Your best acquisition target is already in your database. They just stopped opening your emails six months ago.
Every marketing database accumulates a dormant segment: people who were once interested enough to sign up, buy, or attend — and then went quiet. Most marketers either ignore them (losing the asset) or keep emailing them anyway (destroying their sender reputation). A structured reactivation campaign is a third option: a purpose-built effort to recover what is recoverable, retire what is not, and improve list health in the process.
- Reactivate 15–25% of dormant contacts with the right approach
- Improve sender reputation instead of destroying it by emailing the wrong segment
- Clean list health that makes every future campaign perform better
30-minute, no-pressure consultation — typically a reply within 24 hours.
Your database is an asset. A dormant segment is a liability you are paying to maintain.
Dormant contacts are not neutral — they actively hurt your deliverability, your open rates, and your campaign ROI. And most of the standard advice about reactivation is wrong.
You keep emailing 40,000 people who have not opened anything in 18 months
Your open rate is 12%. Your deliverability has been declining. Gmail and Outlook are watching how your list responds — and a large dormant segment that ignores your emails signals to mailbox providers that your content is not worth prioritising. Every campaign to your full list gets dinged by the engagement data from 40% who have not opened in a year.
Your "we miss you" campaign got 1.2% open rate and you called it failed
A single re-engagement email with a generic discount offer — sent to all dormant contacts at once — is not a reactivation strategy, it is a clearance sale. A properly sequenced reactivation campaign with progressive incentives, personalised messaging based on what the contact originally engaged with, and a clear sunset policy performs four to six times better.
You are not sure which of your dormant contacts are actually gone versus just waiting
Some contacts have changed email addresses. Some have left the company you sold to. Some are genuinely still interested but stopped engaging because your content became less relevant. Some are actively looking right now but you have not sent them anything worth clicking. Without segment analysis and a testing approach, you cannot tell the difference — and you cannot treat them the same way.
A reactivation strategy built on who your dormant contacts actually are
Segment, sequence, and sunset — the three-part framework that recovers the reactivatable, retires the rest, and improves your list health throughout.
Dormancy segmentation and analysis
We segment your dormant list by depth of dormancy (3 months, 6 months, 12 months, 24+ months), original engagement type (subscriber, purchaser, trial, event attendee), and last known interest. Different segments have different reactivation potential and require different approaches — a single campaign for all dormant contacts performs like an average of the worst.
Win-back sequence design
A 3–5 step reactivation sequence for each primary segment: an acknowledgement of the gap, content matched to their original interest, a progressively stronger incentive, and a direct re-engagement ask. Each step includes a meaningful subject line, personalised body copy, and a clear action. Not "we miss you" — but a specific reason to return.
Re-engagement offer strategy
The right offer depends on the segment and the original relationship. A former customer needs a different incentive than a subscriber who never bought. We design offers that reactivate the relationship — access to a new resource, a relevant update, a content upgrade, or a direct conversation — not just discounts that attract low-quality re-engagement.
Sender reputation management
Reactivation campaigns need careful send management to avoid amplifying deliverability damage. We use domain warming, send volume staging, and engagement-based list management to ensure the reactivation effort improves your sender score — not damages it further. The unhealthy segment is managed separately from your main list throughout.
Sunset policy design
A structured sunset policy — the point at which an unresponsive contact is moved to a suppression list — protects your deliverability and your marketing investment going forward. We design a sustainable policy with your list health in mind, including re-permission mechanics for contacts in regulated industries where explicit consent is required.
Reactivation analytics and list health reporting
Conversion tracking through the reactivation funnel: open rate by segment, click rate by sequence step, reactivation rate, and suppression volume. A post-campaign report with the list health impact measured — deliverability improvement, open rate improvement, and the financial value of reactivated contacts expressed in pipeline or revenue.

- 1
Segment and diagnose
We analyse your full dormant segment — how deep the dormancy is, what the contacts originally engaged with, and what proportion are realistically reactivatable. This shapes the number of campaigns, the incentive strategy, and the expected recovery rate before we write a single email.
- 2
Design the sequences
We write the email sequences for each segment: subject lines, body copy, calls to action, and the logic for what happens if someone opens but does not click, or clicks but does not convert. Every step has a hypothesis about what it will move.
- 3
Configure and warm
We configure the campaign in your email platform, set up the send staging to protect deliverability, and warm the domain if needed. The campaign runs in phases — starting with the most recently dormant contacts who have the highest probability of reactivation before moving to deeper dormancy tiers.

Optimise, sunset, and report
After the first sequence run, we review performance by segment and optimise messaging for subsequent waves. Unresponsive contacts are progressively moved to the suppression list. The final report documents the reactivation rate, list health improvement, and the financial value of recovered contacts.
A healthier list that performs better — and contacts you thought were lost, recovered
The deliverability improvement alone often justifies the investment — and the recovered revenue makes it a clear positive ROI.
