Most DMARC monitoring tools charge per domain, per month. That works fine for a single business — but if you're an agency or freelancer managing many client domains, the bill grows every time you onboard a customer. This page compares how the common plans price out across 10 domains, and where a flat-price model fits.
| Tool | Pricing model | Cost for 10 domains |
|---|---|---|
| Postmark DMARC Digests | $14/mo per domain | $140/mo |
| DMARCReport | $15/mo per domain | $150/mo |
| dmarcian | from ~$20/mo, tiered | varies |
| EasyDMARC | from $35.99/mo (annual), tiered | varies |
| PlainDMARC FLAT | Flat: Solo $12/mo (3 domains), Agency $29/mo (25 domains), Agency+ $59/mo (100 domains) | $29/mo |

Postmark offers a DMARC monitoring product priced per domain. It sends weekly digest emails summarising your aggregate reports. At around $14/mo per domain, the cost scales linearly with the number of domains you monitor. Prices as of mid-2026 — check the vendor site.
DMARCReport provides aggregate and forensic report monitoring on a per-domain basis, around $15/mo per domain. Like other per-domain tools, the total scales with your domain count. Prices as of mid-2026 — check the vendor site.
dmarcian is an established DMARC platform with tiered plans that start from roughly $20/mo and are bracketed by the number of domains and report volume. The effective cost for 10 domains depends on the tier you land in. Prices as of mid-2026 — check the vendor site.
EasyDMARC offers a feature-rich platform with tiered plans starting around $35.99/mo on annual billing, scaling by domains and sources. As with other tiered tools, the cost for 10 domains varies by plan. Prices as of mid-2026 — check the vendor site.
PlainDMARC uses flat plans that bundle multiple domains: Solo at $12/mo covers 3 domains, Agency at $29/mo covers 25 domains, and Agency+ at $59/mo covers 100 domains. For an agency running 10 domains, the Agency plan is a single $29/mo bill rather than a per-domain total.
PlainDMARC is built for agencies and freelancers who manage multiple client domains and want a plain-English weekly verdict — "your email is passing" or "here's what to fix" — instead of parsing raw DMARC XML reports. If you're onboarding new client domains regularly, a flat plan that covers many domains keeps your monitoring cost predictable while you grow.
If you only run a single domain, a per-domain tool may be perfectly economical — the flat model is designed specifically for people juggling many domains at once.
