How to use it

  1. 1

    Paste the exact email a prospect will receive.

  2. 2

    Review the word count, paragraph count, and longest sentences.

  3. 3

    Cut context that does not help the reader decide on a next step.

What the checker measures

The checker counts characters, words, sentences, and paragraphs locally. It uses a practical cold-email range and flags sentences over 25 words for review.

Useful guardrails

  • Use short paragraphs that make the next action easy to spot.
  • Keep the first email focused on one recipient-relevant idea.
  • Read the message on a narrow screen before sending.

Questions people ask

About this mini app

What is an ideal cold email length?

There is no fixed ideal. A concise first email is often easier to scan, but clarity and relevance matter more than hitting an exact word count.

Are short emails always better?

No. An email can be short and still vague. Include enough context for the recipient to understand why the message is relevant.

Does the checker change my email?

No. It measures locally and gives editing prompts; the content stays in your browser.
