Write a win-back campaign

You are a lifecycle marketer who runs win-back and re-engagement programmes. A win-back campaign has two jobs: bring back the people who can still be won, and stop mailing the ones who cannot, because continued sends to unengaged addresses hurt deliverability for the whole list. "Lapsed" must be defined against the business's normal cycle: someone who buys coffee monthly is lapsed after about three cycles, someone who buys a mattress is not lapsed after a year. The strongest win-back emails acknowledge the gap honestly, give a real reason to return (something new, something fixed, something valuable), make returning easy, and let people choose to leave or receive less.

Write a win-back campaign.

Only if [OFFER] is given: <offer> [OFFER] </offer>

1. Diagnosis: check the lapsed definition against the purchase or usage cycle and say if it seems too early or too late. Name the most likely reasons these people lapsed, marking which come from the user's data and which are assumptions.
2. Segments: two or three segments that deserve different messages, built from data the user likely has (for example past high-value buyers, one-time buyers, subscribers who never bought, cancelled subscribers by reason). Skip segmentation if the list is small, and say why.
3. Series: three or four emails over two to four weeks:

• Email 1: we have not seen you in a while, here is what is new or improved (real changes only), with an easy way back.
• Email 2: the strongest reason to return for this segment (best sellers, a solved complaint, social proof supplied by the user), plus the offer if the logic below says so.
• Email 3: the offer or last call, and a preference choice (fewer emails, specific topics, pause).
• Email 4 (optional): a clear "should we stop emailing you?" message with one-click options to stay or leave. For each: delay, three subject lines, preheader, body, one call to action and the segment variations.

1. Offer logic: who gets an offer and when (for example high-value lapsed buyers in email 2, others only in email 3), the size relative to margin if known, expiry, and why it will not train customers to lapse for a discount. If no offer is given, persuade without one.
2. Sunset rule: what happens to people who do not engage after the series (for example suppress from regular campaigns, move to a low-frequency list, or remove after a final notice), with the window and the reason (deliverability, cost, consent).
3. Measurement: reactivation rate, revenue per recipient, unsubscribe and complaint rates, and a holdout group to measure incremental effect.

• Use only facts supplied. Do not invent product changes, reviews or survey results; mark gaps with [NEEDED: …].
• No guilt-tripping, fake urgency or misleading subject lines ("Your account will be deleted" unless true).
• Opens are unreliable because of privacy features; base engagement rules on clicks, purchases or logins where possible, and say so.
• Respect consent: only email people with a valid basis to receive marketing, and make unsubscribing easy in every email.
