Denominator Decoder · Evidence system

See what your cold email reply rate actually means.

Paste any reply-rate number, yours or a vendor's, say what it was divided by, and get it re-expressed on a stated denominator against dated, sourced benchmarks. No email gate and no AI interpretation.

The star mechanic

Decode a reply rate.

A reply-rate figure without a stated denominator is not a metric. Enter the number and what it was divided by. The decoder normalizes it against sourced benchmark bands, or tells you honestly when the comparison cannot be made.

Ungated strategy check

How many of your outbound rules rest on unverified claims?

Select the claims that currently drive your cold-email process. This is an evidence-exposure score, not a deliverability or performance score.

Structured feedback

Did the evidence record help?

One evidence layer

Every verdict and every benchmark comes from the same versioned dataset as the Claims Index.

The decoder, the checker, and the Index are generated from one claims file. Each record has a stable ID, aliases, verdict, finding, primary source, action, category, evidence status, first and last review dates, research version, and change note.

Questions about the decoder

Why does it sometimes refuse to compare my number?

An opens-based or unique-opener reply rate cannot be honestly converted to a per-send figure, because Apple Mail Privacy Protection inflates opens. When the denominators cannot be reconciled, the decoder says so rather than inventing a conversion.

Are the benchmarks or verdicts produced by AI?

No. Every band and verdict is a human-reviewed record from the same versioned dataset as the Claims Index. The normalization is deterministic arithmetic and taxonomy lookup, not a model call.

How often is the evidence reviewed?

The active dataset is reviewed at least quarterly and whenever Belkins, Instantly, Pin, or Saleshandy publishes a newer benchmark. Each record shows its last review date and change note.
