MailChimp is email marketing made easy. The platform is powerful but not intimidating, so that it can be run by business people with a range of skill sets. By integrating MailChimp with Maximizer you can eliminate the work of constantly uploading lists. The contacts and the fields you have entered on these contacts in the CRM are synchronized up to MailChimp. From there you can do marketing to any sub-set of your list based on these familiar fields. An added benefit is that sales people can see the marketing click through and open history that marketing has generated right inside of Maximizer.
