# SMS Campaigns

> Templated SMS tied to an agent's call outcomes

An SMS campaign works like a WhatsApp campaign, but sends a templated text
message keyed by whether the agent's call was answered or not — useful for
sending a callback link or summary after every attempt.

## Creating a campaign

Pick an agent and sender number, then write a message template for each call
outcome (answered vs. unanswered). Message bodies can be up to 1600
characters, and DLT sender/template IDs can be attached for DLT-registered
routes (India).

## Managing campaigns

View, update, or delete an SMS campaign at any time from the dashboard.

  Register your sender ID and templates with your SMS provider's DLT portal
  before going live — undelivered DLT-required messages fail silently on
  carrier side.
