To make any changes to your marketplace template, please send us an email at email@example.com with your marketplace URL, login email and the new template that you would like and we make the change for you. Since it is a new template, all listings on your marketplace will be removed after the change.
You can pick a theme for your template from the link here. Do remember that you'd have to pick a theme that the template corresponds to! For example, you should pick retail theme 1 for your retail template.
Do note that the changes will take 3-4 working days to complete for those under our freemium plans. We will try to make the changes within 48h for our paid users.
