The gateway will send the first 160 characters of the e-mail as the SMS message, but if you have enabled long messages under My Profile in the client zone, it will send the first 918 characters of the e-mail.


If you want to schedule the message for later delivery, include the date/time in the subject line in the following format:


YYYYMMDDHHMM represents the date and time the message should be sent – for example:

Subject: 202211271500

  • Note: The date and time you specify will be interpreted according to the Time Zone specified in your Client Zone profile.

To view or download your logs of sent messages just login to the Client Zone (here)  and go to “Logs”.
