Shopify birthday discount automation.
Capped at $50 of love.

Shopify birthday discount automation drives the highest open rates of any lifecycle email, and also the longest average cart — people self-treat. Cap the percentage so the celebration doesn't cost you a quarter point of margin, and automate the trigger off the birthday field on the customer profile.

    Why Shopify birthday discount automation needs a cap

    When customers redeem a birthday code, they treat themselves. Average order value on birthday redemptions runs 1.7×–2.2× the store baseline, so an uncapped Shopify birthday discount automation quietly leaks margin to exactly the cohort that's already buying more. Capping at $50 per redemption lets the gift feel generous on a normal cart and stops the whale baskets from writing the cheque.

    02

    A 7-day window keeps the birthday discount celebratory

    The narrow redemption window protects the sentiment ('it's my birthday gift from this brand') and gives clean attribution. After day 7 the code dies and you can measure whether the automation moved the customer up the LTV curve — the kind of lifecycle signal a Shopify birthday discount app is supposed to generate in the first place.

    03

    Same Shopify anniversary discount, same automation rules

    Use Nex Discount to set up parallel rules for purchase anniversaries — 'one year ago you bought your first ___.' Same 20%/$50 cap, different trigger date. Automating the Shopify anniversary discount off the first-order timestamp keeps the math predictable across both lifecycle moments without juggling two disconnected apps.
