Send a draft email campaign now or schedule it for a day and time.

Privy MCP tools: https://cotlet.dev/docs/mcp/privy.md

MCP tool: `privy_write → send_email_campaign`

Access: write. Confirm: waits for the user's OK before it runs.

Returns the campaign status, scheduled when send_at is set. With recipient_timezone on, delivery spreads over about 24 hours, and contacts with no known time zone get it at the chosen time in your business time zone. The audience is fixed when you approve, and Privy may send a scheduled email a couple of minutes early. Sent emails cannot be recalled. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `campaign_id` | string | yes | Draft campaign (id from list_campaigns) |
| `send_at` | string | no | ISO 8601 time in your business time zone. Leave out to send now |
| `recipient_timezone` | boolean | no | Send in recipient's timezone |
