Instead of blanket unsubscribing, consider re-engagement campaigns or segmented outreach before removal. Smart targeting can bring back valuable subscribers who aren’t truly lost. Some subscribers are still valid but simply haven’t interacted recently. They may be busy, use a secondary inbox, or have their activity hidden by privacy features like Apple Mail Privacy Protection.
You might be unsubscribing potential customers who could have been reactivated with the right messaging.
