OpenShield is a crowdsourced anti-spam platform that helps you report spam emails, track enforcement actions against spammers, and hold email providers accountable. Using OpenShield, you can report spam with a single click, and our system automatically sends legal notices to registrars and hosts while making cases public for community visibility.
Report spam.
We make it disappear.
One click captures the evidence. Our agents handle the legal notice, the public accountability, and — if a host won't act — a crowd-funded law firm that gets paid only on proof of takedown.
Free for individuals. No store listing yet — we'll email you the moment it's live.
Three steps. Zero cost.
One click from the extension or Outlook — captures header proof, never the message body.
The domain and its owner/host enter a public case, graded on how fast they respond.
No response in the grace window → crowd-funded legal escrow retains a real law firm, paid only on proof of enforcement.
What happens after you click report
Every stage has a published time budget — nothing sits in a queue indefinitely.
Automated forensic review confirms the report and clusters related domains.
A formal legal notice goes to the domain owner, registrar, and host with a per-provider response window.
Community-funded escrow retains a verified law firm — paid only on a DNS-verified takedown.
Outcome and timeline are published — the registrar/host's response speed feeds their public grade.
Built for procurement checklists, not just inboxes.
Bulk reporting, org accounts, API keys, webhooks, and SSO — everything your security review usually asks for is already shipped, not on a roadmap. See the full breakdown on the Enterprise page.
No cold shots, no vigilantism
Every report goes through a due-process lane before it becomes public.
Header proof and structured metadata only — never the message body.
Verified legitimate senders can't be mass-reported off the platform.
We never solicit domain owners for money to remove a listing.
Escrow retains actual verified law firms, not automated threats.
Money-safety and due-process paths carry their own test harness.
Dispute it directly — most legitimate cases resolve in under a day.

Questions, answered.
Is OpenShield free?+−
Yes — free to use. The core routing code is gated to trusted maintainers who review it regularly. Your inbox contents never leave your device, and we never sell data. Optional supporter tiers and premium security tools fund the servers.
Is this legal?+−
We never attack spammers. We escalate through official abuse channels first — owner, then registrar, then host. If they are ignored, the community can crowd-fund an escrow pot; verified local law firms bid for the job, and get paid the exact invoice amount only after they submit a court order, registrar suspension, or other verifiable proof of enforcement. Every step is logged in public.
What data do you collect?+−
Only the sender domain and structured metadata from the headers you choose to report (SPF/DKIM/DMARC results, sending IP). Raw headers are parsed and then discarded — your inbox contents never leave your device, and we never sell data.
A domain I own got listed — what now?+−
Claim it and clear it with a one-time DNS TXT record, or dispute it with evidence. Legitimate senders are whitelisted automatically.
How do you stop false or abusive reports?+−
Reporting and voting require a signed-in account and are rate-limited. Every report carries header proof, and the core routing code is gated to trusted maintainers.
Which email apps are supported?+−
Chrome & Edge extensions for Gmail and Outlook web. Yahoo and Firefox are on the roadmap.
Keep the shield running.
No trackers, no data sales. Supporters fund the servers and steer the roadmap.
