Win back customers who stopped buying

Write a win-back email series for customers of {{business}} who have not bought in {{lapsed_period}}. The goal is to bring back the ones who still have a reason to buy, and to learn why the others left, without teaching everyone to wait for a discount.

What has changed since they last bought (new products, fixes, improvements):
"""
{{whats_new}}
"""

What we know about why customers drift away (survey answers, complaints, guesses marked as guesses): {{known_reasons}}
An offer we can make, if any, with its terms and end date: {{offer}}

One past email of ours, for voice:
"""
{{voice_sample}}
"""

Write three emails, sent about a week apart:
1. "We noticed": a friendly note that reminds them what they liked (with "[last product ordered]" where your email tool can fill it in) and shares one or two real things that are new, with "[link]". No discount.
2. "What happened?": a short, honest question about why they stopped, with three or four one-click answers drawn from the known reasons, plus "Something else".
3. "One last thing": the offer, if there is one, with its real terms and end date, or else a last useful reason to come back, plus a clear way to unsubscribe or email less often.

Format: for each email, a heading with its name, then two subject lines under 50 characters, a preview text, a body of 60 to 140 words, and one call to action.

For example, an opening in the form wanted: "It has been a while since your last order, so here is what has changed."

The emails should sound like a person at the business who remembers them, not a retention program. Avoid guilt ("we miss you!" in every email), fake personal notes, invented urgency, and any claim about what is new that is not in the list above. If there is no offer, do not invent one. If what is new is thin, say so and suggest sending email 2 first instead.
