Most cold emails fail before they get read. Wrong opener, vague CTA, spam trigger in the subject line - small mistakes that kill reply rates. This cold email checker scores your email across five sections and tells you exactly what to fix, based on patterns from millions of spam samples and data from 85 million cold emails.
What this cold email checker looks at
The checker scores your email across five sections, each worth 20 points. Every flag comes with a specific suggestion, not just a warning.
Checks length, word count, all-caps, spam trigger words, known outreach filter phrases, vague patterns like "quick question" or "touching base," and unicode bold characters used to fake formatting in inboxes.
Flags unfilled merge tags, walls of URLs (the most common pattern in outreach spam), weak filler openers like "I hope this email finds you well," and checks for personalisation signals that lift reply rates.
Checks word count against benchmarks from 85 million cold emails, measures your I/you ratio, flags self-centred framing, reading complexity, and rewards emails that include social proof or specific results.
Flags passive closes like "let me know your thoughts," high-commitment asks like "30-minute call" in a first email, multiple competing questions, missing signatures, and rewards a well-placed P.S.
Applies a separate rule set based on your selected industry (iGaming, SaaS, recruitment) and email type (outreach, sales, follow-up). Catches phrases that are fine in general email but red flags in your specific context.
How cold email best practices shaped the rules
The scoring rules are built from three sources: published research from Gong, Hunter, and GMass covering open rates, reply rates, and word count benchmarks across tens of millions of emails; a manual analysis of 50 real spam outreach emails to identify the phrases and patterns that appear most often; and the practical experience of running iGaming and B2B outreach campaigns.
