Sending Email Newsletter

[cat_mother_]

I have about 100 people who have signed up to recieve a monthly email-newsletter. (I'm NOT trying to send spam!!)

I am planning on writing a Perl script that loops through the list of emails that I have, and for each email address sends out the email newsletter. This way people will not have access to other email addresses on the list.

Is this an appropriate way to go about this? How is this normally done? (This is my first time sending out an email like this) I know that some people use web-based services the do the sending for you, but I am curious about how to go about this if I do not use such a service.

Thanks!!
