What a content spam score can and can't tell you
Spam filters weigh hundreds of signals. Roughly, they split into two groups: content (the words, formatting and links in your email) and infrastructure (your sending domain's authentication, reputation and how people engage with you). This tool covers the first group — the part you can fix by editing the email. It can't see your domain records or reputation, so a clean score here means "no obvious content red flags," not "guaranteed inbox."
The content red flags it looks for
- Trigger words — free, guarantee, act now, winner, cash and friends, especially stacked together.
- ALL CAPS — shouty words and subjects read as spam to filters and people alike.
- Punctuation — multiple exclamation marks, rows of dollar signs, excessive symbols.
- Link balance — a wall of links with little text, or naked shortened URLs.
Frequently asked questions
What words trigger spam filters?
Free, guarantee, act now, winner, cash, risk-free, 100% — worse with capitals and exclamation marks. Treat as warnings.
Does a good score guarantee the inbox?
No — content is only half the picture. Authentication, reputation and list quality matter too.
How do I check SPF, DKIM and DMARC?
They're DNS records needing a server-side lookup; a checker is on our roadmap. Your platform's setup area usually shows their status.
