Cold email readability checker
Measure approximate word and sentence lengths to guide a manual clarity edit.
Prepare your inputs
Readability is more than a grade. This utility reports observable text counts so you can find long sentences and review whether each sentence expresses one clear idea.
Runs in this browser. Inputs are not sent by this tool or saved in browser storage. Start with the fictional example; use redacted text for reviews.
How it works
Words are whitespace-separated tokens. Sentence boundaries are approximated from periods, question marks and exclamation marks. The output includes average and longest approximate sentence length.
Worked example
Compare a long sentence joining the problem, offer and meeting request with a revision that gives each its own sentence. Then read both aloud and check whether the meaning stayed accurate.
Limits and interpretation
Abbreviations, URLs and non-English writing can make these counts imperfect. There is no reading-age score or claim that shorter copy will produce more replies.
