SMS batches are a Pro feature and require telephony. Telephony add-on charges apply. See pricing for details.
An SMS batch sends a text message to every person on your list. When someone replies, your agent carries on the conversation over two-way SMS, just as it would with a contact who texted you first.

​
Requirements

  • A phone number that is enabled and has SMS turned on
  • An agent assigned to that number: it answers every reply

​
Settings

For an SMS batch you configure:
  • Assigned phone: which of your SMS-enabled numbers sends the messages. The number’s assigned agent handles replies.
  • Message: the text sent to each recipient. You can reference recipient columns in it (for example, {{first_name}}). Outbound SMS messages are kept short to fit within a single message segment.
  • Additional context: optional batch-level context passed to the agent for every conversation.
You can also add Campaign instructions so the agent follows up with people who do not reply. See Campaign instructions.

​
Sending

Before an SMS batch starts, you confirm that every recipient consented to receive your messages, each time you run or schedule it. Texts go out only between 8 AM and 9 PM in the batch’s timezone unless you acknowledge otherwise. See Sending and scheduling. Texts from a number are paced to its carrier limit, so a large batch takes time to go out, while your agent’s replies to people are never delayed. A text is never sent twice when a send is retried.

Recipient Statuses

​
Opting Out and Back In

Recipients can opt out at any time by replying with a standard keyword such as STOP, and opt back in by texting START. Only a message that is just the keyword counts, so “stop by later” is not an opt-out, although a plain-language request to stop is recognized too. A phone opt-out covers both texts and calls. See Opt-outs.
