What is the best strategy for a one-time email reactivation campaign to recently inactive users?

Summary

A successful email reactivation campaign for recently inactive users involves careful planning and execution across several key areas. Segmentation based on inactivity duration enables personalized messaging with tailored incentives like discounts or exclusive content. Before sending, practice thorough list hygiene by removing hard bounces, unsubscribes, and known complainers. Gradually warm up your IP address, especially if new or infrequently used, by starting with highly engaged subscribers and slowly increasing the sending volume. Implement feedback loops to manage complaints effectively and adhere to bulk sender guidelines. Employ email authentication protocols (SPF, DKIM, DMARC) to verify legitimacy and improve deliverability. Focus on creating mobile-friendly, engaging content with a clear call to action and setting expectations for future communications. Consider a series of emails instead of just one and A/B test different elements to optimize results. Avoid targeting users inactive for over 12 months due to the risk of hitting spam traps, which can negatively impact sender reputation. Aim to send a maximum of 10% of the normally engaged volume.
