SMTP or API?
SMTP stands for Simple Message Transfer Protocol, and is the protocol used for electronic mail transmission. SMTP is the process by which emails are sent from recipient to server and server to server.
API stands for Application Programming Interface, and it simply defines a method by which different applications, platforms and software can communicate with each other. The outMail API allows you to send email messages via HTTP POST using RESTful JSON objects.
All messages sent via the outMail API are authenicated with a valid api_key. API keys are setup in the outMail management portal. You can have more than one api_key for a single service making it easier to control, manage and monitor your deployed applications.
