Description
The Campayn plugin makes it easy to add subscribe forms for your Campayn lists, or subscribe your commenters to a list.
Campayn is similar to MailChimp, Aweber and Constant Contact but has a Free for Life plan and the lowest cost paid plans. You can sign up for a free account here.
After installation the setting page will guide you through the setup and you can have your subscription form on your blog within minutes!
