We were recently asked to help a client convert more email subscribers from their website by using an automated opt in pop-up window. Ninja pop-ups provided a great solution at a reasonable price. With a little custom coding, we were able to get it to link directly to Mailchimp, and it provides the end-user with a clean, smooth experience. One note to users, if you want to have an elegant “exit” form, you need to choose the option “When mouse leaves the browser viewport” under exit settings. Overall, great plugin for the money. We gave it 4 stars!
