Loop log - The Tradewind Brief deliverability rescue

Synthetic reconstruction for teaching. Metric-climb with an independent grader.

/goal

Rewrite the re-engagement email until the independent spam scorer rates it >= 95/100 on the frozen rubric. The writer never edits the scorer.

Climb

• Pass 1: 41/100 - baseline draft (ALL-CAPS subject, 6 exclamation marks, image-only body, no unsubscribe)
• Pass 2: 62/100 - rewrote the subject line in sentence case; removed ALL-CAPS
• Pass 3: 78/100 - cut spam-trigger phrases ('ACT NOW', 'FREE', 'limited time') and trimmed exclamations
• Pass 4: 88/100 - added a plaintext part and fixed the link-to-text ratio
• Pass 5: 93/100 - added a one-click unsubscribe header and sent from an authenticated domain
• Pass 6: 96/100 - tuned the preheader and reduced image-heaviness below the rubric threshold

Reached 96/100 (gate 95) on pass 6. Red SPAM 41 -> green INBOX 96.
