Email marketing is still one of the best ways to drive traffic to your website. You can use this WordPress plugin to add a MailChimp subscription form below your blog, right in your articles or on other places using the widget. The Ajax technology takes care about that visitor doesn’t have to leave your website while the form data gets submitted. The idea for this plugin came up because I created a new mailing list for my website. By using the RSS-driven campaign feature from MailChimp, it’s possible to send new blog posts to my website’s subscribers.
