Now in public beta · free

Give your agent an email address. In under two minutes.

Anyone can send an email — so your agent should have one. Signed identity, conversation threading, and a human-in-the-loop gate. No mail server. No public URL.

$ npm i -g @e2a/cli·$ pip install e2a·Apache 2.0

01 · How it works

Up and running in three steps.

No mail server to configure. No custom inbox to build.

STEP 01

e2a agents register my-agent

STEP 02

Connect your agent

CLI, Python or TypeScript SDK, or the Claude Code skill. Local agents use WebSocket, cloud agents use webhooks — same delivery contract.

pip install e2a

STEP 03

Receive, reply, stay in thread

Inbound mail arrives signed: sender identity, SPF/DKIM verdict, and a conversation_id that survives the email ↔ structured-data boundary.

on_message(msg)

02 · Quick start

A few lines of code.

Pick your interface. Everything else is already wired up.

~/my-agent

# install

npm install -g @e2a/cli

# register your agent

e2a agents register my-agent

# listen for inbound email, forward to your local server

e2a listen --agent my-agent@agents.e2a.dev --forward http://localhost:3000

03 · Human-in-the-loop

Approve before your agent hits send.

Flip one switch and outbound messages pause for your review instead of going straight out. You get a notification — click to see recipients, subject, and body on a secure confirmation page. Approve, edit, or reject.

Per-agent, opt-in, off by default. Configurable TTL with auto-approve or auto-reject on expiry. Reviewable from the dashboard, CLI, or one-click magic links in your inbox.

04 · Use cases

What you can build.

If it can receive email and take action, e2a can power it.

Support

Support and intake

Triage inbound requests, answer common questions, and hand off to humans without changing how customers reach you.

Admin

Scheduling and admin

Coordinate meetings, send reminders, and follow up where most people already live — their inbox.

Sales

Sales and follow-through

Qualify leads, reply to outreach, and keep conversations moving with a verified agent identity.

Auth

OTP and verification

Receive verification codes, confirmation emails, and magic links — then act on them automatically.

Voice

Voice agents

After a call ends, your voice agent sends a follow-up, receives a reply, and keeps the thread going.

Procurement

Coordinate with vendors, chase POs, and manage supplier threads with partners who still run on email.

Your agent's inbox is one sign-in away.

Free during beta. No credit card. Up and running in under two minutes.
