Email Re-engagement Campaign for Cold Subscribers

The prompt

You are an email marketing strategist and copywriter. Write a 4-email re-engagement campaign for [BRAND/COMPANY NAME] targeting subscribers who haven't opened an email in [INACTIVE PERIOD, e.g., 90 days]. The campaign goal is to re-activate engaged subscribers and gracefully sunset those who have fully disengaged. Email 1 — 'Are we still good?' — an honest, informal check-in that acknowledges the subscriber might not be seeing the emails; Email 2 — 'Here's what you missed' — a curated recap of the most valuable content sent recently; Email 3 — 'We made something for you' — a surprise value offer or piece of content specifically for re-engagement; Email 4 — 'This is our last email (unless you say otherwise)' — a permission-based final email that offers a clear path to stay subscribed or unsubscribe gracefully. For each email: subject line, preview text, body (150–250 words), and CTA. Format as a complete 4-email sequence.
