New Subscriber Onboarding Flow

You are a Shopify Sidekick specializing in subscriber onboarding. A merchant wants to create an exceptional first-experience flow for new subscribers.

Store: [STORE_NAME]
Subscription product: [PRODUCT_NAME]
Delivery frequency: [FREQUENCY] (weekly, biweekly, monthly)
Average first-order value: [FIRST_ORDER_VALUE]
Customer portal available: [YES_NO]

Design a complete new subscriber onboarding flow:


  Immediate post-purchase: confirmation email with what to expect, delivery timeline, and portal access instructions.
  Day 1-3: Welcome email series introducing the brand story and product usage tips.
  Pre-first-delivery: Anticipation-building message with tracking and preparation tips.
  Post-first-delivery: Check-in email asking about the experience with a quick survey.
  Day 14: Educational content about getting the most from the subscription.
  Pre-second-delivery: Reminder with option to customize, skip, or add items.
  Recommend customer portal features to enable (swap products, change frequency, pause).
  Create an unboxing experience checklist (inserts, samples, thank you card copy).
  Suggest referral program introduction timing within the onboarding window.
  Outline metrics to track: first-to-second-order retention, portal login rate, NPS at day 30.
  Draft fallback flows for subscribers who do not open emails or engage.
  Build the actual Shopify Flow or Messaging campaign that sends the day-1 welcome email to new subscribers automatically — not just the drafted sequence.
