If you do not have an existing website or your web-hosting provider does not meet the requirements listed above you will want to check out ListMessenger.net. This service provides you with a full copy of ListMessenger Pro running in the cloud, and starts at $149 per year.
If you are just starting out and are unsure of which version of ListMessenger to use, then we recommend starting with ListMessenger Light. It's free, and takes as little as 10 minutes to install. If you like it, then upgrading to ListMessenger Pro later is painless.
If you have any questions about ListMessenger that are not already answered on this page, please feel free to post your question in the Pre-Sales Questions section of the public forum.
