Hello, Adam,
1/ xstore/framework/features/search-page.php (changes in file)
6/ It is not possible to create different versions for mobile/desktop email design, unfortunately. Since you want to have smth extra we recommend you try to contact any other Email Builder plugin developers to ask if their plugin could cover all your questions or try to use the default Email design that comes from WooCommerce and customize it according to your needs.
Best Regards,
