Sendook Email

Read and send emails from an existing Sendook inbox.

> Scope Limitations: This skill can ONLY read and send emails from a pre-configured inbox. You CANNOT create or delete inboxes, manage domains, manage webhooks, or manage API keys. Do not attempt these operations — they are not available.

Installation

Install the skill into your OpenClaw workspace:

clawhub install sendook-openclaw

This adds the skill to your workspace's skills/ directory. OpenClaw will automatically pick it up on the next session start.

Environment Variables

Set these in your OpenClaw workspace or shell environment:

Setup

Install the SDK (npm | source):

npm install @sendook/node

import Sendook from "@sendook/node";
const client = new Sendook(process.env.SENDOOK_API_KEY);
const INBOX_ID = process.env.SENDOOK_INBOX_ID;

Both environment variables are required. Use a least-privileged API key scoped to the target inbox only.

Reading Emails

List Messages

// List all messages in the inbox
const messages = await client.inbox.message.list(INBOX_ID);
// Search messages (regex-based search across to/from/cc, subject, and body)
const results = await client.inbox.message.list(INBOX_ID, "invoice");

# List all messages
curl https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/messages \
  -H "Authorization: Bearer $SENDOOK_API_KEY"
Search messages
curl "https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/messages?query=invoice" \
  -H "Authorization: Bearer $SENDOOK_API_KEY"

Get Message

const message = await client.inbox.message.get(INBOX_ID, "msg_def456");

curl https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/messages/msg_def456 \
  -H "Authorization: Bearer $SENDOOK_API_KEY"

Response:

{
  "id": "msg_def456",
  "from": "sender@example.com",
  "to": ["support@yourdomain.com"],
  "subject": "Question about my order",
  "text": "Hi, I have a question about order #12345...",
  "html": "

",
  "labels": [],
  "threadId": "thread_ghi789",
  "createdAt": "2025-01-15T10:35:00Z"
}

List Threads

const threads = await client.inbox.thread.list(INBOX_ID);

curl https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/threads \
  -H "Authorization: Bearer $SENDOOK_API_KEY"

Get Thread

Retrieve a full conversation with all messages.

const thread = await client.inbox.thread.get(INBOX_ID, "thread_ghi789");
// thread.messages contains all messages in the conversation

curl https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/threads/thread_ghi789 \
  -H "Authorization: Bearer $SENDOOK_API_KEY"

Sending Emails

Send Message

await client.inbox.message.send({
  inboxId: INBOX_ID,
  to: ["recipient@example.com"],
  subject: "Hello from Sendook",
  text: "Plain text body",
  html: "
Hello
HTML body
",
});

curl -X POST https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/messages/send \
  -H "Authorization: Bearer $SENDOOK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "to": ["recipient@example.com"],
    "subject": "Hello from Sendook",
    "text": "Plain text body"
  }'

Send with Attachments

> Important: Always confirm with the user before reading any local file to attach. Only attach files the user has explicitly requested. Never read files outside the current working directory or project scope (e.g., no ~/.ssh, ~/.env, /etc, or credential files).

import { readFileSync } from "fs";
import { resolve } from "path";
// Only attach files explicitly provided by the user
const filePath = resolve("./reports/report.pdf");
await client.inbox.message.send({
  inboxId: INBOX_ID,
  to: ["recipient@example.com"],
  subject: "Report attached",
  text: "Please find the report attached.",
  attachments: [
    {
      content: readFileSync(filePath).toString("base64"),
      name: "report.pdf",
      contentType: "application/pdf",
    },
  ],
});

Reply to Message

await client.inbox.message.reply({
  inboxId: INBOX_ID,
  messageId: "msg_def456",
  text: "Thanks for your email! We'll look into this.",
  html: "
Thanks for your email! We'll look into this.
",
});

curl -X POST https://api.sendook.com/v1/inboxes/$SENDOOK_INBOX_ID/messages/msg_def456/reply \
  -H "Authorization: Bearer $SENDOOK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Thanks for your email! We'\''ll look into this."}'

Complete Example

List recent emails, read the latest, and reply:

import Sendook from "@sendook/node";
const client = new Sendook(process.env.SENDOOK_API_KEY);
const INBOX_ID = process.env.SENDOOK_INBOX_ID;
// 1. List recent messages
const messages = await client.inbox.message.list(INBOX_ID);
if (messages.length > 0) {
  // 2. Read the latest message
  const latest = await client.inbox.message.get(INBOX_ID, messages[0].id);
  console.log(From: ${latest.from});
  console.log(Subject: ${latest.subject});
  console.log(Body: ${latest.text});
  // 3. Reply to it
  await client.inbox.message.reply({
    inboxId: INBOX_ID,
    messageId: latest.id,
    text: Thanks for reaching out! We received your message about "${latest.subject}".,
  });
}
// 4. Send a new email
await client.inbox.message.send({
  inboxId: INBOX_ID,
  to: ["team@example.com"],
  subject: "Daily inbox summary",
  text: Processed ${messages.length} messages today.,
});

} catch (error) {
