dmarcian has been in DMARC since 2012, and its founders helped write the original DMARC specification. Here's exactly what each pricing tier includes, where the jumps are, and how DMARCKeeper compares.
Founded in 2012; often described as the “canon” DMARC tool because its team co-authored the original specification.
Personal is free but non-commercial only — 2 domains, and dmarcian's own audit process removes accounts it detects as business use. Basic is $19.99/month for 2 domains and 100,000 messages with 3 months of history. Plus jumps to $199/month for 8 domains. Enterprise is $499/month for 15 domains — API and SSO are only available at this tier.
Alerting is a genuine strength: Alert Central covers DNS changes, traffic spikes and abuse, delivered by email, Slack, Teams or webhook, with default alerts (SPF Invalid/Disappeared, DMARC All Changes) added since July 2025 — though none of this is on the free Personal tier.
All DNS record changes are made manually; there's no hosted or managed DNS layer.
Per SpendHound's pricing-tracking data, dmarcian's pricing rose 52% year-over-year. A review cited via emailwarmup describes the interface as “dated” with a “steep learning curve.”

The one fact worth remembering: Moving from dmarcian's Basic tier to Plus means paying roughly 10 times more ($19.99 to $199/month) for 4 times the domains (2 to 8) — the steepest single price jump of any vendor we reviewed.
Where dmarcian's price jumps roughly 10x between Basic and Plus, DMARCKeeper's checker and guides stay free at any usage level.

Live today: a free checker, plain-English explanations and /connect onboarding that works on any DNS host via a standard TXT record — no CNAME delegation, no DNS migration. Real-time alerts when a new sender appears or an existing one starts failing, a guided step-by-step path through p=none → quarantine → reject with checks at each step, and 12 months of report retention are on our roadmap for paid plans. Join the waitlist to hear when they ship.
If you specifically want the tool built by DMARC's original spec co-authors, value their sender/source classification, and your alerting needs are met by Slack, Teams or webhook without an automated wizard — that's a defensible choice, especially for a technically confident buyer who doesn't mind manual DNS work.
We built it from dmarcian's own pricing pages and public reviews, cited inline with the date we checked (2026-07-14). Where dmarcian does something better, the “When dmarcian is the better choice” section above says so directly.
Everything above was verified 2026-07-14 directly from the vendor's own site. Pricing and features change without notice — the source link above always points to the current page.
Yes. DMARC configuration lives in your domain's DNS, not inside a vendor's account — switching your rua= reporting address is a one-line DNS change either way.
