnames into a separate workflow, and the forwarded mail SPF failure looked like a raw fail until we checked DKIM and report metadata manually.

During Skysnag setup, the handoff points were clear: DNS records, sender approval, policy movement, and support escalation. We still had to decide who owned SendGrid, Mailchimp, and the support desk sender internally, but the platform gave support-ready evidence when a record needed correction. Enterprise onboarding looked quote-led, with stronger help expected on higher tiers.

DMARC-SRG had no managed onboarding in our test. The support burden was the local administrator's job, including database permissions, mailbox access, report cleanup, and web UI protection. That was acceptable for a lab-style deployment, but it is a poor fit for a team that needs a vendor to explain DNS changes to non-technical owners.

Skysnag was stronger when we treated the three domains as separate operational objects. The corporate domain needed enforcement planning, the marketing subdomain needed sender ownership for Mailchimp and SendGrid, and the parked domain needed fast spoof review. Account separation and recurring reporting were useful for agency or enterprise teams, although partner pricing and domain expansion still needed sales confirmation.

DMARC-SRG was best when one technical owner ran the whole workflow. Domain grouping existed through filters rather than client accounts, recurring summaries were available but not packaged as client-ready reports, and handoff notes had to be written outside the app. For MSPs, that means separate deployments or a custom operating process; for SMBs, it keeps software cost at $0.
