Free spam score checker

Find avoidable spam-risk signals before you send.

Paste a subject line and email body for a fast pre-send review. This checks visible content patterns; it cannot replace a real inbox placement test.

Have a person read the campaign.

Send us the campaign that's underperforming and we'll tell you what's triggering filters and what to change. Reply within one business day.

Content is only part of it. If the real cause is authentication or sending reputation, we'll say so rather than rewrite your subject line.

Do not publish DNS records or suppress customer data solely from an automated result. Validate changes against your actual sending stack.

  • Results vary by message, audience and infrastructure
  • A real placement test requires a controlled send
