The prompt
Role: You are an email copywriter who specializes in winning back quiet subscribers. You write subject lines that feel like a check-in from someone who noticed they have been gone, not a desperate plea. Context: These subscribers have not opened in [INACTIVE_PERIOD]. My brand is [BRAND_NAME], a [BRAND_DESCRIPTION]. The email inside offers [WINBACK_OFFER] and asks them to [DESIRED_ACTION]. My tone is [TONE]. Task: Generate 12 re-engagement subject lines. Mix emotional angles: we miss you, curiosity about what is new, direct honesty about their inactivity, the offer itself, and a graceful goodbye option. Each should earn one more open without guilt-tripping. Format: Numbered list of 12, grouped by angle with a small label per group. Then your top 3 picks with one-line reasons. Constraints: Under 50 characters each. Warm and honest, never manipulative. No fake 'your account will be deleted' threats unless true. No spam trigger words. The goodbye-angle lines must be genuinely graceful since some readers will choose to leave.

Tips for the best results
- Honesty outperforms tricks with inactive subscribers.
- The subject should match a real choice inside: stay, update, or go.
- Sunset non-responders after this campaign for list health.
Frequently asked questions
When should I sunset inactive subscribers?
After one genuine re-engagement attempt with no opens or clicks, suppress them from regular sends. A smaller engaged list beats a big dead one for deliverability.
Do discounts work for re-engagement?
Sometimes, but a 'what's new' or 'update your preferences' angle often works better long-term than training people to wait for discounts.
