Making unique codes for brands on Shopify
Straight onto the discount. No spreadsheets.
Pick a discount you already run. Code Bulk makes the codes and adds every one to it in Shopify, then hands them to whatever sends your campaign.
Thousands of codes in one job
Set the count, length and characters, add a prefix or suffix, and see an example before you generate. Before a job starts, Code Bulk checks your settings leave enough possible codes for it.
Works with your discounts
Shopify's own code discounts, and the code discounts apps build on Shopify Functions, Discount Kit's included.
Big jobs run in the background
Leave the page while a job runs. Previous jobs shows what each one requested, imported and failed.
Then send them anywhere
Download a CSV for any platform that takes one, send a set to Klaviyo, or make QR codes that open your store with the discount applied.
Bring your own codes
Already have codes? Upload a CSV with a Coupon column and Code Bulk adds those instead.
