Astra
On it. Plan locked, kicking off setup now:
**Setup (next 30 min):** Stripe coupon `FLASH30` (24h expiry), banner component on staging, email drafted to your 4,200 subscribers (sending tomorrow 10am ET — your best open window), tweet thread + LinkedIn post + Discord announcement queued.
**Tracking:** PostHog event `flash_sale_conversion` with UTM source. Baseline conversion = 2.1% from your last promo (Black Friday).
**Kill rule:** if hour-8 conversion <1.3% (60% of baseline), I'll ping you with rollback ready. If >3%, I'll suggest extending 12h.
**You'll see:** Lark pings at h4, h8, h12, h16, h20, h24 with running revenue and source breakdown.
Review the email + banner in Lark before I send tomorrow morning?
