Suppression lists are used by large scale SMS marketers to manage the list of people who have opted out of receiving any offers or SMS messages from you in the future.

A suppression list is usually just a list of mobile numbers in a CSV format.

To upload your suppression list follow these steps:

  • Click on the Manage Subscribers Tab
  • Click on the Suppression List (this is the last item in the list of your mailing lists)
  • Click on the “Import Subscribers” link
  • Import your CSV file
  • Map the mobile number column with the mobile / phone field

That’s it. The list of mobile numbers you imported will now be exempt from receiving any SMS’s you send out.
