Mailshade

Block email tracking pixels. See who tried to track you. Gmail, Outlook, Superhuman, Yahoo, ProtonMail.

Stop email tracking pixels — and see who's been tracking you. Every marketing email you open quietly tells the sender exactly when, where, and how often you read it. Most of us never agreed to that. Mailshade blocks the tracking pixels and link redirectors that newsletters, sales teams, and CRM tools use, then shows you a clear, beautiful report of who tried to track you and how often. It works across six webmails out of the box — Gmail, Outlook (consumer and Office 365 web), Superhuman, Yahoo Mail, and ProtonMail — with one consistent UI in every inbox. TOP 5 FEATURES - Multi-client tracker blocking. One extension, six webmails. Each client is opt-in during onboarding — Mailshade only requests access to the inboxes you actually use. No <all_urls> permission. - Live in-inbox indicators. A subtle eye icon appears on every email that contained a tracker, with the vendor name surfaced on hover. An opened-email banner shows exactly how many pixels and link trackers Mailshade blocked. - Sender-level analytics. The Report dashboard rolls 7, 30, and 90 day windows by sender — "HubSpot tracked you 18 times this week" — so you can decide who to unsubscribe from with data, not gut feel. - Link-tracker unwrapping. Click a tracking link and Mailshade shows you the real destination first. Open directly to skip the tracker, open original if you prefer, or whitelist the sender if you trust them. - Privacy-first by default. Nothing leaves your machine. Blocked events are stored locally in IndexedDB. No analytics, no telemetry, no third-party servers in the data path. The code is open source under AGPL-3.0. HOW MAILSHADE COMPARES - Versus Ugly Email and PixelBlock — Gmail-only, both barely maintained. Mailshade covers Outlook, Superhuman, Yahoo, and ProtonMail as well, with active development and a sender-level dashboard neither offers. - Versus Trocker — multi-client and free, but the UI is dated, there's no Superhuman support, and no per-sender analytics. Mailshade adds Superhuman, a Recharts-driven dashboard, and link unwrapping. - Versus Gblock — paid, Gmail-only, no link-tracker unwrapping. Mailshade is multi-client AND ships link unwrapping in every tier. HOW IT WORKS 1. Install. The extension boots with zero host permissions. 2. Opt in. Pick the mail clients you use. Mailshade asks for one specific host permission per client you select — never broader. 3. See the eye icons. Open your inbox. Trackers are blocked at the network layer (declarativeNetRequest), an eye icon marks every email that tried to track you, and an opened-mail banner totals the blocked pixels and links. PRIVACY AND OPEN SOURCE Mailshade does not read your email content. It only intercepts outbound requests to known tracking-pixel domains and tracking-link redirectors. Blocked events are stored locally in IndexedDB and never leave your machine. Settings sync across your Chrome instances via chrome.storage.sync — that's it.
