It certainly does! The Cmail API makes it all too easy to integrate your Cmail account into another application.
Using the API you can add and remove subscribers from your lists, update their details and even create and send email campaigns.
We've put together plenty of documentation on each method, and some sample code in a variety of languages to get you started. You'll also find a quick overview on getting the required details from your own account.
So jump in and get started! Don't forget to visit our forums which have a category just for API related discussions.
