# Batch Sending

> Send messages to multiple recipients in a single workflow execution.

Batch sending allows a Persona to dispatch messages to a list of recipients without triggering individual workflow runs per contact.

## How it works

Pass an array of recipient objects to the send endpoint. aiConnected queues each message and processes them in parallel, respecting rate limits per channel.

```json theme={null}
{
  "recipients": [
    { "to": "user@example.com", "name": "Alice" },
    { "to": "other@example.com", "name": "Bob" }
  ],
  "template": "onboarding-welcome"
}
```

## Limits

| Channel | Max recipients per batch |
| ------- | ------------------------ |
| Email   | 1,000                    |
| SMS     | 500                      |
| Voice   | 100                      |
