AgentMail CLI

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

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

A resource nested under another is a nested subcommand, e.g. inboxes messages, inboxes threads, pods inboxes, pods threads (CLI 1.x; the colon form inboxes:messages is rejected). Run agentmail <resource> --help to list what a resource supports.

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 "recipient@example.com" \
  --subject "Hello" \
  --text "Message body"

# HTML body instead of plain text
agentmail inboxes messages send --inbox-id <inbox_id> \
  --to "recipient@example.com" \
  --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 "someone@example.com"

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 "recipient@example.com" \
