Does anybody have a technical solution for the following web service?

I want to have something looks like the following: It is similar to a mailing-list, except that only me, as the administrator can send out mass-emails to the subscribers, i.e. it is a one way communication. The recipients are passive receivers. When the subscribers subscribe to the mailing-list, they will enter some of their personal information. Among the personal information are some key words. These keywords are used for my search. When I send out some emails, I will first search relevant keywords, and send out emails only to those selected recipients...How do I do this? What kind of technical solutions are available to me? I am mostly looking for some existing tools and hopefully the solutions are simple to use -- because I am a green hand and have not been doing web-hosting stuff before. Basically, I have no idea about how to set up a server, etc. So I am hoping that there are easy and existing solutions that can help me. Hopefully they are free. I can give up the search part.

Well, I'd try signing up with "FreeForums.org". As administrator you would have the ability to send mass E-Mails to everyone signed up at your forum. If you don't want to actually run the forum part you can just not create any forums, or possibly disable the board all together. You can easily have your members sign up and set it up to look nice with little effort thanks to many presets to choose from. Your domain would be "CUSTOM.freeforums.org", but for around $12.00 (USD) you could upgrade to "CUSTOM.org". Good luck.
