Mail.app Send Email

Overview

Use the bundled AppleScript to compose and optionally send Mail.app messages with structured inputs (to/cc/bcc/subject/body/attachments).

Quick Start

Run the AppleScript via osascript with --to, --subject, and --body. Pass comma-separated lists for multiple recipients or attachments.

bash
osascript /Users/ivancampos/.codex/skills/mailapp-send-email/scripts/send_mail.applescript \
  --to "[email protected]" \
  --subject "hello" \
  --body "testing"

Inputs

Use these flags. Only --to, --subject, and --body are required.

  • --to single email or comma-separated list
  • --cc optional comma-separated list
  • --bcc optional comma-separated list
  • --subject subject line
  • --body message body
  • --attach optional comma-separated POSIX file paths
  • --send optional true|false (default true, send immediately)

Behavior

  • Create a new outgoing message in Mail.app.
  • By default send immediately. If --send false, leave the draft visible for review.
  • If --attach is provided, add each file path as an attachment.

Troubleshooting

  • If Mail.app automation prompts appear, grant permissions in System Settings -> Privacy & Security -> Automation.
  • If attachments fail, ensure paths are absolute POSIX paths and the files exist.
