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
