Blocking it means stopping that pixel request before it leaves your browser, not just labelling the message after the fact. The reliable way to do that is an extension that uses Chrome's declarativeNetRequest API to cancel requests to known tracker-pixel domains at the network layer. Mailshade does exactly this across six opt-in web clients — Gmail, Outlook, Office 365, Superhuman, Yahoo Mail and ProtonMail — so those known-domain requests send no open signal. DOM scanning also detects pixels and tracking links in opened messages; for a recognized redirect, Mailshade lets you choose the direct destination or original URL. A local per-sender dashboard records detected tracker occurrences. This guide explains what to block, why network-level blocking beats a warning icon, and how to confirm it is working."}],"$L10","$L11","$L12"]}]]}]
13:T50a,<h2>What Mailshade handles</h2><p>Two mechanisms: open-tracking pixels (tiny images whose load tells the sender you read the message) and click-tracking redirects (URLs that route through the sender's server before the real destination). DNR blocks requests to known pixel domains. For a locally detected tracking link, you choose the direct destination to avoid the redirect or keep the original URL.</p><h2>Steps to block email tracking</h2><ol><li>Install Mailshade from mailshade.org and opt into the mail clients you use.</li><li>Open Gmail, Outlook, Office 365, Superhuman, Yahoo Mail or ProtonMail.</li><li>Open a message you expect to be tracked; requests to known tracker-pixel domains are cancelled via DNR.</li><li>Check the red-eye overlay to see what the DOM scan detected.</li><li>Open the dashboard to review sender-level detection history.</li></ol><h2>Why blocking beats warning</h2><p>Tools that only flag a known tracker let its pixel load anyway. DNR cancellation means a request to a known tracker-pixel domain sends no open signal.</p><h2>Confirming it works</h2><p>Use Chrome DevTools or a controlled test message to verify that the known tracker request is cancelled. The dashboard is a detection history, so it is useful context but not by itself network proof.</p>10:["$","div",null,{"dangerouslySetInnerHTML":{"__html":"$13"}}]
