In the process of breaking down your options which newsletter software to choose, allow me to share some technical information on the software. Newsletter software can actually be divided into two different categories: the executable newsletter software and the scripted newsletter software. The first category - the executable newsletter software-is a downloadable program you install on your own computer. E-mail programs (Microsoft Outlook, Outlook Express, Eudora, etc.), Mailer programs and Newsletter Writing/Formatting programs (MS Word, Wordpad, Notepad, Ziney, etc.) fall under this category. The other category-scripted newsletter software-is normally hosted on a web server. This could be your own server or some company offering the service to the public. Autoresponders-automatically subscribe/unsubscribe clients, as well as send timed emails to the subscriber list-and text format services (e.g. online Ziney) classify under this.
