What you receive

✏️

10 Subject Line Variants

Consequence-first rewrites of your original subject — covering urgency, curiosity, outcome, question, and stakes framing.

📊

Score + Ranking

Each variant is scored and ranked by estimated open rate lift — so you know which one to A/B test first.

🔍

Original Diagnosis

A clear breakdown of why your original subject line underperforms — feature-first framing, announcement hook, missing stakes.

🎯

Recommended A/B Pair

The two variants most likely to produce a meaningful test result — picked based on framing contrast, not arbitrary choice.

📋

Preheader Variants

5 matching preheader lines — written to extend the subject line hook, not repeat it.
