Segment the unengaged
Dynamic segments surface contacts with no opens or clicks over a window, so you can target exactly who has gone cold.

Use caseWin back inactive contacts — and protect deliverability
Every list accumulates contacts who have gone quiet. Keep mailing them and engagement metrics sag and sender reputation slips; ignore them and you lose contacts you could have recovered.
A re-engagement program tries to win them back, then cleanly retires the ones who stay cold — which keeps your list healthy and your mail in the inbox.
How Zeluto does it
Run a win-back journey
An automated sequence — a we-miss-you, an offer, a last-call — gives quiet contacts a reason to come back.
Prune to protect reputation
Contacts who stay cold get suppressed automatically, so unengaged addresses stop dragging down deliverability.
What you can build
No engagement in 90 days → win-back series → still cold after the last email → auto-suppress. Your list stays engaged and your sender reputation stays strong.
