What makes a cold email get replies
Replies come from relevance and ease. Relevance means the first line is about the reader's situation, not your company. Ease means the ask is small: a yes/no question, not a 45-minute demo. Everything else, the social proof, the feature list, the signature banner, is there to support those two things or it should go.
The analyzer scores six dimensions because each one maps to a reason people ignore cold email. Unclear emails get skimmed. Generic emails get deleted. Emails with no proof get doubted. Big asks get postponed. Long emails get saved for later, which means never. Spammy emails never arrive.
- Clarity: can the reader say what you do in one sentence?
- Personalisation: is there a line only this person could receive?
- Value proposition: is the outcome specific and believable?
- Call to action: is it one question that takes seconds to answer?
- Length: under 90 words, ask visible without scrolling?
- Spam risk: any trigger words, capitals, links or images?
The lines that quietly kill reply rates
Some phrases are so common that readers stop at them. 'I hope this email finds you well' wastes the most valuable line in the email. 'My name is X and I work at Y' answers a question nobody asked. 'Businesses like yours' is a confession that you did not look at theirs. 'Just following up' admits the email has nothing new.
Claims without evidence are just as costly. '10x your pipeline' and 'industry-leading' cannot be checked, so the reader discounts them to zero. One concrete example (a number, a timeframe, a named outcome) is worth a paragraph of adjectives.
Weak: We help businesses like yours 10x their pipeline.
Better: One agency onboarded 12 domains and 36 mailboxes in under ten minutes last week.How to use the score
Treat the overall score as a direction, not a grade. An email scoring in the eighties is ready to test; anything in the fifties needs the top two issues fixed; below that, start from the rewrite. Fix issues in the order listed, since the first one usually explains most of the gap.
After editing, run the new version through the analyzer again and through the spam word checker. Then send it from a warmed-up domain with SPF, DKIM and DMARC in place. InboxOne sets those records automatically when it provisions a mailbox, so copy improvements actually reach the inbox.
- Fix the subject line first; it decides whether the body is read.
- Cut the opener to the reader's problem and the ask.
- Replace every claim with one example.
- Re-score, then A/B test the old and new version on a split list.
