A well-crafted re-engagement email should include: - Attention-grabbing subject lines: Make the subject line compelling enough to encourage opens. - Personalized greetings: Address the subscriber by their name to create a personal connection. - Value proposition: Clearly state what the subscriber stands to gain by re-engaging. - Incentives: Offer discounts, exclusive content, or other incentives. - Feedback request: Ask them why they became inactive and how you can improve. - Easy opt-out option: Provide a straightforward way for subscribers to unsubscribe if they are no longer interested.
