DomainsDoc vs dmarcian
dmarcian was founded by one of the co-authors of the DMARC specification, and it shows: for ingesting and making sense of DMARC aggregate reports, it's one of the best products on the market. DomainsDoc plays a different position. We check your DMARC record (plus SPF, DKIM, MX, blacklists, SSL, expiry, and uptime) continuously and grade the whole domain, but we don't process your aggregate reports. Depending on what you're trying to do, the right answer might be dmarcian, DomainsDoc, or honestly both.
| Feature | DomainsDoc | dmarcian |
|---|---|---|
| Bundled health grade | Single A–F grade across email auth, blacklists, SSL, expiry, and uptime | Clear domain status for SPF/DKIM/DMARC; scope is email authentication |
| Continuous monitoring + alerting | Every 6h / 1h / 15min depending on plan, alerts on any change | Continuous DMARC report ingestion and record monitoring for email auth |
| Free instant check, no signup | Full health report with grade | Free Domain Checker, SPF Surveyor, DKIM Inspector tools |
| DMARC aggregate-report analytics | We check your DMARC record and policy, but do not ingest RUA reports | The core product, best-in-class aggregate and forensic report analysis |
| Blacklist monitoring | Checked against major DNSBLs on every run | Not part of the product |
| SSL, uptime, and domain-expiry monitoring | Included in every report on every plan | Out of scope, dmarcian is focused on email authentication |
| MTA-STS, TLS-RPT, BIMI, DNSSEC checks | Part of the bundled report | Strong coverage of the email-auth side; DNSSEC is not a focus |
| Slack / Discord alerts | On Pro and Agency | Alerting is primarily email-based |
| PDF reports | On Pro and Agency | Reporting exists within the platform; check current plans for exports |
| Price | Free check; monitoring from $9/mo | Free tools and trial; paid plans from roughly $20/mo, scaling with email volume |

When dmarcian is the better choice
- You're driving DMARC to enforcement and need report forensics. Getting from
p=nonetop=rejectsafely means analyzing aggregate reports to find every legitimate sender. dmarcian's source identification and report visualization are built exactly for this, and they do it better than almost anyone. - You're an enterprise with many sending sources. Large organizations with dozens of SaaS tools sending mail, complex subdomain policies, and compliance requirements get real value from dmarcian's depth, deployment methodology, and support.
- You want vendor expertise on DMARC itself. Their team literally helped write the spec. For tricky alignment or forwarding edge cases, that pedigree matters.
When DomainsDoc is the better choice
- You care about the whole domain, not just DMARC. An expired SSL certificate or a blacklist hit hurts you just as much as a broken DMARC record. DomainsDoc bundles all of it into one grade with one alert stream, dmarcian intentionally stays in the email-auth lane.
- You want simple, predictable pricing. DomainsDoc charges per domain, from $9/mo for 5 domains, not by email volume. High-volume senders can get expensive on report-processing platforms.
- Your DMARC is already at enforcement. Once you're at
p=reject, the day-to-day job is making sure nothing silently breaks. Continuous record monitoring with Slack/Discord alerts covers that without a report-analytics subscription.
Free, instant, no signup. Then decide if continuous monitoring is worth $9/mo to you.
