Your agent gets an inbox.
Create mailboxes programmatically. Each agent gets its own email address with full send, receive, read, and thread capabilities.
import { Transactional } from '@usetransactional/node';
const tx = new Transactional({
apiKey: process.env.TRANSACTIONAL_API_KEY,
});
// Create a mailbox for your agent
const mailbox = await tx.agentEmail.mailboxes.create({
name: 'research-agent',
domain: 'agentmail.usetransactional.com',
});
// → research-agent@agentmail.usetransactional.com
// Send an email
await tx.agentEmail.send({
from: mailbox.address,
to: 'user@example.com',
subject: 'Research Complete',
html: '<p>Here are your findings...</p>',
});
// Read the inbox
const messages = await tx.agentEmail.inbox.list({
mailbox: mailbox.id,
unread: true,
});
// Reply to a thread
await tx.agentEmail.reply({
messageId: messages[0].id,
html: '<p>Updated findings attached.</p>',
});Built for Agents
Email infrastructure designed specifically for programmatic access by AI agents.
99.9%
Deliverability
Same infrastructure as transactional email with DKIM, SPF, DMARC.
Full
Inbox API
List, search, read, label, archive — like Gmail but via API.
<2s
Inbound Latency
Incoming emails available via API in under 2 seconds.
Per-Agent
Isolation
Each agent has isolated mailbox, keys, and rate limits.
Email built for agents, not humans.
Traditional email APIs assume human senders. Agent Email is API-first from the ground up.
The old approach
- Gmail OAuth complexity
- Mailgun lacks inbox/read
- No per-agent isolation
- Manual threading logic
The modern approach
- API key auth, no OAuth
- Full inbox + deliverability
- One mailbox per agent
- Automatic thread tracking
Everything agents need for email.
Complete email infrastructure with agent-first design.
Instant Setup
Create a mailbox and start sending in under 60 seconds.
Per-Agent Auth
Each agent gets isolated API keys with rate limits and IP allowlists.
Simple SDK
Send, receive, search, and manage inbox with a few lines of code.
