We make it easy to send email newsletters to your customers, manage your subscriber lists, and track campaign performance. Unlike some of our competitors, we don't "dumb things down." We take extremely powerful tools that sophisticated marketers use (like segmentation, a/b testing, and ROI tracking), and we make them accessible to anyone. And because our platform uses an open API, it's easy to integrate internal systems (like Salesforce) and web applications (like Magento and Drupal) with our email marketing engine. That's why over 2 million users, who range from small 1-person startups to Fortune 500 corporations use MailChimp.
