✓ Add context, re-score, and use it again on any email you write

More than a rewritten paragraph.

Every change traces back to a specific line in your score. Nothing is rewritten on taste.

Why the score means something

Most AI feedback on cold email is opinion with a number stapled on. Email Grader Pro runs one fixed rubric, built from a documented evidence base and used in both directions, to grade your email and to rebuild it.

That evidence base includes:

Five peer-reviewed field experiments covering personalisation, question-asking, reasons-why and sender authority.
Seven large-scale industry datasets covering more than 290 million sent emails, from Gong, Belkins, Hunter, Boomerang, Yesware and Outbound Squad.
The official bulk sender rules published by Google, Yahoo, Microsoft and Apple, which decide whether your email reaches the inbox at all.
Ten canonical direct response texts, from Hopkins and Caples through to Predictable Revenue.

What is the email scored on

Relevance and targeting (25%)
Whether this email is clearly for this person right now, rather than a message anyone could have received.
Problem-led (20%)
Whether it opens on a problem the reader actually recognises, instead of on you, your company or your product.
CTA quality (20%)
Whether there is one clear, low-effort next step that matches how cold the relationship is.
Proof and credibility (15%)
Whether there is a reason to believe you, such as a comparable customer or a real number, rather than a claim on its own.
Brevity and readability (10%)
Whether it is short enough to read on a phone in one pass, around 50 to 125 words, carrying one idea.
Subject line (10%)
Whether it looks like a normal internal email, and whether the body actually delivers what it promised.

Stronger evidence carries more weight in the score than popular tactics with nothing behind them. Every judgement in your result is tagged with the level of evidence supporting it, so you can tell a proven finding from a common habit.

The rubric is also checked against real cold emails with known reply outcomes, including cases where the winner was the email most people would have bet against.

Additional information

Claude Skill	Email Grader Pro is a Claude skill, so it runs inside Claude rather than on a separate website or app. It works on any Claude plan, including the free one, as long as code execution is enabled in your settings. Installation takes a couple of minutes and your delivery email includes written instructions plus a short video. Once it is added, you paste in a cold email and the grader runs.
