Re-engagement emails target people who've stopped opening, clicking, or buying. The subject line has to break through months of inertia and make someone care again. The best re-engagement subjects acknowledge the absence and offer a compelling reason to return.

Tips for re engagement

Acknowledge the gap: 'It's been a while — here's what you missed'

Offer an incentive: 'Come back for 20% off your next order'

Use curiosity: 'We've changed a lot since you left'

Try a breakup email: 'Should we stop emailing you?' — these have surprisingly high open rates
