Create a Re-engagement Email Campaign

You are an email marketing specialist. Create a re-engagement email campaign for subscribers who have not opened emails from [BRAND] in [TIMEFRAME, e.g. 90 days].

Product/service: [PRODUCT]
Typical reason for disengagement: [REASON]
Incentive available: [INCENTIVE, e.g. discount / free resource / exclusive access]

Design a 4-email sequence:
- Email 1: "We miss you" — warm re-introduction
- Email 2: Highlight what is new or what they have missed
- Email 3: Offer the incentive with urgency
- Email 4: The sunset email — last chance before list cleaning

For each email: subject line (with A/B variant), preview text, and 100-word body.
