MailChimp Social WordPress v1.4.7
This plugin let your public subscribe your newsletter via Facebook, Hotmail, Google, LinkedIn, VK and by just typing the email. What’s the bonus? Users do not have to confirm the email because the email is already “confirmed”. You can collect their First, Last Name and Birthday! It’s really simple to configure the plugin, I made an awesome tutorial you can find it in the tab “Help”!
