SUBJECT LINE: FREE SHIPPING + 50% OFF EVERYTHING — ACT NOW!!! EMAIL TYPE: Promotional flash sale — drive purchases in 24 hours AUDIENCE: Existing customers, purchased once in last 6 months SENDER: Online clothing brand, mid-market price point OVERALL SUBJECT LINE SCORE ████░░░░░░░░░░░░░░░░ Score: 22/100 Status: INBOX DEAD SECTION SCORES (each out of 20) Open Rate Potential: ████░░░░░░░░░░░░░░░░ 4/20 — Discount claims at this scale read as desperation, not value. Spam and Deliverability Risk: ░░░░░░░░░░░░░░░░░░░░ 0/20 — Multiple hard spam triggers in a single subject line. Clarity and Relevance: ████████████░░░░░░░░ 12/20 — The offer is clear, but clarity cannot rescue a subject heading to spam. Psychological Trigger: ██████░░░░░░░░░░░░░░ 6/20 — Urgency attempted but undermined by spam formatting. Preview Text Alignment: ░░░░░░░░░░░░░░░░░░░░ 0/20 — All caps and triple exclamation marks trigger mobile preview suppression in Gmail. SPAM RISK FLAGS - "FREE" in all caps — one of the highest-weighted spam trigger words in major filters - "ACT NOW" — classic spam trigger phrase - All-caps formatting throughout — flagged by spam filters and ignored by readers - Triple exclamation marks — strong spam signal - "50% OFF EVERYTHING" — discount language combined with urgency is a compound spam risk Total risk level: Critical. This subject line is likely to be filtered before it reaches the inbox. CRITICAL ISSUES (Fix These First) Issue 1: ALL-CAPS AND TRIPLE PUNCTUATION GUARANTEE SPAM FOLDER Problem: All-caps text and multiple exclamation marks are among the clearest spam signals recognised by Gmail, Outlook, and Apple Mail filters. This subject line would fail a basic spam check before a human ever reads it. Fix: Remove all caps entirely. Use sentence case. Replace "ACT NOW!!!" with a specific deadline. "Ends tonight: 50% off your next order" passes filters and creates real urgency. Impact: High Issue 2: THREE SPAM TRIGGERS IN ONE SUBJECT LINE Problem: FREE, ACT NOW, and all-caps discounting combine to create a compound spam signal. Most filters assign a score to each trigger — this subject line would score critically high. Fix: Choose one value signal and lead with specificity. "Your 50% off code expires at midnight" communicates the same offer with zero spam risk. Impact: High SUBJECT LINE REWRITE LAB Rewrite 1 — Specific Deadline (38 chars): Your 50% off expires at midnight tonight Rewrite 2 — Curiosity Plus Offer (41 chars): We rarely do this. 50% off, ends tonight. Rewrite 3 — Personal Relevance (44 chars): Since you shopped with us — 50% off today Rewrite 4 — Soft Urgency (39 chars): Last chance: half off everything we make Rewrite 5 — Conversational (46 chars): Today only — everything in your size, half price A/B TEST RECOMMENDATION Test Rewrite 1 against Rewrite 3. Rewrite 1 works for urgency-driven buyers who respond to deadlines. Rewrite 3 adds personal relevance for lapsed customers who need a reason to re-engage. Watch open rate first, then click-through rate to find which drives more revenue per send. PREVIEW TEXT SUGGESTION Pairs with Rewrite 1: "Free shipping too — no code needed, applied at checkout automatically." AUDIT COMPLETE - Email Subject Line Auditor v1.0
