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.
