This post is a two part post.
Part one - I would like to set up multiple mailing list (newsletter) on my site using wordpress, does anyone have any experience with a plugin that will allow this and would recommend it?
Part two - I would like to build a gravity form that will not only allow a client to submit data to me, but also add them to a newsletter plugin for Wordpress.
I am trying to keep everything local on the site, I would rather pay for a plugin then a service. So any help or advice would be greatly appreciated.
