Frequently asked questions
Where do birthdays come from?
A customer field you collect at signup or checkout — stored in your CRM, e-commerce platform or a Google Sheet. The daily run matches today's month and day against that field. No birthday on file means no email, so it's opt-in by nature.
How is the discount code unique?
The workflow creates a single-use code via your store's API (Shopify/WooCommerce discount create) or pulls one from a pre-generated pool. Unique codes prevent sharing and let you attribute redemptions to the birthday campaign.
