Cold emails should read at Grade 5–6 (clear, conversational). Paste your copy to get a Flesch-Kincaid score, sentence analysis, and deliverability signals.
It analyzes your pasted email copy and returns a Flesch-Kincaid Grade Level score, word count, sentence count, average words per sentence, link count, question count, and personalization token count.
Cold emails perform best at Grade 4-6 - clear and conversational. A Grade 6.5 or below is scored as excellent, Grade 6.5-9 is flagged as slightly complex, and above Grade 9 is flagged as too complex.
The tool's ideal word count range is 50-150 words, but its own recommendation is to trim to 75-125 words, since cold emails under 125 words consistently outperform longer ones in reply rate studies.
