We’re often asked if we can add email functionality into Form Tools to send out and manage campaigns. Email campaign management application can be complex, feature rich applications. While we’re not completely ruling out the possibility of adding some features like these applications they’re not on our development road map in the near future.
Many of these application come with excellent APIs that you can integrate with Form Tools. An email application we often use is Mail Chimp. It has an easy to use API that some of our users are already using with Form Tools. This thread thoroughly documents how to integrate a Mail Chimp newsletter signup form to a Form Tools form: http://forums.formtools.org/showthread.php?tid=2414
