Mail to 8 Viral List Building Services At Once With List Mailer GT
I just finished up a new product -- free and commercial versions are available. It's called List Mailer GT, and it will send your messages to eight "viral list building" services at once, with "personalization" done correctly for each one without your having to create different versions of your message.
I originally created this script for my own use to streamline the process of sending messages to three services that I was a member of. Once I had that working, adding support for additional services was the obvious next step.
The commercial version, List Mailer GT Pro, adds a few extra features like support for tracking code in your links so that you can tell how much response you're getting from each service, and more.
