Set up your client project: lifecycle data, consent records and the brand's voice
Win-back is the campaign type that most rewards context. One Project per client means the reason codes, the consent position and the tone the brand uses with people who already bought are all in place before anyone writes a subject line, and every later run starts from them instead of from a blank chat.
What to add
Lifecycle and cadence data
Subscription intervals, average repurchase gap, cancellation survey reasons and payment-failure counts. This is what turns reason codes from a nice idea into segments the ESP can actually build, and it sharpens the dormancy trigger beyond what the public site shows.
Consent and suppression records
Which contacts opted in, when, through what, and which markets they sit in. The routing rule is only as good as the consent record behind it, and this is what lets the plan say US or EU with confidence rather than hedging.
Brand voice guide
How the client sounds to someone who has already bought from them. Win-back copy that reads like acquisition copy is the fastest way to earn a complaint, so the voice guide matters more here than in almost any other sequence.
Guide Juma with project info
Add a one-line description to each knowledge item so the right file gets used at the right moment:
- Lifecycle and cadence data: "Purchase intervals, cancellation reasons and payment failures. Use this to derive the dormancy trigger and populate the reason codes."
- Consent and suppression records: "Opt-in source, date and market per contact. Use this to route contacts between the promotional and re-permission paths."
- Brand voice guide: "How we sound to existing customers. Use this for all subject lines and body copy."

Frequently Asked Questions
What is a win-back email campaign?
A win-back campaign is a short, targeted email sequence aimed at customers or subscribers who have stopped buying, with the goal of restarting the relationship before the address is retired. It differs from a standard promotion in that the audience has already lapsed, which changes both the messaging and the risk: these addresses carry a higher chance of bounces and complaints than an engaged list.
The useful version is not one discount sent to everyone who has gone quiet. It identifies why each group lapsed, offers each the thing that actually addresses it, and controls the sending so a dormant list does not damage the domain that the rest of the programme depends on.
When should a customer be treated as dormant?
Derive it from the product's own purchase cycle rather than a round number. For a subscription or replenishment brand, find the longest standard interval, count the missed cycles that indicate a genuine lapse instead of a single skip, and add a buffer for fulfilment time. A brand whose longest cadence is four weeks reaches a meaningful signal well before 90 days.
The exclusions matter as much as the trigger. Active subscribers, recent pauses or skips, gift-only buyers, open support cases, prior complaints and hard bounces all need to be out of the audience before anything sends, or the campaign mails people it should not.
Can a win-back campaign hurt email deliverability?
Yes, and it is one of the most common ways reputable senders get into trouble. Dormant addresses are disproportionately likely to be invalid, abandoned or converted into recycled spam traps, so mailing a large silent list in one go produces a spike in bounces and complaints that mailbox providers read as a reputation signal.
The controls that prevent it are procedural. Validate and scrub the list, confirm authentication, sync suppressions, then send a seed-list placement test that has to clear the thresholds before any real cohort goes. After that, release in batches ordered most-recently-engaged first, measure bounce and complaint rates over delivered messages, and set a hard stop that pauses the programme rather than pushing through.
Is it legal to email customers who have gone quiet?
It depends on the jurisdiction and on the consent record, which is why the plan routes contacts rather than treating the list as one audience. In the US, CAN-SPAM permits commercial email to existing contacts provided the message carries truthful headers, a working unsubscribe and a physical postal address, and acts on opt-outs promptly.
In the EU and UK the position is tighter. The soft opt-in under ePrivacy and PECR covers only similar products to a prior sale, and a long period of silence weakens any argument that consent is still current, so those contacts are better served by a permission request before any promotional message. Treat this as a question for the client's counsel and their consent records: the Flow produces the routing structure and the wording, and a human signs off the legal position.
How do you know whether the campaign actually worked?
Hold out a randomised share of each segment and send them nothing. Some lapsed customers return on their own, and without a control group the campaign claims those returns as its own. Comparing the treated group against the holdout over the same window gives an incremental reactivation rate, which is the number worth reporting.
Pair it with revenue per delivered message, complaint rate and unsubscribe rate, broken out by reason code and route. That split is what tells the team which recovery path earned its place and which one to retire before the next run.
