Open Rates: An increase in open rates among previously inactive subscribers indicates successful re-engagement. Click-Through Rates: Higher click-through rates show that re-engaged subscribers are taking action on your emails. Conversion Rates: Monitor sales, sign-ups, or other conversions resulting from your re-engagement campaigns. Unsubscribe Rates: A low unsubscribe rate suggests that your re-engagement content is relevant and valuable to your subscribers.
