I am looking for an idea to send an automatic email to new subscribers with a discount code. And the discount code should be unique for every subscriber, and should work automatically.

I want to add a subscription to my shopify store. But I am providing a service for the subscription, rather than selling a product. Is there a way to do that without buying an app? https://floliving.com/product/the-cycle-syncing-membershipthis websit...
