## Prompt

Write 3 subject-line options (under 8 words each) for a re-engagement email to users inactive for 60 days: one curiosity-driven, one benefit-driven, one urgency-driven. Label which is which.

## Response

Here are three re-engagement subject lines, each under 8 words and labeled by psychological trigger.

- **Curiosity-driven:** "Guess what changed while you were away" — Creates an information gap that compels the open.
- **Benefit-driven:** "Your saved favorites are still waiting for you" — Reminds users of existing value they already own.
- **Urgency-driven:** "Your perks expire Friday — don't lose them" — Pairs a deadline with loss aversion to drive action.

For best results, A/B test the curiosity line against the urgency line first — they typically produce the widest performance gap in win-back campaigns, and the winner reveals whether your lapsed users respond better to intrigue or stakes.
