How to Use the Email Spam Score Calculator
Before sending a newsletter, marketing email, or announcement, it helps to check whether the wording might trip a spam filter. Enter your email subject and body, and this tool scans for hype and urgency phrases that spam filters commonly flag, while also factoring in an all-caps subject line and excessive exclamation marks into the spam score.
The score maps to three levels — Low (safe), Medium (caution), and High (risky) — and you can see exactly which words contributed to it. Trigger phrases in the subject line carry more weight than those in the body, since real spam filters tend to scrutinize subject lines more heavily.
Keep in mind this is a lightweight wording check only. Real email spam filters also weigh sender reputation, sending history, and authentication records like SPF and DKIM, so a low score here doesn't guarantee inbox delivery. Use it as a quick reference to tighten up your copy before you hit send.
