Email an invoice to a client as a PDF or a link.

AroFlo API: https://cotlet.dev/docs/api/aroflo.md

`POST https://cotlet.dev/api/v1/aroflo/invoices/{invoice_id}/email`

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

Sends the email from your AroFlo account and returns who it went to and when. The invoice is saved first, because AroFlo needs a saved invoice to email. It usually follows approve_invoice. A sent email cannot be recalled. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `invoice_id` | string | yes | Invoice ID from list_invoices. |
| `to` | string | yes | Recipient email address. |
| `format` | string | no | pdf attaches the invoice, link adds a link to view it online. Defaults to pdf. |
| `message` | string | no | Text above the invoice in the email. |
