Giving Your AI Agent Its Own Email Address

Most AI agents live inside a chat window. They can answer questions, write code, and call APIs — but they can’t talk to people outside that window. They have no way to reach someone over email, and no address where anyone can reach them.

That changes today. With AgentPatch’s email tools, any AI agent connected to the marketplace can claim a custom email address, send messages, and check an inbox for replies.

How it works

AgentPatch provides three email tools through the MCP protocol:

  1. Claim Address — your agent picks a handle and gets an address like [email protected]
  2. Send Email — send plain text or HTML emails to any recipient
  3. Check Inbox — poll the inbox for incoming messages and replies

That’s it. No SMTP configuration. No DNS records. No OAuth flows. Your agent calls a tool and it has email.

Claiming an address

The agent calls the claim-email-address tool with a handle. Handles are lowercase alphanumeric with hyphens, between 3 and 30 characters. Once claimed, the address is yours.

handle: "research-bot"
→ [email protected]

The address persists across sessions. Your agent claims it once, then uses it forever.

Sending an email

The send-email tool takes a recipient, subject, and body. Optional fields let you set a display name and reply-to address.

{
  "to": "[email protected]",
  "subject": "Weekly research summary",
  "body": "Here are the top findings from this week...",
  "from_name": "Research Bot"
}

HTML bodies are supported too, so agents can send formatted reports, tables, and styled content.

Checking the inbox

The check-inbox tool returns messages sent to your agent’s address. Each message includes the sender, subject, plain text body, and a timestamp.

This closes the loop. People can reply to your agent’s emails, and the agent can read those replies and act on them.

Why this matters

Email is still how most professional communication happens. Giving an agent an email address means it can:

  • Send reports to stakeholders who don’t use your chat tool
  • Receive instructions from people who prefer email
  • Participate in email threads alongside humans
  • Act as a point of contact for automated workflows

The agent stops being a tool you use and starts being a participant you collaborate with.

AgentPatch is an open marketplace where AI agents discover, purchase, and use tools at runtime. Browse tools or read the docs to get started.
