Valimail vs.
Centera DMARC Compliance in 2026

Valimail's source library did most of the sorting for Microsoft 365 and Google Workspace within the first reporting cycle. SendGrid and Mailchimp were identified by service name after we approved the relevant DKIM selectors. The SPF pass with a matching visible From domain and the DKIM pass with a matching d= domain were quick approvals; the SPF pass with visible From mismatch was called out as a failure to trust for DMARC policy movement. The unknown sender still needed owner research, but the UI gave enough sender, receiver, and volume context to decide whether it was a forgotten support desk integration or abuse.

Centera DMARC Compliance covered DMARC report collection, SPF, DKIM, DNS monitoring, spoof visibility, IP reporting, and SPF Protect. Microsoft 365 and Google Workspace were visible quickly, but SendGrid and Mailchimp needed more manual labeling in our test, and the DKIM pass on a subdomain was visible without as much guidance on whether to inherit policy, create a subdomain rule, or contact the sender owner. The unauthorized spoof sample was easy to isolate in the forensic view, while the unknown sender stayed a manual classification task.

We added the corporate domain, marketing subdomain, and parked domain with a clear DMARC record flow in Valimail. The parked domain moved to a stricter posture fastest because it had no legitimate traffic, and the marketing subdomain needed review after Mailchimp appeared under expected sending. Finding the unknown sender took three clicks through source and receiver views, while the forwarded SPF failure was easier to explain because DKIM still passed on the original sender.

Centera's setup felt lighter at first because the product stayed close to DMARC reporting and DNS monitoring. The three domains were visible after reports arrived, but source grouping required more naming work, especially for the support desk sender and the unknown sender. The forwarded SPF failure appeared as an SPF problem first, so we had to add a note explaining that forwarding breaks SPF and that the decision depended on DKIM and the final DMARC result.

Valimail's support path made the most sense once we treated the setup as an enterprise rollout. DNS handoff notes for Microsoft 365, Google Workspace, SendGrid, Mailchimp, and the support desk sender were easy to package for the DNS owner, and paid tiers introduced onboarding assistance, account management, and escalation language that matched a security program. The free tier was useful for monitoring, but the support expectation changed once we asked for enforcement help and add-on access.

Centera's published support posture is more direct: Danish technical support by phone and email, with DMARC configuration and SPF Protect help close to the product. In our test, that fit the SPF record handoff better than large account planning, but enterprise onboarding details, API support, SSO, SLA language, and multi-client escalation paths were not clear. The DNS owner could follow the SPF Protect instructions, while the security owner still had to write the DMARC policy plan.

Valimail suited the enterprise path in our test because the corporate domain and marketing subdomain could be grouped around approved services and policy movement. Account separation was workable through roles and higher-tier portfolio concepts, but recurring reports and MSP-style client grouping did not feel like the main use case. For SMB use, the free tier is enough to see traffic, but paid enforcement becomes the decision point once teams want managed records and support.

Centera suited smaller operators that want to watch DMARC, track DNS records, and use SPF Protect for domains close to the 10-lookup SPF limit. It was less convincing for MSP work because multi-tenancy, recurring client reports, API access, and custom handoff notes were not clear in public materials or our test flow. For an SMB with one or a few domains, the product felt understandable; for enterprise and client-service work, we wanted firmer account separation and reporting controls.
