Email Spam Trigger Checker

Spam filters look for suspicious patterns such as excessive use of capital letters, multiple exclamation marks, spam trigger words (like "free", "act now", "limited offer"), too many links, missing text-to-image ratio, and deceptive subject lines. They also analyze your sending reputation and infrastructure.

Use a clear, honest subject line. Limit images and include enough text. Avoid spammy words and excessive punctuation. Ensure you have proper unsubscribe links. Send emails from a reputable domain with SPF, DKIM, and DMARC configured. Keep your email list clean and engaged.

A score below 2.5 usually means the email is very safe. Scores between 2.5 and 5 indicate some risks and should be reviewed. Anything above 5 has a high chance of landing in spam. Always aim for as low a score as possible, preferably under 3.

Words like "free", "cash", "bonus", "buy now", "click here", "limited time", "urgent", "act immediately", "winner", "guaranteed", and "no obligation" are frequently flagged. Overuse of ALL CAPS and multiple exclamation marks also raise red flags.

Yes, emails with a high image-to-text ratio are often marked as spam. Spammers use images to hide trigger words, so filters penalize emails that contain mostly images with little readable text. Always maintain a balance of at least 60% text.

The subject line is the first thing spam filters see. Misleading, all-caps, or overly promotional subject lines can send your email straight to spam. Keep it concise, relevant, and free of deceptive claims.
