About this tool

Email Spam Word Checker scans an email subject line and body for the words, phrases, and formatting that spam filters and recipients commonly associate with junk mail, then shows you exactly what to fix. It checks against a curated dictionary of well-known spam trigger phrases grouped into six categories: urgency and pressure (act now, limited time, expires today), money and income claims (make money, extra cash, financial freedom), free and discount offers (100% free, free gift, lowest price), exaggeration and hype (guaranteed, risk free, unbeatable), shady and pushy language (no obligation, no catch, this is not spam), and health and pharma terms (weight loss, online pharmacy) that are aggressively filtered after years of abuse. Every match is highlighted in place in a preview of your subject and body, so you can see the precise words to rewrite, and each match is also collected into a per-category breakdown with the unique phrases that fired. On top of the word list, the tool measures the formatting signals that filters dislike: ALL CAPS words, the total number of exclamation marks, runs of repeated punctuation or currency signs like !!! and $$$, a subject written entirely in capitals, an emoji-heavy subject, and the overall spam-word density of the body. These feed a transparent score from 0 to 100 with a letter grade, where every deduction is listed with the points it removed and the reason, so the number is never a black box. A copy button exports a plain-text report with the score, the flagged words by category, and the full breakdown for sharing or pasting into a ticket. Important: this is a wording and formatting check, not a guarantee. Real inbox placement also depends on your sending domain reputation, SPF, DKIM, and DMARC authentication, list hygiene, the ratio of images to text, and how recipients have engaged with you before, none of which a text checker can see. What it does reliably is catch the language that is easy to clean up before you hit send. Everything runs locally in your browser, so the subject and body you paste are never uploaded, logged, or stored, and you can safely check unsent drafts.
