Due to Etsy's limitations, the maximum number of tags you can add to a listing is 13, and the maximum of 10 images can be published for a single listing. 

If you have more than 10 product mockups in our Product Hub, you do not have to delete them - the first 10 will be published to your Etsy store, and the all of the mockups Gooten created will remain in the Hub.

Please note that if you already have 10 images for that particular product in your store, you can decide not to publish any of our product mockups and keep your existing images.

If you have both an Etsy and a Shopify store connected to your account, you'll still be able to publish all the product previews to your Shopify store.
