agentmail

Give an agent its own email address. Send and receive email through the AgentMail API via the official agentmail CLI: create inboxes, send mail, read incoming messages and threads, reply / reply-all / forward, manage and schedule drafts, triage an inbox, keep a local address book of people and other agents, relay tagged work orders to another AI agent, and run the agent self-signup and OTP verification flow. Ships an opt-in hook that notices unread mail during a session. Triggers on mentions of AgentMail, agent email, inbox creation, sending or checking email for an agent, contacts or address lookup, inbox triage, and emailing another agent.

What it installs

Skills (5)

  • check-mail

    Check an AgentMail inbox and triage it — list unread or recent mail, read full message bodies rather than previews, and classify each one as actionable, needs-reply, FYI, or spam with a proposed next step. Also turns the periodic unread reminder on or off. Triggers on: check my mail, any new mail, w

  • contacts

    Address book for agent email — add, list, update, remove, and look up contacts (people and other agents) by name, alias, or address, so an AgentMail send goes to a verified address instead of a remembered one. Records how each email address was confirmed. Triggers on: what is X's email, who is X, ad

  • relay-work-order

    Hand work to another AI agent over AgentMail email, or act on a work order that arrived that way, using the agreed protocol: a [HANDOFF] / [ASK] / [FYI] / [DONE] subject tag and a Goal / Context / Needed / Refs body. Destructive or outward-facing actions never happen off an email alone. Triggers on:

  • replying

    Answer AgentMail messages in thread — reply to the sender, reply-all to everyone on the thread, or forward to someone new, with a reviewable draft for anything consequential. Counts recipients before a reply-all and never retries a failed send. Triggers on: reply to that email, answer this message,

  • using-agentmail

    Send and receive email for an AI agent via the AgentMail API and `agentmail` CLI — create inboxes, send, read messages and threads, reply/forward, manage drafts, run agent self-signup + OTP verification. Also fires when the agent is asked about its own email identity ('what is your email address?',
