Relationship to the macOS automation skill

• Use automating-mac-apps for permissions, shell, and UI scripting guidance.
• PyXA Installation: See automating-mac-apps skill (PyXA Installation section).

Core Framing

• Mail dictionary is AppleScript-first; discover in Script Editor.
• Objects are specifiers: read via method calls (message.subject()), modify via assignments (message.readStatus = true).
• ObjC bridge available for advanced filesystem operations.

Workflow (default)

1. Ensure Mail configured and automation permissions enabled.
2. Discover terms in Script Editor (Mail dictionary).
3. Prototype minimal AppleScript command.
4. Port to JXA with defensive checks.
5. Use batch reads for performance.
6. Use UI scripting for signature and UI-only actions.

Quick Start Examples

Read inbox (JXA):

const Mail = Application('Mail');
const message = Mail.inbox.messages[0];
console.log(message.subject());

Compose message (JXA):

const msg = Mail.OutgoingMessage({
  subject: "Status Update",
  content: "All systems go."
});
Mail.outgoingMessages.push(msg);
msg.visible = true;

PyXA alternative:

import PyXA
mail = PyXA.Mail()
inbox = mail.inboxes()[0]
message = inbox.messages()[0]
print(f"Subject: {message.subject()}")

Validation Checklist

• Automation permissions granted (System Settings > Privacy > Automation)
• Inbox access works: Mail.inbox.messages.length
• Message property reads return expected values
• Composition creates visible draft
• Batch operations complete without errors

When Not to Use

• For cross-platform email automation (use IMAP/SMTP libraries)
• For bulk email sending (use transactional email services like SendGrid)
• When processing untrusted email content (security risk)
• For non-macOS platforms
