Subject lines for dormant-but-not-churned subscribers.
Re-engagement subjects sit between winback and nurture. The recipient hasn't churned, just gone quiet. Subjects that work: reference a previous specific behavior ('You used {{product}} {{n}} times last quarter — need your brain'), seasonal cause ('It's been a winter'), or surface a specific update tied to a prior request ('We built the thing you asked for in May'). Avoid generic 'we miss you' subjects — they underperform across every audience in our scoring corpus. The 'need your brain for 10 minutes' subject pattern is particularly strong for power users; asking for help re-engages better than offering help.
