Back-in-Stock Notification Email

Create a back-in-stock notification email:

Brand name: [YOUR BRAND NAME]
Product name: [RESTOCKED PRODUCT NAME]
Product price: [PRICE]
Was previously sold out for: [DURATION OUT OF STOCK]
Limited quantity: [YES/NO - IF YES, HOW MANY UNITS]
Special offer for waitlist: [EXCLUSIVE DISCOUNT/EARLY ACCESS WINDOW/NONE]
Brand tone: [EXCITED/PROFESSIONAL/CASUAL/URGENT]

Create the following:


  Primary back-in-stock email:
    
      Subject line that immediately communicates availability
      Preview text reinforcing urgency
      Opening line acknowledging they waited
      Product details with image placeholder
      Stock scarcity messaging if limited quantity
      Any waitlist-exclusive offer
      Bold, clear CTA to shop now
      Reminder of why this product is popular (brief social proof)
    
  
  24-hour follow-up (for non-openers):
    
      Different subject line approach
      Shorter copy focused purely on urgency
      Stock update if applicable (e.g., “only X left”)
      Single clear CTA
    
  


Keep the primary email under 120 words.
Use scarcity honestly. Do not fabricate low stock numbers.
Include a suggestion for the signup form copy that captures waitlist emails on the product page.

Before sending, use ShopifyQL to pull the live inventory level for [RESTOCKED PRODUCT NAME] and confirm it is actually back in stock (quantity greater than 0).
Then build the automation in Shopify Flow:

  Trigger: inventory quantity changed for the specific product/variant.
  Condition: inventory quantity crosses from 0 to greater than 0.
  Action: send the primary back-in-stock email via Shopify Email/Messaging to the waitlist segment, followed by the 24-hour follow-up action if it goes unopened.
Create the waitlist as a customer segment (customers who requested notification for this product) so the Flow action can target it directly.
