# AgentMail SDK

AgentMail is an API-first email platform for AI agents. Install the SDK and initialize the client.

## Installation

```bash
# TypeScript/Node
npm install agentmail

# Python
pip install agentmail
```

## Setup

```typescript
import { AgentMailClient } from "agentmail";
const client = new AgentMailClient({ apiKey: "YOUR_API_KEY" });
```

```python
from agentmail import AgentMail
client = AgentMail(api_key="YOUR_API_KEY")
```

## Inboxes

Create scalable inboxes on-demand. Each inbox has a unique email address.

```typescript
// Create inbox (auto-generated address)
const autoInbox = await client.inboxes.create();

// Create with custom username and domain
const customInbox = await client.inboxes.create({
  username: "support",
  domain: "yourdomain.com",
});

// List, get, delete
const inboxes = await client.inboxes.list();
const fetchedInbox = await client.inboxes.get("inbox@agentmail.to");
await client.inboxes.delete("inbox@agentmail.to");
```

```python
# Create inbox (auto-generated address)
inbox = client.inboxes.create()

# Create with custom username and domain
from agentmail.inboxes.types import CreateInboxRequest
inbox = client.inboxes.create(
    request=CreateInboxRequest(username="support", domain="yourdomain.com"),
)

# List, get, delete
inboxes = client.inboxes.list()
inbox = client.inboxes.get(inbox_id="inbox@agentmail.to")
client.inboxes.delete(inbox_id="inbox@agentmail.to")
```

## Messages

Always send both `text` and `html` for best deliverability.

```typescript
// Send message
await client.inboxes.messages.send("agent@agentmail.to", {
  to: "recipient@example.com",
  subject: "Hello",
  text: "Plain text version",
  html: "<p>HTML version</p>",
  labels: ["outreach"],
});

// Reply to message
await client.inboxes.messages.reply("agent@agentmail.to", "msg_123", {
  text: "Thanks for your email!",
});

// List and get messages
const messages = await client.inboxes.messages.list("agent@agentmail.to");
const message = await client.inboxes.messages.get("agent@agentmail.to", "msg_123");

// Update labels
await client.inboxes.messages.update("agent@agentmail.to", "msg_123", {
  addLabels: ["replied"],
  removeLabels: ["unreplied"],
});
```

```python
# Send message
client.inboxes.messages.send(
    inbox_id="agent@agentmail.to",
    to="recipient@example.com",
    subject="Hello",
    text="Plain text version",
    html="<p>HTML version</p>",
    labels=["outreach"]
)

# Reply to message
client.inboxes.messages.reply(
    inbox_id="agent@agentmail.to",
    message_id="msg_123",
    text="Thanks for your email!"
)

# List and get messages
messages = client.inboxes.messages.list(inbox_id="agent@agentmail.to")
message = client.inboxes.messages.get(inbox_id="agent@agentmail.to", message_id="msg_123")

# Update labels
client.inboxes.messages.update(
    inbox_id="agent@agentmail.to",
    message_id="msg_123",
    add_labels=["replied"],
