Connect Enhanced Protection
Connect Gmail and OpenShield watches your Spam folder itself, reporting the clearly dangerous senders for you — no button to click. It never modifies or deletes anything in your mailbox.
Turn on automatic protection →Want more detail right in your inbox?
The extension adds a warning banner the moment you open a message from a known-bad sender, plus one-click manual reporting for anything Enhanced Protection hasn't seen yet.
Install OpenShield for Chrome or Edge. It lives quietly next to your inbox — Gmail and Outlook web supported today.
The extension only reads the sender domain and headers of emails you explicitly report. Nothing else is touched.
Open a spam email, click "Report to OpenShield", and watch it enter the public escalation lifecycle.
Follow domains, get the weekly Spam Report, and vote on what ships next.
