agentmail-cli

name	agentmail-cli
description	Operate AgentMail from a shell with the official CLI. Use when the user wants commands for listing or creating inboxes, reading or searching mail, sending or replying, managing drafts, or scripting JSON/YAML output; do not use for SDK code, MCP setup, or framework adapters.

AgentMail CLI

Install the CLI and provide the API key through the environment.

npm install -g agentmail-cli
export AGENTMAIL_API_KEY="am_..."

Subcommands for a resource nested under another use a colon, e.g. inboxes:messages, inboxes:threads, pods:inboxes, pods:threads.

Inboxes

agentmail inboxes list
agentmail inboxes get --inbox-id <inbox_id>
agentmail inboxes create --display-name "Support Agent" --username support
agentmail inboxes delete --inbox-id <inbox_id>

Confirm the exact inbox before running the destructive delete command.

Messages and threads

agentmail inboxes:messages list --inbox-id <inbox_id>
agentmail inboxes:messages get --inbox-id <inbox_id> --message-id <message_id>

agentmail inboxes:messages send --inbox-id <inbox_id> \
  --to "[e-mail]" \
  --subject "Hello" \
  --text "Message body"

# HTML body instead of plain text
agentmail inboxes:messages send --inbox-id <inbox_id> \
  --to "[e-mail]" \
  --subject "Hello" \
  --html "<h1>Hello</h1>"

agentmail inboxes:messages reply --inbox-id <inbox_id> \
  --message-id <message_id> \
  --text "Reply body"

agentmail inboxes:messages forward --inbox-id <inbox_id> \
  --message-id <message_id> \
  --to "[e-mail]"

agentmail inboxes:threads list --inbox-id <inbox_id>
agentmail inboxes:threads get --inbox-id <inbox_id> --thread-id <thread_id>

Use a message ID for replies. Fetch the full message before relying on body content.

Drafts

agentmail inboxes:drafts create --inbox-id <inbox_id> \
  --to "[e-mail]" \
  --subject "Pending approval" \
  --text "Draft body"

agentmail inboxes:drafts list --inbox-id <inbox_id>
agentmail inboxes:drafts get --inbox-id <inbox_id> --draft-id <draft_id>
agentmail inboxes:drafts send --inbox-id <inbox_id> --draft-id <draft_id>

Pods

Pods group inboxes together.

agentmail pods create --name "My Pod"
agentmail pods list

agentmail pods:inboxes create --pod-id <pod_id> --display-name "Pod Inbox"
agentmail pods:inboxes list --pod-id <pod_id>

agentmail pods:threads list --pod-id <pod_id>
agentmail pods:threads get --pod-id <pod_id> --thread-id <thread_id>
