A merchant wants to allow customers to subscribe to alerts about new products and promotions.

According to the Adobe Commerce Merchant Documentation, you can use RSS feeds to provide customers with updates on new products, price changes, coupons, sales, or any other store activity that you want to share. Customers can subscribe to RSS feeds using their preferred RSS reader or email client.
