Getting the word out to people about your company, hobby, organization, or interests is very important and email is a great way to do that. Unfortunately, spammers also know this and constantly try to abuse any system created for easy communication. Newsletter emails can be done in more compliant ways to assure much higher delivery rates as well as custom styles to separate yours from the rest. Using a professional service is highly recommended for newsletters over email.
Professional newsletter services provide templating so you can easily place content into a consistent looking layout and statistics on email recipients, forwarded emails, unsubscribers, etc. can be gathered and reported. You should also be able to place a sign up form right on your website for guests to easily and quickly grow your mailing list.
Sending from your own server space with a software that promises delivery is not a great idea and can land your domain name on a blacklist if you're not careful. Any type of mass mail sending is watched very closely now and there are very specific and ever changing rules on how to do it right. Using a professional system to accomplish this will provide much more security and success with your newsletter initiative.
