Running a campaign with one code per customer usually means creating coupons by hand, one at a time. Coupon Forge lets you describe the discount once and create the whole set. Choose a prefix and a code length, pick percent off, a fixed amount or free shipping for store products, bookings or event tickets, set a minimum order subtotal, usage limits and dates, and create up to 10,000 unique codes. Codes skip look-alike characters such as 0, O, 1 and I, so customers can type them without mistakes.
Every set appears in a list with the number of codes and how many were used. Export a set to CSV to send to your email tool or print on cards, or delete the whole set when the campaign ends. If you already have codes from another source, paste or upload a CSV and the app creates them as coupons with the discount you choose.
The app only works with your site's coupons. It runs inside your dashboard, has no outside servers and keeps no copy of your codes.
