SFTP to SMS is ideal for high volume message sending that is not time sensitive, such as promotions. The SFTP upload facility allows users to securely transfer files to a SFTP server. These files get processed and messages are dispatched to all intended recipients.

SFTP is a push only mechanism for sending messages. Incoming data such as replies and delivery statuses can be retrieved via legacy webhooks or the control panel website.
It’s not easy to implement load balancing for the SFTP protocol, so you may experience
downtime during maintenance windows.
Although extremely simple to implement, SFTP to SMS has fewer features than the REST API. This is by design.
The SFTP to SMS processes new files every 5 seconds. A faster alternative would be via our RESTful API.
Only GSM encoding/charset is supported.
Only DOS/Windows, Mac and Unix line endings are supported.
