MyDMARC vs.
DMARC-SRG in 2026

MyDMARC handled the managed SaaS side of the test more completely. Microsoft 365 and Google Workspace were grouped clearly, SendGrid and Mailchimp were separated into their own sender views, and the support desk sender was easy to review against the corporate domain. The DKIM pass on a subdomain was visible with enough context to explain why it was acceptable, while the unknown sender still needed manual owner assignment before we trusted a policy move.

DMARC-SRG gave us the raw building blocks: report ingestion, stored aggregate data, filters by domain and reporter, and enough DKIM and SPF detail to investigate the same cases. Google Workspace appeared in parsed reports, SendGrid and Mailchimp were visible through source rows, and the DKIM subdomain case was available for review. The product did not turn the unknown sender into a named service or an operational task, so we had to maintain our own classification notes.

MyDMARC took about 23 minutes to add the corporate domain, marketing subdomain, and parked domain, excluding DNS propagation time. The unknown sender was easy to find because it appeared in a reviewable traffic view, but the product did not fully explain who owned it. The forwarded mail SPF failure was correctly surfaced as an authentication problem, though our handoff note still had to explain why forwarding caused SPF to fail while DKIM carried the message.

DMARC-SRG took about 2.5 hours before we had a stable flow, because we had to provision PHP, database storage, mailbox access, cron processing, and cleanup settings. The unknown sender was present in the report data, but finding it required filtering and comparing IPs against our sender inventory. The forwarded mail SPF failure appeared as a failure result, with no built-in explanation that separated forwarding behavior from a direct authentication break.

MyDMARC produced DNS setup steps that were clear enough to hand to a domain administrator for Microsoft 365, Google Workspace, and the marketing subdomain. The Pro tier publishes priority email support, which gave us a clearer support expectation than the lower tiers. Enterprise onboarding details were less clear publicly, so a larger buyer still needs to confirm onboarding scope, escalation paths, and service expectations before purchase.

DMARC-SRG had no vendor onboarding path in our test. DNS handoff was something we wrote ourselves, including the rua address plan, mailbox polling details, and instructions for the support desk sender. Escalation meant project documentation and administrator troubleshooting, which works for technical operators but is weak for a buyer that expects managed setup help.

MyDMARC handled our three test domains as a single managed account and kept the corporate domain, marketing subdomain, and parked domain easy to compare. It was less convincing for MSP-style work because account separation, client grouping, and recurring handoff notes were not as strong as the core DMARC reporting experience. SMB buyers will feel the benefit sooner than agencies managing many client domains.

DMARC-SRG suited the operator profile: one team, its own infrastructure, and enough time to maintain ingestion, cleanup, backups, and access control. For MSPs, we would separate clients by instance or database conventions, then create recurring reports and handoff notes outside the product. Enterprise teams with internal tooling can work with that model, but it is a poor fit for a business user that wants ownership workflows inside the product.
