mailing list manager (for street adresses)

You'll nedd to provide some clarification on what you're trying to do. What is the purpose of your mailng list? To send out an email newsletter? To manage a subscription service of some sort? Sales letters?

There are a multitude of services and software out there to choose from. The best ones are those that serve your particular niche. It's difficult to recommend something without knowing more.

Hope that helps.
