When your score needs work, one click generates AI-powered rewrite suggestions that beat your original. Stop guessing and start sending subject lines that get opened. ✨ How it works 1. Open Gmail and click Compose 2. Type your subject line — scores appear automatically as you type 3. See three color-coded ratings: Spam (0-100), Clarity (0-10), Urgency (0-10) 4. Click "Suggest rewrite" for 3 AI-generated alternatives 5. Click "Use this" to replace your subject instantly 6. Send with confidence 📋 Features - Real-time email subject line tester inside Gmail compose — no tab switching - Three-axis scoring: Spam risk, Clarity, and Urgency - AI-powered subject line rewrite suggestions that improve on your original scores - Color-coded score badges (green/yellow/red) for instant feedback - Works with Gmail light and dark mode - 50 free scores per month — no signup required - Lightweight: under 60KB, no slowdown - Privacy-first: subject text processed ephemerally, never stored 🔴 What we DON'T do - Never read your emails — only the subject line you type - Never track opens, clicks, or recipients - Never store your subject lines on our servers - Never sell your data - No account required for the free tier ⚡ Why EmailSubjectScore Pro instead of other tools? - Most subject line tools are web-based — you have to leave Gmail, copy your subject, paste it, read the result, come back. That breaks your flow every single time. - Boomerang Respondable scores subjects but costs $15/mo and doesn't suggest rewrites — you're paying for a full scheduling suite to get one feature. - AI writing tools generate text but don't score against a structured spam/clarity/urgency rubric — they can't tell you WHY a subject line is weak. - EmailSubjectScore Pro does both — score AND rewrite — inside Gmail, free to start. 💡 How is this different from web-based subject line testers? EmailSubjectScore Pro works inside Gmail — no copy-pasting to external tools like CoSchedule or SubjectLine.com. Unlike web-based analyzers, you never leave your inbox. Score + rewrite in one place, zero workflow interruption. 🎯 Built for cold emailers, sales reps, and founders If you send important outbound emails from Gmail — sales outreach, recruiting, fundraising, freelance pitches, newsletter campaigns — your subject line is the gate. EmailSubjectScore Pro is the quality check before you hit Send. ❓ Frequently asked questions Q: Is EmailSubjectScore Pro free?
