MyCustomizer will not send you an email when an order is placed. You can see all of your orders under the Orders section of the MyCustomizer dashboard.
MyCustomizer also does not send confirmation emails to your customers when they place an order. Your ecommerce platform (i.e. Shopify or PrestaShop) takes care of that.
You can edit your Shopify order confirmation emails to display the image of your customized product and summary.
