Input
| Field | Type | Description |
|---|---|---|
| emails | array | Batch send: the FULL list of emails to send in one call (preferred whenever there is more than one). Each item takes the same fields as a single email. When provided, the top-level single-email fields are ignored. |
| to * | array | Recipient email addresses |
| subject * | string | Email subject line |
| body * | string | Email body in plain text or HTML |
| cc | array | CC email addresses (optional) |
| from | string | Sender email address — must match a configured provider (Gmail/Outlook/Resend). The tool selects the provider whose address matches. If both Gmail and Resend match, Gmail is preferred. Omit to use the first available provider. |
| inReplyTo | string | RFC 2822 Message-ID of the email to reply to — enables email threading for outreach follow-ups. Use the messageId returned by a previous send_email call. |
| replyTo | string | Reply-To address — where recipient replies should land. Omit unless the user asked for a specific one: the workspace default (Settings → Integrations → Resend) already routes replies to the address the agent can read. |
