version: "1.0.0" 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.

bash

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

bash

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

bash

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

bash

agentmail inboxes drafts create --inbox-id <inbox_id> \
  --to "recipient@example.com" \
  --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.

bash

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>

Webhooks

bash

agentmail webhooks create --url "https://example.com/webhook" --event-type message.received
agentmail webhooks list

Domains

bash

agentmail domains create --domain example.com
 
# Optional: route bounce/complaint notifications to your inboxes.
agentmail domains create --domain example.com --feedback-enabled
 
agentmail domains verify --domain-id <domain_id>
agentmail domains get-zone-file --domain-id <domain_id>
