Dmarcian was founded by a co-author of the DMARC spec. We are not going to pretend otherwise.
That is not marketing, and there is no version of this page where we out-credential it. Provenance does not settle two questions. What does each platform host for you instead of merely checking? And what are you billed for? We bill per domain and they bill per message, so the cheaper option depends on your shape.

Their ladder has a step in it. Find out whether you are standing on it.
Basic covers two domains at roughly $19.99. Plus is roughly $199 for eight, and their Enterprise is roughly $499 for fifteen — the figure ours starts at with no domain cap.
At 5 domains, DDMARC is $170/mo cheaper — $2,040 a year. Their figure is approximate and varies by currency and region, and it is metered on messages — check what your own volume does to it. That is on list price; their Plus tier also includes a year of report history and a message allowance, so it is not a like-for-like tier.
List prices, monthly, at the stated domain count. Plans are not like for like: see the matrix for what each includes.
Four things, not thirty-seven rows.
Both products parse aggregate reports into named senders, monitor SPF and DKIM, generate the records you publish and walk you toward enforcement. Listing those as wins would be padding. These are the differences to weigh.
Managed MTA-STS and BIMI hosting
Both of us will tell you your MTA-STS policy is missing. We will also host the policy endpoint and the BIMI logo, with the certificate renewals that go with them; Dmarcian gives you the tooling and leaves you to stand up and maintain those endpoints yourself.
API and audit log without an enterprise contract
On Dmarcian, role-based access, audit logs and API access are Enterprise-only. Our activity log is on every plan and the API starts at Protect, which matters if you are an MSP, or a team that needs scoped access before it needs a salesperson.
Per domain versus per message
Their ladder steps from roughly $19.99 to roughly $199 and then $499, and both the domain count and the message volume can trigger it. Ours moves one rung at a time and only when you add domains.
ARC monitoring and the policy simulator
ARC tells a forwarded message apart from a spoof; the simulator models p=reject against last month’s real traffic. Both are the tools you reach for at the moment you would otherwise stall.
Where Dmarcian is the better buy.
If none of these is you, switching costs an afternoon and no data: DMARC reports are generated by receiving providers, so migrating is a change to one DNS record. Ask and we will do the bulk of it at no charge, including running both platforms in parallel while you decide — the offer and the details are below.

“Not documented” means we could not find it stated in Dmarcian’s public materials, not that it is absent. Competitor facts verified from public sources, including Dmarcian’s pricing page, in September 2026— if something here is out of date, tell us and we will correct it.
The questions that decide it.
On provenance, yes: Dmarcian was founded in 2012 by a co-author of the DMARC specification and has extensive public documentation. What that does not settle is what the platform hosts on your behalf, what an API costs you, or how the bill behaves as you grow — which is what the rest of this page is about.
Run both for two weeks.
Point the same domain’s reports at both platforms — DMARC lets you send to more than one address. Two weeks of side-by-side data settles this better than any comparison table, including this one.
