A list of old customers is not dead:
it is just unactivated
A list that has not been messaged in a year still has value, but a single blast to all of it at once usually wastes most of that value. We segment first, then build a reactivation push sized to what each segment actually needs to hear.
Where the money leaks today
Customer lists accumulate dormant contacts over time, people who bought once years ago, subscribed and never engaged, or simply stopped responding for reasons the business never investigated, and the common instinct is either to ignore that segment entirely or to blast it once a year with a generic discount hoping something sticks.
Both approaches waste the list’s real value. Ignoring it means genuine, reachable customers who would respond to the right message never get one. Blasting it without segmentation means the same offer goes to someone who lapsed a month ago and someone who lapsed three years ago, when those two groups need very different approaches, and often means sending to contacts who are no longer valid at all, which drags down deliverability for the whole send.
The deliverability risk is the part most reactivation pushes ignore until it is too late: sending a large volume of email to a list that has not been engaged with in a long time, much of it now invalid or inactive, can damage sender reputation for every email sent after, not just the reactivation campaign itself.
What we do
We start with a list health check before sending anything: which contacts are still valid, which show any engagement history worth building on, and which represent real deliverability risk if messaged at full volume. This step alone often removes a significant share of a dormant list that would otherwise have been wasted send volume.
We segment the remaining, reachable contacts by how recently they lapsed, their past value, and any signal about why they stopped engaging, and build a reactivation sequence per segment rather than one message to everyone. A customer who lapsed a month ago gets a different approach than one who lapsed years ago and may need a stronger reason to look again.
Any incentive used in the push is capped and agreed with you in advance, sized against your margin so the campaign’s cost does not exceed the revenue it recovers, and we build a sunset policy for contacts who still do not respond after the push, since a list that keeps every unengaged contact forever is a deliverability liability masquerading as an asset.
What we need from you
Export access to your dormant list with whatever purchase or engagement history exists, and your rules on acceptable incentive depth, since this determines how aggressive the reactivation offer can be without costing more than it recovers.
How we measure
Reactivation rate and revenue by segment, and the condition of the list at the end of the push: how many contacts responded and are worth keeping active, how many should be sunset to protect future deliverability. The real success measure is a smaller, genuinely engaged list, not a large list that still mostly ignores you.

FAQ
How much does list reactivation cost?
From $800 for the health check, segmentation and a full reactivation sequence delivered as a one-time push. Ongoing win-back as new customers lapse is a separate, recurring service.
How long does it take?
2 to 3 weeks from list access to a completed push, including the health check that should happen before any messages go out to protect deliverability.
What budget do we need?
No ad spend is required, this runs on your own list. Any reactivation incentive is the main variable cost, sized to your margin and agreed before launch.
What do we need from you?
Export access to the dormant list with whatever purchase history exists, and your rules on acceptable incentive depth, since a reactivation push without discount discipline can cost more than the reactivated revenue is worth.
How do you report on performance?
Reactivation rate and revenue by segment, plus the final state of the list: how many contacts responded, how many should be sunset, so you end with a smaller but genuinely usable list rather than a larger dead one.
