## How the Email Tester Works

Paste or forward your sales email and we'll score it across 10 categories that determine whether your message gets replies or gets ignored. You'll receive a detailed report with specific fixes — delivered to your inbox within a minute.

### Subject Line

Length, clarity, personalization, and spam trigger words. Short, specific subject lines outperform clever ones.

### Opening Line

Does the first sentence earn the next? We check for prospect relevance, generic openers, and attention hooks.

### Personalization

Surface-level name drops vs. genuine prospect research. We flag merge-tag personalization that reads as templated.

### Value Proposition

Is the benefit clear and specific to the reader? Vague claims like "save time" score lower than concrete outcomes.

### Call to Action

One clear, low-friction ask outperforms multiple CTAs or aggressive calendar links. We evaluate clarity and commitment level.

### Length & Readability

Word count, sentence structure, and reading level. Cold emails that get replies are typically under 120 words with short paragraphs.

### Tone & Voice

Professional vs. casual calibration. We check for overly formal language, buzzwords, and whether the tone matches the audience.

### Spam Signals

Trigger words, excessive capitalization, too many links, and formatting patterns that email providers flag as promotional.

### Social Proof

Credibility signals like customer names, specific results, or relevant experience. Brief proof beats no proof — but too much feels like bragging.

### Overall Structure

Flow from hook to value to ask. The best cold emails follow a logical progression that makes replying feel natural, not forced.
