Mailapp Send Email

Send emails through the macOS Mail app using AppleScript. Use when a task requires composing or sending email via Mail.app (including to/cc/bcc, subject, body, or attachments), or when the user asks for Mail app automation or osascript-based email sending. Use when this capability is needed.

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.

osascript /Users/ivancampos/.codex/skills/mailapp-send-email/scripts/send_mail.applescript \
  --to "test@test.com" \
  --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.
