email-list-hygiene

To re-engage inactive email subscribers, you should run targeted campaigns offering value or asking for updated preferences before applying a sunset policy to remove non-responders, which improves overall list health.

Email deliverability drops with poor list hygiene because high bounce rates and unengaged contacts signal to email providers that your messages are unwanted, increasing the likelihood of your future campaigns being routed to spam folders.

A sunset policy in email marketing is a rule for removing chronically inactive subscribers after re-engagement efforts fail. Use it to reduce bounce rates and protect your sender reputation.

The best way to clean an email subscriber list without losing customers is to implement a graduated re-engagement strategy that attempts to win back inactive users with compelling content before finally applying a sunset policy.

You do not need specific tools to implement list hygiene practices. This guidance focuses on strategic best practices for sunset policies and re-engagement workflows that can be applied within any standard email marketing platform environment.

You should avoid removing inactive subscribers immediately if you have not yet attempted a re-engagement campaign, as some contacts may still be retrieved and converted before a formal sunset policy is applied.
