In email marketing, a dedicated server refers to a 'sending server' that is reserved for use by one company. A dedicated server costs more to use as the expense is not shared by several users. Dedicated servers perform better and are more robust than shared servers, in part because they protect the sender's reputation. Dedicated servers also eliminate the possibility of being blacklisted or banned from major email service provider (ESP). A dedicated server also protects the senders from the actions of other users who send spam. MyNewsletterBuilder (MNB) offers dedicated serves to qualifying businesses.
