PlainDMARC vs Dmarcian (for agencies, as of July 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 tool. 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 | Personal free / Basic $24 (2 domains) / Plus $240 (8) / Enterprise $600 (15), each also capped by monthly message volume; cheaper if billed yearly. |
| PlainDMARC | Flat plans, every domain included | $12/mo | $29/mo | $29/mo | Yes (Agency & Agency+) | Solo $12 (3 domains) / Agency $29 (25) / Agency+ $59 (100). Weekly plain-English verdict; white-label branded client reports with weekly auto-send included from the Agency plan. |

Where Dmarcian wins
Pedigree and depth. Dmarcian helped define DMARC, its deployment and diagnostic tooling is excellent, 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: 10 client domains exceeds Dmarcian's $240/mo Plus tier (8 domains) and lands at $600/mo Enterprise, versus $29/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.
