By connecting REIvolution to your Mailchimp account you build your email lists in Mailchimp automatically from Podio. You can enroll buyers in your Mailchimp lists, so you can later send email campaigns to them.
You can add a buyer to a Mailchimp list, and then later change the list or remove him at a click of a button.
