Evidence in your original email

Hi Sarah,

I wanted to introduce our leading platform which helps companies improve efficiency across their sales process.

We offer a wide range of features and would love to book 30 minutes to show you everything.

Are you free next Tuesday?

Why this reduces replies: The opening is sender-focused and the call asks for a large commitment before proving relevance.
The scoring structure

Six checks. One clear view of your email.

Each part of your cold email receives a score from 1 to 5. The percentages show how much each part contributes to the overall score.

01 / 0625%

Relevance and targeting

Is this email clearly for this person right now, rather than a message anyone could have received?

02 / 0620%

Problem-led

Does it open on a problem the reader recognises, instead of opening on you, your company or your product?

03 / 0620%

CTA quality

Is there one clear, low-effort next step that suits a relationship that is still cold?

04 / 0615%

Proof and credibility

Is there a reason to believe you, such as a comparable customer or a real number, rather than an unsupported claim?

05 / 0610%

Brevity and readability

Can someone read it on a phone in one pass? Aim for roughly 50 to 125 words and one main idea.

06 / 0610%

Subject line

Does it sound like a normal internal email, and does the body deliver on what the subject promises?

Why trust the feedback?

Grounded in published research and practical sales writing.

The grader uses a defined scoring rubric informed by research into how people respond to email, sender guidance and established direct response principles.

5

Peer-reviewed field experiments

Experimental findings across email and related persuasion settings inform the principles behind the feedback.

7

Published email analyses

Reported samples across Gong, Outbound Squad, Yesware, Boomerang, Belkins and Hunter total roughly 296 million sent emails.

Sender guidance

Current platform rules

Google, Yahoo and Microsoft sender requirements inform delivery guidance. Apple Mail Privacy Protection informs how open-rate claims are interpreted.

10

Direct response books

Established writing principles add a practical lens to relevance, proof, clarity and the ask.

What “informed by” means: the grader reviews the email you paste against the six criteria above. It does not look up your email in those publishers’ underlying datasets or predict your reply rate.

The 296 million figure adds together reported sample sizes, including analyses that may share emails. It is not a count of unique emails. A pasted message also cannot verify your domain setup or guarantee inbox placement.

Explore selected published analyses: Gong, Outbound Squad / 30MPC, Yesware, Boomerang, Belkins and Hunter. Some analyses cover email beyond cold outreach; the publishers do not endorse this product.
