The grader scores seven parts of your email with transparent rules, not a black box and not AI, so the same email always gets the same score and you can see exactly why:
- Subject line — length, curiosity and whether it reads like a broadcast.
- Opener — is the first line about them or about you.
- Relevance — signals that the message is targeted, not sprayed.
- Clarity — one idea, plain language, easy to answer.
- CTA — a single, low-friction ask instead of a demo demand.
- Brevity — can it be read in under ten seconds.
- Spam risk — flagged spam-trigger words, link count and ALL-CAPS.
You get an overall score out of 100, the flagged spam words, what already works, and the specific fixes to make.
