What it actually looks at
Two very different kinds of check, and it matters that you can tell them apart.Counts, done instantly and for free
These are not judgements — they are measurements, and filters weigh them far more reliably than they weigh tone:| Check | Why it matters |
|---|---|
| HTML weight | An oversized email gets clipped by some inboxes, hiding your unsubscribe link |
| Number of links | A wall of links reads like a link farm |
| Number of distinct domains | Many destinations in one email is a classic spam shape |
| Unsubscribe link present | Its absence is the single most damaging omission |
| Postal address present | Expected by law in most places, and by filters |
| Words you repeat | The same term five times or more stops being emphasis and starts being a pattern |
An editorial read
This part is an AI analysis of how the email is written, and it returns eight signals in two families. Four are about technique — how it is written:| Signal | What it means |
|---|---|
| Clickbait subject | The subject promises more than the email delivers |
| Artificial urgency | A deadline that is not real |
| Unsupported claims | Promises nothing in the email backs up |
| Subject / content mismatch | The subject announces one thing, the body is about another |
How to read the result
The report gives a level — low, moderate, high or critical — for the campaign, and one for each of the three elements. The header takes the worst of them. When it is a single element that pulls the level up, the report names that element: you may see high at the top while the overall distribution still leans moderate, and the line tells you which of the subject, preview text or body is responsible. Every signal is a probability, and it is shown as one. You read "probable, 81%", never "your subject is clickbait". When the analysis is itself unsure, the report says so next to the result rather than hiding it. It is an estimate about how your email reads — treat it as a second opinion, not a verdict.Three signals raise the level on their own: adult content, gambling and crypto solicitation.
Those put a floor at high whatever the rest of the report says, because they affect sending
reputation beyond your own account. A phishing-like tone does not — it covers "a verification is
needed" and "an unexpected refund", which is half of all legitimate account email.
What it costs
Each run spends one analysis credit from your balance. A run that fails costs nothing — the credit goes back. If your balance is empty, the report says so instead of returning an empty result.What it cannot tell you
- It is not a spam score from a mailbox provider. Nobody outside Gmail knows what Gmail will do with a given message.
- It says nothing about your setup. A verified domain, a real sender address and a clean suppression list matter more than any wording, and they are checked elsewhere.
- It does not read your audience. Sending relevant email to people who asked for it is what keeps you out of the junk folder; no analysis of the text can compensate for the opposite.
