Most mailing list houses charge you based upon the volume of mail you send. As your subscriber list grows, so does your monthly bill!
We don't think you should be penalized because your business is growing! All the features of a true mailing list application are yours for a one time fee, which covers the cost of installation and setup. After that, you may send email to thousands of subscribers without ever having to pay another cent towards your electronic mailings.
We will install Mailing List Pro on your server (Linux, FreeBSD or Unix derivative) so you don't need to host with us to take advantage of Mailing List Pro. If you do not host with us, there may be an additional cost to install Mailing List Pro on your server, however.
