Dead Letter — Signal Surveyor

Your reach dropped. We tell you why. Algorithm intelligence for creators (and a consumer mode for the rest).

Every time you open Instagram, Reddit, TikTok, or X without choosing to — the algorithm triggered you. Dead Letter makes that visible. Signal Surveyor v2 intercepts your Gravel sessions — the ones the trigger loop sent you to, not the ones you chose. Before the page loads, it surfaces what that session actually costs. ───────────────────────────────────────── TWO MODES. ONE MECHANIC. ───────────────────────────────────────── CONSUMER MODE (the original) Before the page loads, surfaces three numbers: 6.2 hours per day — average daily social media consumption 47 days per year — what that compounds to annually 41% — the proportion of the average feed classified as outrage or negative-sentiment content Then offers two options: → Run a free 30-second Algorithm Profile at getdeadletter.com and see your personal Vulnerability Score — a 0–100 rating of your susceptibility to algorithmic manipulation, plus your Content Diet breakdown and Chemical Signature. → Start the Signal Stack — a free 7-day neurochemical recovery protocol, one action per day, grounded in peer-reviewed neuroscience. CREATOR MODE (new in v2) For earning creators losing reach. Every time you open a platform without a posting or analytics intent, you're feeding the algorithm data about your own audience's attention. Creator mode surfaces: 62% — average reach drop this quarter for mid-size creators 3.4× — scroll time vs create time for most publishing accounts $0 — what passive scrolling pays you Then offers: → Run a free 30-second Reach Audit at getdeadletter.com — we tell you what the algorithm did to your account this week and why → Join the Signal Reports waitlist — weekly AI-generated reach intelligence, $9/mo at launch. Early access = free for life. Choose your mode on first install. Switch any time from the popup or from inside any interception overlay. The extension auto-promotes to creator mode if you visit creator dashboards (YouTube Studio, Instagram Insights, TikTok Analytics) more than twice in a week. ───────────────────────────────────────── WHAT STAYS THE SAME ───────────────────────────────────────── Or enter anyway. That's always available. It's logged. The extension tracks every interception and every time you entered anyway. That ratio — your build rate — is the only number that matters. The popup shows your Signals Intercepted count, your Entered Anyway count, and your Resistance Rate with a live bar. The data is yours, stored locally. Nothing leaves your browser without your action. Dead Letter does not block anything. It does not lecture. It does not gamify your screen time with streaks or scores. It shows you the cost at the only moment the cost is legible — after you decided to go, before you arrived. This is not willpower. This is neurochemistry. Kill the noise. — getdeadletter.com
