The FTP API is perfect for once-off, high volume message dispatches. Ideal for promotions and other messaging that is not particularly time-sensitive, you can send 50 000 messages at a time. Particularly useful for batch processing from legacy systems. All you do is upload to our FTP server, and your messages are sent instantly. Clickatell creates a history log file in your FTP folder with the status details of all messages.
