Definition
Email reactivation, also called re-engagement or win-back, refers to a targeted campaign designed to restore engagement among subscribers who have become dormant. Dormant subscribers are those who have not opened or clicked any email within a defined period, typically sixty to ninety days. Reactivation campaigns give these subscribers a final opportunity to re-engage before being suppressed or removed from the active list. The dual goal is to recover some lost subscribers while cleaning the list of unresponsive contacts that harm sender reputation.
Reactivation campaigns typically achieve a ten to thirty per cent re-engagement rate, meaning that out of every one hundred dormant subscribers contacted, ten to thirty will open the reactivation email and resume active engagement. The remaining seventy to ninety per cent either remain dormant or unsubscribe. Subscribers who do not respond to the reactivation campaign should be suppressed from future sends to protect overall list health and deliverability.
Best Practices
Design reactivation campaigns around a compelling offer or message that addresses why the subscriber lost interest. Offer-based reactivation provides a discount or exclusive content to incentivise re-engagement. Curiosity-based reactivation uses subject lines that highlight new features or improvements since the subscriber left. Survey-based reactivation asks the subscriber why they stopped engaging and uses the feedback to improve future content.
Time reactivation campaigns based on your specific engagement window. Begin reactivation outreach when a subscriber has not engaged for sixty days. Send the first reactivation email at day sixty, a follow-up at day seventy-five, and a final notice at day ninety indicating that the subscriber will be removed from the list if they do not respond.
Distinguish between reactivation and re-engagement carefully. Reactivation targets subscribers who have already become dormant and stopped engaging entirely. Re-engagement targets at-risk subscribers who have declining engagement but are not yet dormant. Reactivation is a rescue mission; re-engagement is preventative maintenance.
Measure reactivation success by the percentage of dormant subscribers who resume sustained engagement, not just by those who open the reactivation email. A subscriber who opens the reactivation email but never engages again has not truly been reactivated. Track engagement for thirty days after the reactivation campaign to confirm recovery.

Frequently Asked Questions
Reactivation targets subscribers who have already become dormant and stopped engaging entirely. Re-engagement targets at-risk subscribers with declining but not yet zero engagement. Reactivation is corrective; re-engagement is preventative.
Typical reactivation rates range from ten to thirty per cent. A rate below ten per cent suggests the dormant segment includes many invalid addresses or subscribers who no longer have any interest. A rate above thirty per cent suggests the dormant window may be too short.
A reactivation campaign typically includes two to three emails sent over a four to six week period. The first email arrives at the start of the dormant period, the second a week later, and the final email before the subscriber is suppressed.
Suppress non-responders from all future active sends. They should not receive promotional, newsletter, or transactional emails. Remove them from your active list entirely at least once per year to maintain list hygiene and protect sender reputation.
Yes, sending reactivation campaigns to dormant subscribers can increase bounce rates and spam complaints if the addresses are invalid or the subscribers report the messages as spam. Always send reactivation campaigns to a separate IP or warm the dormant segment gradually.
