Referral Gem ‑ Refer a Friend

Referral Gem adds a word-of-mouth referral programme to your Shopify store in minutes. After every purchase, customers automatically receive a unique referral link they can share via WhatsApp, SMS, or copy. When a friend places an order using that link, Shopify discount codes are issued instantly to both the referrer and the new customer - completely automatic with no manual work required. The app includes built-in fraud detection that blocks self-referrals, duplicate IPs, and velocity abuse to protect your store. Turn your customers into brand advocates with automatic referral rewards that drive genuine word-of-mouth growth.
