The Rebel Mail API allows you to use web functionality in emails. It enables you to integrate in-email behavior into your datastores in real time. Developers can build one email that works across all major email clients and deploy and/or report with your existing ESP. Rebel provides a way to make emails interactive while not requiring plug-ins and currently supports SendGrid, Mandrill, SailThru, Mailgun ESPs, and more.
