Currently bulk coupon code generation from your Admin area is not yet possible. Our Product Team is constantly working on improving the platform and adding new and exciting features.
However we do offer the possibility to request bulk coupon codes. This is available for higher level plans and may take up to 7-10 business days to complete after the support team receives all necessary information. More details can be found here.
If you'd like to provide feedback directly to our Product Team on this, you may do so here.
