What the Cold Email Length Checker checks

Each check is explained in plain words. Checks based on research link to the source. The rest are labeled as writing practice.

Length for a cold note

Short cold notes tend to do better. A note a little over 100 words is not an automatic fail when the extra lines are about the buyer's priority.

Short sentences

Short words and short sentences are easier to read. A note is not failed only for being over 50 words.

Easy to scan

Short paragraphs are easier to read on a phone than one big block of text.

One idea

One reason for writing is easier to answer than several. This is a writing practice, not a study result.

No pitch padding

Feature lists, product lines, and return-on-investment claims make a cold note longer without making it more useful.

Subject length

Only when you add a subject. Subjects that get opened tend to be a few plain words.

Spelling and grammar

A clean draft, with each issue quoted from your words. This is a writing practice.

Questions

How long should a cold email be?

Short enough to read in one pass: a few short sentences about their situation and one question. The checker does not fail a note only for going a little over 100 words, as long as the extra lines are about their priority.

Is shorter always better?

No. A note that is too short may not say why you are writing. Cut lines about your product first, and keep the lines about their world.

How is reading time worked out?

It is a rough estimate at an assumed pace of 200 words a minute. It is there to help you picture the reader, not a study number.

Is it free? Do you store my email?

It is free with no sign-up, and nothing you type is stored.
