What it looks for
Whether the first line is about the reader, whether the email says why now, whether it is short enough to read in 30 seconds, whether it asks one easy question, and whether anything sounds like a promotion. The spam word checker covers the words; this covers the whole email.

Questions
What score is good?
7 and above: an email you would reply to if it reached you at the right time. Below 5, start from the rewrite.
Does it keep my email?
No. What you paste is not kept; only the answer is, for a week, so the same email gets the same answer.
Why is the rewrite so short?
Because short cold emails get read. It stays under about 110 words with one question at the end.
