The Problem

Your reach isn't random.
It's a scoring problem.

Every platform scores your content across four signals — Dopamine, Oxytocin, Serotonin, Endorphin — and rewards the mix your niche is responding to right now. When your mix drifts from what's rewarded, reach quietly dies. DeadLetter finds the gap.

Dopamine

Dopamine overweight

Every post chases the same first-second hook. When your mix over-indexes on attention-grabs in a niche that's rewarding depth, the algorithm caps your reach.

Fix → add a save-worthy carousel

Oxytocin

Oxytocin starvation

Few of your posts invite a reply, and you've stopped answering the ones you get. Low creator-side conversation reads as a dead audience — and reach follows the conversation.

Fix → ask, then reply to every answer

Serotonin

Serotonin shift missed

Your niche moved toward longer, save-worthy content and your mix didn't follow. Shallow posts stop earning saves — and saves are what extend reach.

Fix → audit your last 10 for saves

Endorphins

Endorphin blind spot

No CTAs, no behavior-change asks. Content that never asks the viewer to do anything gives the algorithm no completion signal to reward.

Fix → one action CTA per week

How it works

Ninety seconds to your diagnosis.

Answer a few questions about your last 10 posts — add an analytics screenshot for a measured read — and DeadLetter scores your content against your niche's rewarded mix.

  1. Step 01

    Pick your platform

    Choose Instagram, TikTok, YouTube or X, then your niche and size band. No login, no connecting accounts.

  2. Step 02

    Drop a screenshot (optional)

    Add an analytics screenshot for a measured diagnosis. AI vision reads the numbers, then discards the image — it's never stored.

  3. Step 03

    See your channel mix

    Your Dopamine / Oxytocin / Serotonin / Endorphin split versus what your niche is rewarding this week — with a reach-delta verdict.

  4. Step 04

    Get your three moves

    The specific changes that bring reach back, ranked by impact for your niche. Re-run anytime — or get them weekly with Signal Reports.

“We don't tell you to post more. We score your content against what your niche is actually rewarding — then hand you the three moves that bring your reach back.”

Frequently Asked Questions

What is DeadLetter?
DeadLetter is a free Reach Audit for creators. Pick one platform, tell us your niche, and answer a few questions about your last 10 posts — optionally dropping in an analytics screenshot. In about 90 seconds it scores your content's channel mix (Dopamine, Oxytocin, Serotonin, Endorphin) against what your niche's algorithm is rewarding, and hands you three moves to recover reach. No login or account required.
Why is my reach dropping?
Usually because your content's signal mix has drifted from what your niche rewards right now — too many hooks and not enough save-worthy depth, no questions to your audience, unanswered comments, or no clear call to action. The audit pinpoints which of these suppression patterns is dragging you down and ranks the fixes.
What's in the audit?
A reach-delta verdict, your four-signal channel mix versus your niche's rewarded mix, the top suppression patterns hurting you, and three specific recovery moves. Upload an analytics screenshot for a measured diagnosis; skip it for an estimated one. The audit sharpens once you have 30+ posts of history.
Is DeadLetter free?
Yes. The Reach Audit is completely free — no credit card, no account. Optional weekly Signal Reports start at $4.99/mo, and the Signal Stack PDF is a one-time $9.
Does DeadLetter access my social media accounts?
No. DeadLetter never connects to or scrapes your accounts. The audit runs on your answers, plus an optional analytics screenshot you choose to upload — which is read by AI vision and then discarded, never stored.
