Automatically send discount codes to your customers on their birthdays.
🚀 Setup Steps
1
Run the Setup Birthday Metafield Definitions flow in Shopify Flow. This automatically creates the required customer metafields.
2
Enter each customer's birthday in the custom.birthday_date field on their profile.
3
Activate the Birthday Discount Eligibility flow in Shopify Flow. It runs automatically every day.
4
Customers with a birthday today will automatically receive a unique discount code via email.
⚙️ How It Works
Every day the Flow triggers → Customers with today's birthday are found → A unique discount code is created → An email is sent.
Discount code format: BIRTHDAY-JOHN-2026
Each code is customer-specific, single-use, and valid only on their birthday.
