When you first start sending out email newsletters, it is very tempting to send them using your normal email delivery service, such as Outlook. After all, it is free and already there on your desktop. However, internet service providers frown upon mass mailing, and you will find very quickly that your email address will be blacklisted and you may be banned from sending any email. There are many legitimate email delivery services available whose costs are minimal; use one to manage your mailing list.
