Email spam test
An email spam test shows your message’s spam score before you send — from the subject and body, using SpamAssassin-style rules. Lower is better; 5.0 is the spam threshold.
Step 1–4
How it works
- 1
Paste the subject and body (or HTML).
- 2
The engine analyses content with SpamAssassin-style rules.
- 3
It catches spam words, bad text-to-image ratio, broken markup.
- 4
You get a numeric score and what to fix.
FAQ
What score is good?
Aim below 5.0. The closer to 0, the lower the content-based spam risk.
Is a content test enough?
No. Content is part of it — check SPF/DKIM/DMARC and IP reputation with the SMTP diagnostics too.
