Sending a regular newsletters is the most effective way to keep in touch with your customers on a regular basis. You can send your newsletter directly to customers who subscribe from your site, or use a third-party service provider.
To individually manage newsletter subscriptions for each customer would be time consuming. To streamline the process, Magento Go lets you manage subscriptions of groups of selected customers by applying a single Action to multiple records. Actions can be applied to groups of selected customers or properties, which makes it easy to manage subscriptions for a large group of customers.
