Creating Groups

Campaigns use "groups" to send one message to many contacts. You can think of groups as "cohorts" of your users/customers. There are a couple of ways that you can create a group:
Once created select your group by typing in the search dialog box.

Note: By sending bulk SMS you acknowledge that everyone on your contact list explicitly accepted communication from your phone number.
Depending on the size of your SMS group it can take a few minutes for the campaign to successfully go through.
Campaign Metrics


If your outbound messages are not being delivered, you might be hitting rate limits imposed by wireless carriers. Try splitting up your campaigns into multiple sub-groups and sending them out in stages with enough time in between each campaign. Alternatively, you can purchase multiple phone numbers and split your campaigns between them.
Refer to the documentation on rate limits and message queues for more information.
