What DMARC Monitoring Actually Costs
Every DMARC monitoring vendor prices on two axes: how many domains you monitor, and how many reported messages flow through them each month. The pricing pages lead with message volume because volume tiers look generous. If you send 10,000 emails a month, "up to 100,000 messages" reads like headroom for years.
The domain axis is the one that bills you. Volume caps count DMARC-reported messages, so a low-volume sender never leaves the bottom tier. Domain caps sit at 2, 4, or 5 on most entry plans, and the plan above is rarely a small step up. If you run one product on one domain, almost anything on this page is cheap. If you run a portfolio of side projects, the same vendors quote you like a mid-size enterprise.
All prices below were read from each vendor's public pricing page on 2026-08-19. Prices move; treat anything older than a few months as a rumor.
Where the entry tiers cap out
| Vendor | Entry paid plan | Domain cap | History |
|---|---|---|---|
| URIports | $6/mo annual, $7 monthly | 5 | 30 days |
| PowerDMARC | from $8/mo ($6.42 annual) | 5 active | 1 year |
| DMARCLY | $17.99/mo | 2 | 2 months |
| dmarcian | $24/mo ($19.99 annual) | 2 | 3 months |
| EasyDMARC | $44.99/mo ($35.99 annual) | 2 | 3 months |
| DMARC Digests | $14/mo per domain | none (per-domain) | 60 days |
| Valimail Enforce | from $5,000/yr | not published | not published |
dmarcian's Basic plan allows 100,000 messages a month and 2 domains. EasyDMARC's Plus plan allows 100,000 to 1,000,000 messages and 2 domains. Both plans have volume room for a sender a hundred times your size while capping domains at a number you outgrew the weekend you registered your second project.
The worked example: eight domains, low volume
One developer. Eight domains across side projects and client work. Under 10,000 emails a month combined. Here is what each vendor charges for that on 2026-08-19, using annual billing where it exists:
| Vendor | Plan that fits 8 domains | Monthly cost |
|---|---|---|
| Postmark DMARC (free tool) | free weekly digests, per domain | $0 |
| URIports | Stone (Pebble stops at 5) | $30 |
| DMARCLY | Growth (Professional stops at 2) | $39.99 |
| DMARC Digests | 8 × $14 per domain | $112 |
| dmarcian | Plus (Basic stops at 2) | $199 |
| EasyDMARC | nothing listed fits; Premium stops at 4 | contact sales |
| PowerDMARC | nothing listed fits; Basic stops at 5 active | contact sales |
| Valimail | Enforce, "starting at $5,000/year" | ~$417+ |
Three patterns worth noticing.
The cliff is real. dmarcian charges $24 a month for 2 domains and $199 a month (billed yearly, $240 monthly) for up to 8. Domains three through eight cost you $175 a month, a 10x jump, with no intermediate step.
The sales wall arrives early. EasyDMARC and PowerDMARC both route anyone past 4 or 5 domains to a contact form. Neither publishes a per-domain add-on price. You cannot budget for what you cannot read.
Per-domain pricing scales linearly into the same wall. DMARC Digests at $14 per domain is fine at one domain and $112 a month at eight. Linear pricing is predictable, which beats a quote form, but it prices a hobby portfolio like a business line item.
What the free tiers actually cap
Free tiers exist at dmarcian (2 domains, under 1,250 messages a month, non-business use only, and they audit for it), EasyDMARC (1 domain, 1,000 messages, 14 days of history), PowerDMARC (1 active domain, 10,000 messages, 10 days of history), and Postmark's free DMARC tool (weekly digest per domain, no published cap). URIports and DMARCLY have trials instead of free tiers.
The caps to read closely are messages and history, not domains. A free tier with a 1,000-message cap stops being free the month a newsletter goes out. A 10-day or 14-day history window means a two-week vacation deletes your baseline.
Postmark's free tool deserves its reputation: genuinely free weekly summaries with no stated domain limit. What it does not do is alert you between digests. A spoofing run that starts Monday reaches you the following week.
Retention is where the real cost hides
Aggregate reports are only useful in series. A single day of data tells you which sources sent mail yesterday; three months of data tells you whether that unfamiliar source is a quarterly invoicing system or an attacker. When you move from monitoring to enforcement, you want to look back across at least one full business cycle before setting p=reject. Our guide on reading aggregate reports walks through why the timeline matters more than any single report.
Entry tiers mostly ship short windows: 30 days at URIports, 2 months at DMARCLY, 3 months at dmarcian Basic and EasyDMARC Plus, 60 days at DMARC Digests. PowerDMARC is the exception with a year of history on its Basic plan. Everywhere else, a year of history is the feature that drags you up a tier, and the tier jump is priced for companies where email is revenue infrastructure.
What you are paying for at each price point
Under $10 a month buys parsing, a dashboard, and short history on a handful of domains. That covers a developer who wants to know what is sending as their domains and whether alignment holds.
The $20 to $90 band buys longer history, more seats, and alerting. Some of that spend is capability. Some of it is packaging: SSO, audit trails, and compliance reporting bundled into the same tier as the alerts you wanted, whether or not anyone will ever ask you for a SOC 2 evidence export.
Past $100 a month you are paying for managed enforcement, deliverability consulting, and procurement-friendly contracts. Valimail's published floor of $5,000 a year says who that product is for, and it is not a person with eight side projects.
For the record, since this is our blog: dmarcdrift is $0 for 1 domain with a 7-day view, $9 a month for up to 15 domains with 180 days of history, and $29 a month for unlimited domains with a 365-day view. One price per tier, no per-domain fees. Those numbers are the reason this post exists; the 8-domain scenario above is our own founding story. For a feature-level comparison rather than a price one, see the DMARC monitoring tools comparison.
Before paying anyone, run your domain through the DMARC Record Checker to see what you currently publish. If there is no rua= address in your record, no vendor on this page has anything to monitor yet.
dmarcdrift is free for one domain. Point your rua= address at us and the first digest arrives within a week.
