Generate hundreds of unique codes from one pattern
Set the discount, expiry and usage limit once for the whole batch
Check every code against the ones already on your site
Find and delete expired, used-up and never-expiring coupons
Single-use codes are the whole point of a creator campaign, an insert card, or a win-back email — and making them one at a time is why most stores never run one.
Bulk Coupon Manager turns one campaign into hundreds of unique codes. Pick a pattern like SUMMER-{RAND6} or WS{SEQ}, say how many you need, set the discount, expiry and per-code usage limit once, and every code in the batch inherits it. The codes download as a CSV the moment they exist — that is the file you hand to an influencer, print on an insert, or paste into an email tool.
Codes are drawn from an alphabet with no 0/O, 1/I/L or 5/S, so nobody mistypes one off a printed card. The batch is checked against the coupons already on your site before anything is written, so a rerun never quietly reissues a code you already have.
The second half is housekeeping. See every coupon currently live, with the ones that need attention called out: expired but still switched on, used up, never used, or set to never expire. Select those in one click, back them up to CSV, and delete them.
