A re-engagement flow should make it easy for an inactive subscriber to choose what happens next. A discount sequence sent repeatedly to people who have stopped responding is not a preference strategy.
Define inactivity for the message you plan to send
Use a meaningful signal that is available and appropriate: no clicks or replies for a stated period, no recent purchase, or a subscriber’s own preference. Do not rely on opens alone. Consider whether the person could still be active but use privacy settings, another device, or a different channel.
Use one short message to offer clear choices: keep receiving the current topic, reduce frequency, change topics, or unsubscribe. Explain what each choice means and make the unsubscribe path visible. If the user takes no action, follow the suppression or sunset rule the business approved; do not keep extending the flow indefinitely.
Example sequence
- Message 1: “Still want monthly campaign notes?” State what the reader will receive and provide preference options.
- Message 2, only if allowed by policy: A brief final reminder after a suitable interval; repeat the choices once.
- After the cutoff: Suppress from promotional sends while preserving only records needed to honor the choice and measure the process.
Do not threaten loss, obscure the opt-out, or imply that an expired offer is a personal consequence.
Evaluate whether the flow is respectful
Track preference changes, unsubscribes, spam complaints, and subsequent useful actions by the eligible cohort. Compare the re-engaged group with its own baseline and label selection effects; do not claim the email caused later purchases without a suitable comparison. Review the flow when cadence or consent practices change.
Optional AI-assisted work brief — Respectful sunset decision
Design a re-engagement test with a clear eligible population, one honest reason to respond, an easy preference or unsubscribe route, and an automatic sunset rule. Exclude recent purchasers, active support cases, and addresses with delivery risk. Define success as a meaningful renewed preference or action, not an open pixel alone. Keep the final message concise and do not create false urgency.
Worked example — Use a sunset branch, not endless reminders
After a clear re-engagement message and a reasonable response window, suppress inactive recipients from routine marketing unless they re-engage or consent under the applicable rules supports another route. Keep transactional and service communications governed separately. A sunset policy protects deliverability and the reader’s choice; it is not a trick to make an old list appear larger.
