How can I send unique discount codes via email after a product purchase?

Shopify Discussion

I have some products (3 t-shirts) and buying one gives the user the ability to have $25/$50/$75 off specific products based on which T-shirt they purchase.

I want it to function as follows:

  • When user purchases T-shirt, they get emailed a unique code

  • One of the T-shirts has 500 stock, once it is sold out, it will not be restocked

  • So that T-shirt needs to have 500 unique codes which give $25 off specific products from a collection

  • Code would expire after one year

  • Code would have to be unique (ie to stop people giving the code to other people)

What would be the easiest way to do this?

I’ve had a look at:

  • couponcarrier

  • klaviyo

  • Selly united

  • retainful

and not had any luck

Needing them to be emailed, unique, have expiry, collection conditions, max codes, and tier pricing can mean needing to hobble together a bespoke process with different apps.

If no discounts apps are capable of this combinations of needs you may need a custom app , or a more indepth app like usemechanic to put that business logic into an automation script.

Realistically you may just need to simplify this scheme or you can be burning a lot of time on an overcomplicated scheme. Unless you’ve done a sale like in a different medium than shopify with proven revenue generation, simplify. Or have time&budget to experiment.

If a pricing scheme is complicated to setup that’s a strong indication it could confuse customers and clog support.

Point of order: one use customer specific codes, otherwise one use and sharable

Pregenerating Discount Codes

Apps like matrixify have a process to create discounts in bulk using spreadsheets

Brute force

A grunt way if there is only supposed to be ~500 unique codes for an equivalent item stock , create all the single-use discount-codes and put them into order notification templates with logic to dole out 1 discount per eligible order based on stock left or order-number,etc. Add some padding to that maximum for orders or you could end up in a spot where some percentage of customers at the end of the line don’t get one either from software race-conditions or orders with multiple quantities.

Shopify Plus

If your on shopify Plus use checkout scripts and Flow to tag customers

Alternative

This could be broken down to purchasing just gives access to a different set of products priced lower and then it’s simply inventory sync’ing and something like a soft membership management with tags. Tier pricing with or without a tier pricing app. This method ties the discount to the purchasing account and should be tested to see how it behaves in reporting.
