WooCommerce Coming Soon Product With Countdown lets you enable coming soon mode for the products (including variable products) with the time to launch them. Products will be automatically launched at that time and will show a countdown timer until that time is overs.
It removes the “ add to cart” button from the product when that product is in coming soon mode, and also lets you enable email subscriptions for each product individually.
An email will be sent automatically to all subscribers of that product when that product will be available to purchase. You can also customize email Subject and Contents for each product and can use HTML in Email Contents.
You can also customize Countdown Clock colors, and it has the ability to hide/show price and tabs when the product is incoming soon mode. The short description can also be customized for the coming soon products.
