# Create SMS campaign

> Create an SMS campaign with post-call message templates

Creates an SMS campaign that automatically dispatches SMS follow-up messages based on agent call outcomes (e.g. sending different text messages when a call was answered vs unanswered).

<Note>
  Only one SMS campaign is allowed per agent. To modify templates or settings, use [`PUT /sms-agent/campaigns/{id}`](/docs/api-reference/campaigns/update-sms-campaign).
