permission based email

Hi guys,

i am wondering is it possible to use php to develop a permission based email system ?? i was told this kind of online system only can be done by using java with js..

can somebody give me an idea where i can get some reference how php can send bulk htm email like a permission based email ?? tracking the activities might not be so important in my case.. i just want my clients get our newsletter every month.

i have tried to use while loop to send out an email to all people from my database but the output is totally different from how it suppose to look like. .. the layout structure become different and the color that suppose to be one color turn to another.. this kinda weird for me coz i do follow and use all the headers that i was asked to use.. but it was not working

i have about 300 people from my mailing list and i wish to send them newsletter without paying for this service.. i really hope you guys could assist me on this.. please advise how can i send html emails to multiple people correctly.

thanks

You should be able to develop such a system in PHP that'll scale to accommodate a list of 300 people. Or better yet, go to sourceforge.net and see what others have developed along the same lines. There are several fairly robust emailer systems written in perl and python. As for colors, it's probably a code error.
