1. Segment Your List: Start by segmenting your list to target only those subscribers who have shown low engagement over a specific period. 2. Craft a Compelling Subject Line: Your subject line should clearly convey the purpose of the email and encourage the recipient to open it. 3. Clear Call-to-Action (CTA): Include a clear and easy-to-find CTA that prompts the subscriber to reconfirm their subscription. 4. Incentivize: Offering an incentive, such as a discount or exclusive content, can motivate subscribers to reconfirm. 5. Follow-Up: Send a follow-up email to those who have not responded to the initial reconfirmation request.
