About DmarcSignal
DmarcSignal is a working DMARC monitoring service. I built it for my own domains and my consulting clients, and I keep it open for anyone else who needs it. It's free, and it will stay free. Christian Ricci, LLC is the legal entity that owns DmarcSignal.
I'm Chris Ricci. I've spent 20+ years shipping software and running engineering teams, including at Amazon (part of the original Kindle launch), Sears, Dell, Rangespan (acquired by Google), and Holland & Barrett. Today I'm CTO at RVLVR and Indigenous Software, and advisor at Affinitiv.
The same pipeline runs sh4meful.com, a public dashboard tracking DMARC spoofing patterns. Both projects are free, and I keep them running because they're technically interesting problems and because I use them.
Based in Chicago. Reach me at info@dmarcsignal.com. I'm also on GitHub.

Privacy
DmarcSignal collects only what's needed to run the service. When you create a collector, I store the collector configuration you set up and the DMARC reports that arrive for it. Report data is processed to produce your dashboard views and is retained indefinitely unless you delete a collector, at which point the associated data is removed.
I don't sell or share account information with third parties. I don't run ad networks or analytics beyond aggregate site usage metrics (Google Analytics on the marketing site, not the app). I don't send marketing email; the only messages you'll receive are transactional (verification, weekly digest summaries you can turn off, and rare service notices).
If you want your account and all associated data removed, email me at info@dmarcsignal.com and I'll take care of it.
Terms of Service
By using DmarcSignal you agree to:
- Provide accurate information when creating an account
- Use the site and service in compliance with applicable laws
- Understand that DmarcSignal is provided as a free service, without service-level guarantees
- Accept that features and service availability may change over time
If any of these become a problem for you, close your account and email me if you want the data removed.
