To set an 'Expiry Date' of your coupon, go to:
Go to "Sites" or "Courses" depending on where you want to create the coupon.
Scroll down to the "Coupons" section and click on it.
This will take you to the Zenler coupon area. Click on "Create a Coupon".
Inside the 'Coupon' area, you have the ability to set an 'Expiry' date for your coupons:
This expiry field includes a calendar icon at the end. Clicking on this icon allows you to set a specific date for which the coupon will be valid, either in days or months.
For example, let's say I'm setting up a coupon for June 2023 and want it to expire on the 30th of that month. Once the expiry date is set, the coupon will no longer be valid, and your front-end users will not be able to receive any further discounts after the date.
