    Frequently Asked Questions

    An email spam score predicts how likely your message is to be flagged as spam by email providers. It evaluates subject lines, body content, HTML structure, and sending reputation.

    Our tool analyzes your content against 50+ spam triggers, including excessive punctuation, spammy words, suspicious links, poor HTML practices, and image-to-text ratio. It gives you an overall score and actionable tips.

    Common triggers include 'free', 'act now', 'limited offer', 'click here', 'buy now', '100% free', 'guaranteed', and excessive use of dollar signs. Our checker highlights these and more.

    Keep subject lines under 60 characters, avoid ALL CAPS, use a healthy text-to-image ratio, always add alt text to images, and never hide text. Our tool shows you exactly where to improve.

    No, everything runs locally in your browser for privacy. It's a content quality checker, not an inbox placement test. For full deliverability testing, use services like GlockApps or MailTester.
