PlainDMARC vs Dmarcian (for agencies, as of August 2026)
Dmarcian is the incumbent — founded by a co-author of the DMARC specification, with deep deployment tooling and years of trust. PlainDMARC is a young, deliberately narrow Dmarcian alternative. The honest difference for agencies is price shape: Dmarcian tiers by domain count and message volume, so a 10-domain portfolio lands in its $600/mo Enterprise tier, while a flat plan stays at one number.
Side by side
| Tool | Pricing model | 1 domain | 10 domains | 25 domains | White-label client reports? | Notes |
|---|---|---|---|---|---|---|
| Dmarcian | Tiered by domains + message volume | Free (Personal, ≤2 domains) or $24/mo | $600/mo (Enterprise tier, ≤15 domains) | Custom (above 15 domains) | Not advertised (partner program exists) | USD. Personal free (≤2, non-business) / Basic $288/yr ≈ $24/mo (2 domains) / Plus $2,880/yr ≈ $240/mo (8 domains, 3 users) / Enterprise $7,200/yr ≈ $600/mo (15 domains, unlimited users), each also capped by monthly message volume. Retention 1 year on Plus. Partner program for MSPs. |
| PlainDMARC | Flat plans, every domain included | Free (1 domain) or $12/mo | $39/mo | $39/mo | Yes (Agency & Agency+) | Free (1 domain) / Solo $12 (5) / Agency $39 (25) / Agency+ $59 (100); 2 months free billed yearly. Weekly plain-English verdict; white-label branded client reports with weekly auto-send (opt-in) from the Agency plan. Report emails are delivery-tracked, so a bouncing client address is caught rather than silently lost. Team seats with owner and view-only roles — 1 / 2 / 5 / 10 by plan — plus client-scoped logins on the Agency plans (invite a client to see only their own domains); no separate admin role yet. |

How Dmarcian prices it
Dmarcian tiers by both domain count and monthly message volume, in US dollars. Personal is free for up to two non-business domains; Basic is about $24/mo (≈$288/yr) for two domains; Plus is about $240/mo (≈$2,880/yr) for eight domains and three users; and Enterprise is about $600/mo (≈$7,200/yr) for fifteen domains with unlimited users — each tier also capped by message volume. So a ten-domain portfolio clears the eight-domain Plus tier and lands in the $600/mo Enterprise tier; twenty-five domains is a custom quote above fifteen. Retention is one year on Plus.

What it costs as your portfolio grows
Walk a portfolio up Dmarcian's ladder and the steps are steep. One or two domains sit comfortably on the free Personal tier or $24 Basic — genuinely cheaper than our Solo plan. But the third through eighth domain move you to Plus at roughly $240/mo, and the ninth crosses into Enterprise at roughly $600/mo for up to fifteen domains, with message-volume caps layered on top. Twenty-five domains is a custom quote above that. So the same portfolio that costs $39/mo flat here runs into the hundreds on Dmarcian once you pass a handful of clients — that is the price of its depth and pedigree, not a hidden fee. The break-even is low: if you manage more than two client domains and do not need forensic-grade tooling, the flat plan wins on cost from roughly the third domain onward.
Where each one fits
Dmarcian doesn't advertise white-label client reports; it runs a partner program for MSPs instead. PlainDMARC's core feature is exactly that missing piece — a weekly verdict carrying your agency's logo, auto-sent to each client. Where Dmarcian genuinely wins is pedigree and depth: it was founded by a co-author of the DMARC specification, its deployment and diagnostic tooling is excellent, and it offers more generous seats (three on Plus, unlimited on Enterprise). For one or two domains its free Personal tier or $24 Basic also beats our Solo plan on price.
Where Dmarcian wins
Pedigree and depth. Dmarcian helped define DMARC, its deployment and diagnostic tooling is excellent, it offers more generous team seats (3 on Plus, unlimited on Enterprise, versus our per-plan caps), and volume-based pricing is arguably fairer for high-volume senders. For 1–2 domains its free Personal tier or $24/mo Basic beats our Solo plan on price.
Where PlainDMARC wins
Domain caps and price: 10 client domains exceeds Dmarcian's $240/mo Plus tier (8 domains) and lands at $600/mo Enterprise, versus $39/mo flat on PlainDMARC's Agency plan. Dmarcian also doesn't advertise white-label client reports — our core feature is a weekly verdict carrying your agency's logo, auto-sent to each client.
The bottom line: is PlainDMARC a good Dmarcian alternative?
Pick Dmarcian for depth, pedigree, and volume-based fairness on large senders. Pick PlainDMARC on portfolio economics: ten client domains that would sit at $600/mo Enterprise on Dmarcian are a flat $39/mo here, with branded client reports included.
