AgentMail SDK

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

Installation

# TypeScript/Node
npm install agentmail

# Python
pip install agentmail

Setup

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

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

Inboxes

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

// 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("[email protected]");
await client.inboxes.delete("[email protected]");

# 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="[email protected]")
client.inboxes.delete(inbox_id="[email protected]")

Messages

Always send both text and html for best deliverability.

// Send message
await client.inboxes.messages.send("[email protected]", {
  to: "[email protected]",
  subject: "Hello",
  text: "Plain text version",
  html: "<p>HTML version</p>",
  labels: ["outreach"],
});

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

// List and get messages
const messages = await client.inboxes.messages.list("[email protected]");
const message = await client.inboxes.messages.get("[email protected]", "msg_123");

// Update labels
await client.inboxes.messages.update("[email protected]", "msg_123", {
  addLabels: ["replied"],
  removeLabels: ["unreplied"],
});
