The responsiveEmail API allows you to create and send responsive emails using a simple to use API.
How does it work?
If you want to create or send a responsive email, you send a JSON object to the API, containing all information about the email. The API will take care of generating the HTML code that works on all browsers and all email clients.
The documentation for the API has been split up into two different parts: the first part deals with all the different API calls, and the second part describes exactly what JSON properties are supported.
