## How a number earns trust

Every network scores sending numbers the way email providers score senders. High reply rates, steady volume, and two-way conversation build trust. Volume spikes, identical broadcast copy, and ignored messages destroy it. A flagged number silently stops reaching phones, and there is no appeal hotline.

## What Beam does automatically

  - Warm-up pacing. New numbers start with a conservative daily cap that grows over weeks of healthy sending.
  - Business hours. Waking-hours sending only.
  - Human timing. Sends are spaced irregularly. Perfectly even intervals are a machine fingerprint, so Beam never produces them.
  - One number per relationship. The first number a contact hears from is theirs forever.
  - Automatic opt-out. STOP ends messaging to that contact instantly.
  - Health-graded inventory. Numbers are scored before you ever lease them.

## Reading your signals

  - Reply rate (inbox header): above 20% on warm leads is healthy. Below 10% means fix the message or the list, not add volume.
  - Numbers tab: per-line health and current warm-up pace.
  - Sudden silence: if replies stop across the board, tell us immediately in your support channel. Early is fixable.

## The failure story to avoid

It always goes the same way: someone connects a big cold list, blasts identical copy from a fresh number, gets no replies, and the number is dead within days. Every rule on this page is the inverse of that story.
