Free tools for preparing, validating, and scaling outbound email safely.
Preflight your copy for content-risk signals.
Paste subject and body (optional HTML) for a transparent local preflight — not an official Gmail or Outlook spam score.
Empty
Paste subject and body to run a local content-risk preflight before you send.
Why this matters
Content preflight is part of safer outbound.
Content-risk preflight
This tool scans subject, body, and optional HTML for common spam triggers — capitalization, links, hidden content, and high-risk phrases.
Not a mailbox score
Providers also weigh sender reputation, authentication, engagement, and private filtering. A low score here does not guarantee inbox placement.
Analyzed locally
Your copy never leaves the browser. Nothing is uploaded or sent to analytics — only that you ran the tool.

Straight answers
Spam Content Checker FAQ
Is this a SpamAssassin score?+−
No. It is a deterministic, transparent checklist tuned for outbound copy — not a provider spam filter or third-party scoring service.
Should I paste HTML?+−
Optional. HTML helps detect hidden text, image-heavy layouts, and missing unsubscribe mentions — common content-risk signals.
What if I get a high score?+−
Review the flagged issues, rewrite risky phrases, and test again. Also verify SPF, DKIM, and DMARC before scaling sends.
