## What this connects

AgentMail provides AI agents with their own email inboxes, enabling them to send, receive, and act upon emails for communication with services, people, and other agents.

Vendor: https://agentmail.to

## Tools available

**5** tools available. First 5:

- `AGENT_MAIL_CREATE_INBOX` — Create Inbox — Create a new AgentMail inbox via API. Returns the inbox_id and email address for sending/receiving messages. Use when provisioning new inboxes for agents or workflows.
- `AGENT_MAIL_GET_MESSAGE` — Get Message — Retrieve the complete details of a specific email message from an AgentMail inbox. This action returns the full message content including sender, recipients, subject, body (both text and HTML), attachments, labels, and metadata. Use this to read individual messages after discovering them via LIST_MESSAGES or webhooks.
- `AGENT_MAIL_LIST_INBOXES` — List Inboxes — List all inboxes available to the authenticated AgentMail account. Use this to discover valid inbox_id values for message operations.
- `AGENT_MAIL_LIST_MESSAGES` — List Messages — List messages from an AgentMail inbox. Returns a `messages` array; each message uses `message_id` and `timestamp` fields (not `id`, `date`, or `items`).
- `AGENT_MAIL_SEND_EMAIL` — Send Email — Send an email using AgentMail API

## Auth

Auth schemes: `API_KEY`.

## How agents use Agent Mail

Inside a Definable workflow, Agent Mail is one of the tools the **Distributor specialist** can call. Example coordination patterns:

- **Researcher → Agent Mail** — the Researcher (GPT-5.5) pulls context from Agent Mail (records, threads, documents), synthesises findings, and briefs the rest of the team.
- **Writer → Distributor → Agent Mail** — the Writer (Claude Opus 4.7) drafts copy in brand voice, the Verifier passes it, then the Distributor writes the result into Agent Mail (create record, post message, draft email).
- **Designer / Engineer → Distributor → Agent Mail** — the Designer ships an asset or the Engineer ships a code change, the Distributor delivers it via Agent Mail (attach file, open PR comment, post status).

The Verifier checks every Agent Mail call. On rate limit, schema drift, or auth refresh it self-heals and retries — the workflow completes without manual intervention.
