Thanks to the integration with YITH WooCommerce Email Templates, you are also free to customize the emails it sends.
YITH WooCommerce Multi Vendor allows you to turn your store into a multistore where vendors manage their own product and earn a commission on every sale.
The integration with YITH Multi Vendor allows also vendors to configure their own automatic coupon rewards for their own stores.
First of all, make sure you install and activate both plugins. Then, enable Coupon email system from YITH > Multi Vendor > Modules.
Now the admin can choose which email notifications should managed by vendors too.
So, go to YITH > Coupon Email System > Vendor Settings and check the options that vendors will have to see.
As soon as at least one is enabled, the vendor will be able to see a dedicated Coupon Email System menu in his/her account and set up the coupons from there.
Please, note: to be able to configure these coupon rules, the vendor has to create at least one coupon code first.
Coupons sent by a vendor can be used only for his/her own products.
