EMAIL INFRASTRUCTURE FOR AI AGENTS
Build agents that work over email.
e2a gives every agent a real, authenticated inbox. Receive requests, take action, reply in-thread, and bring in a human when the action matters.
What e2a provides
An agent identity
A real address that belongs to the agent, not a human mailbox it happens to read.
A two-way channel
Receive authenticated mail and send replies that stay in the same conversation.
A safer action boundary
Hold outbound mail for human approval and pass sender evidence into the agent.
THE OPTIONS
Ways to give an AI agent its own email address.
The main options are a dedicated email gateway, connecting an existing Gmail or Outlook account, direct IMAP access, or forwarding mail into an AI integration. A dedicated gateway is the only option purpose-built to give the agent its own real address with sending, receiving, and threading built in — e2a is one such gateway.
| Option | How it works | Examples |
|---|---|---|
| Dedicated email gateway | The agent owns a real address and inbox with sending, receiving, and threading built in. | e2a, AgentMail |
| Connect an existing account | Programmatic access to a personal Gmail or Outlook mailbox through provider APIs. | Gmail API, Microsoft Graph |
| Direct IMAP access | Read and send through the mail server protocol directly; you manage auth and parsing. | IMAP client libraries |
| Forward into an AI integration | Point an existing address at an AI service that reads and replies for you. | Easy-Peasy, Carly |

Email API for AI agents: FAQ
What are the best ways to give an AI agent its own email address?+
The best way is a dedicated email gateway: the agent gets a real, authenticated inbox it can send from, receive into, and reply in-thread — e2a is one such gateway. The other main options are connecting an existing Gmail or Outlook account, direct IMAP access, and forwarding mail into an AI integration.
What is an email API for AI agents?+
An email API for AI agents gives an agent its own email identity and the programmatic ability to receive, send, and reply to messages. e2a adds authenticated inbound delivery, in-thread replies, multiple integration surfaces, and an optional human approval gate for outbound actions.
What is the difference between e2a and a transactional email API?+
A transactional email API primarily sends application mail. e2a gives an AI agent a two-way inbox of its own: it can receive requests, preserve conversation threads, reply from its identity, and hand sensitive actions to a human for approval.
What can I build with an AI agent email API?+
Developers use e2a to build support agents, AI receptionists, scheduling agents, ecommerce agents, sales and follow-up agents, recruiting agents, voice follow-up agents, and procurement agents that work through persistent email conversations.
How does e2a authenticate inbound email?+
e2a evaluates SPF, DKIM, and DMARC on inbound messages and delivers the authentication result as structured evidence. Webhook deliveries are signed so the receiving service can verify that the event came from e2a before invoking an agent.
