I use it for 5 years now for various projects.
For the Basic gig I will add your mailchimp sign up form to your Facebook page. So you can collect email addresses from your Facebook page and you can automatically send email to your new subcriber. You must have a mailchimp account and Facebook to get starting. No modification.
