MailAuthWatch

MailAuthWatch vs dmarcian

DMARC report processing, founded by a co-author of the DMARC spec. MailAuthWatch watches the DNS records instead of processing reports, and prices per domain rather than per message. Here is how they differ, using dmarcian's own published pricing as of 1 September 2026.

Choose dmarcian when

  • You need to see every source sending as your domain, with volumes, from aggregate reports.
  • You want a vendor whose founder helped write the standard, and are happy to pay per message volume.
  • You manage two domains and will use the report-processing depth every week.

Choose MailAuthWatch when

  • You watch many domains and care most about being told the day a record breaks.
  • You want a flat price that does not rise with sending volume: 10 domains for $29 rather than 2 for $24.
  • You do not want a third party receiving your DMARC reports at all.

Questions

Is MailAuthWatch a good alternative to dmarcian?

For watching SPF, DKIM and DMARC records across many domains and being alerted when they change, yes: MailAuthWatch costs $29 a month for 10 domains and reads public DNS only. If you need DMARC aggregate report analysis, dmarcian does that and MailAuthWatch does not.

What does dmarcian do that MailAuthWatch does not?

dmarcian processes DMARC aggregate reports, so it can show which sources are sending as your domain and in what volume. MailAuthWatch deliberately does not receive reports; it measures and monitors the DNS records those reports depend on.

Can I use both?

Yes. Many teams keep a report analyser for the per-source view and use MailAuthWatch as the daily check that the records themselves are still correct, since a broken record is what most report anomalies trace back to.
