SimpleDMARC handled the managed reporting job better out of the box. Microsoft 365 and Google Workspace appeared as recognizable sources within the first reporting window, SendGrid and Mailchimp grouped cleanly after we approved their DKIM domains, and the unauthorized spoof sample was easy to separate from legitimate traffic. The unknown sender still needed human classification because the display name and reverse DNS were not enough to prove ownership, and the DKIM pass on a marketing subdomain required a manual note before policy movement.

Parseddmarc gave us lower-level control. It parsed Microsoft 365, Google Workspace, SendGrid, and Mailchimp aggregate reports into JSON and CSV, then pushed clean events to our index. It did not decide whether the unknown sender was approved, and the SPF pass with visible from mismatch was visible as data rather than a guided remediation item.

SimpleDMARC onboarding was the quicker path for our primary corporate domain, marketing subdomain, and parked domain. The DNS screens made the required DMARC records clear, the unknown sender was findable with source filters, and the forwarded-mail SPF failure was visible in drilldowns. The caveat was explanation: we still had to write the note that DKIM passed and the forwarding path explained the SPF failure.

Parseddmarc onboarding started with mailbox access, configuration, storage, and dashboard choices. After we connected Microsoft Graph and Gmail API paths, parsing was reliable, but finding the unknown sender meant querying output data rather than clicking through a guided source view. The forwarded SPF failure was present in the parsed fields, but the operator had to connect that evidence to a stakeholder-ready explanation.

SimpleDMARC's paid tiers set expectations clearly: Basic, Standard, Priority, and Dedicated support. In our DNS handoff test, the SPF and DMARC record instructions were clear enough for an IT admin, but escalation detail depended on plan level. Enterprise onboarding was clearer than Parseddmarc because SSO, SLA, dedicated account management, and 100 active domains were public plan-card items.

Parseddmarc support was documentation and maintainer/community oriented. Installation and usage docs were good enough for an engineer to wire mailbox access, Docker secrets, and output destinations, but there was no fixed support tier, enterprise onboarding path, or DNS handoff process to give a non-specialist. Escalation meant owning the issue internally or using open-source channels.

SimpleDMARC worked best for one company managing its own domains. The primary domain and marketing subdomain sat together cleanly, the parked domain was easy to treat as a stricter enforcement candidate, and recurring reports were simple enough for an SMB stakeholder. For MSP use, account separation and client handoff were less complete because the work still leaned on manual notes and exports.

Parseddmarc worked best where operators were comfortable building the operating model. Index prefixes helped separate client or domain groups, and custom exports gave us control over reporting packages. For enterprise and MSP use, that control came with work: recurring reports, client handoff notes, alert thresholds, and escalation summaries all needed custom process outside the parser.
