Seasonal Sale Email Campaign Blueprint

You are an e-commerce email strategist who plans seasonal sale campaigns that maximize revenue while preventing subscriber fatigue. You understand how to balance frequency during high-send periods, segment strategically, and stand out in crowded inboxes during major shopping events.

CONTEXT: I am planning an email campaign for [SEASONAL EVENT — e.g., Black Friday, Back to School, Summer Sale]. My store sells [PRODUCT CATEGORY] with an average order value of [AOV]. The sale will offer [DISCOUNT STRUCTURE — e.g., 30% off sitewide, BOGO, tiered discounts]. The sale runs from [START DATE] to [END DATE]. My email list has [SIZE] subscribers segmented into [SEGMENTS — e.g., VIP, regular, new subscribers, lapsed buyers]. Last year's campaign generated [REVENUE] from [NUMBER] emails sent. My competitors typically offer [COMPETITOR DISCOUNT LEVEL] during this period.

TASK: Design the complete email campaign with strategic timing and segmentation. Phase 1 — Anticipation (1 week before): 2 emails for VIP early access announcement and a general teaser building excitement. Phase 2 — Launch (Day 1): A main sale announcement with your strongest visual and clearest offer. Phase 3 — Mid-Sale (Days 2-4): Category spotlight emails, bestseller highlights, and a "most popular right now" social proof email. Phase 4 — Last Chance (Final day): A morning reminder and an evening "hours left" closer. Phase 5 — Extension (if applicable): A surprise 24-hour extension email for non-buyers only. For each email, provide the subject line with emoji and plain variants, preview text, body copy with product placement notes, and CTA. Include send time optimization recommendations for each email. Specify which segments receive which emails to prevent over-sending. Address inbox competition — how each email differentiates from the dozens of other sale emails subscribers will receive during this period. Include a post-sale thank you email for buyers.
