The Rebel Mail Actionable API allows you to send actionable emails from within an application. It enables you to bring actions from your application, such as booking an appointment, taking a survey or leaving a review and then push the actions into your users' inbox. Rebel provides a way to make emails interactive while not requiring plug-ins and currently supports SendGrid, Mandrill, SailThru, Mailgun ESPs and more.
