<b>Re-engagement and sunset policies: the unsexy lever</b>
Why pruning dead subscribers lifts everything downstream.

📥 Swipe
— Sunset-flow case studies (Klaviyo / Litmus) — removing 90-day non-openers routinely lifts inbox placement for the whole list, not just the segment.
— Spamhaus on recycled spamtraps — abandoned addresses become traps; this is the mechanism that makes pruning non-optional.
— Win-back sequence teardowns — the 'is this goodbye?' flow benchmarks and why the second email beats the first.
— Engagement-segmentation guides — sending to your most-active tier first to warm a new IP, then widening.

Picked because deliverability gains from list hygiene are larger and cheaper than any subject-line tweak.

Saved you ~2 hours of sending to people who'll never open.
