osascript-email

Send email via Mail.app using AppleScript. No password or API key needed — Mail.app handles auth.

Prerequisites

• macOS with Mail.app installed
• At least one email account configured in Mail.app
• Verify the sender address matches a configured Mail.app account
• Authorization: This skill sends email silently from Mail.app. Only use with explicit user consent. Never use to send on behalf of a user without their knowledge.

Quick send (exec)

Use exec to run an inline osascript command. The script below is the canonical pattern — copy it exactly, then substitute values.

osascript << 'APPLESCRIPT'
tell application "Mail"
  set m to make new outgoing message with properties {subject:"YOUR SUBJECT", content:"YOUR BODY", visible:false}
  tell m
    make new to recipient with properties {address:"recipient@example.com"}
    make new to recipient with properties {address:"cc@example.com"}
  end tell
  send m
end tell
return "sent"
APPLESCRIPT

Escaping rules:

• Double quotes inside subject/content must be escaped: \"
• Backslashes must be doubled: \\
• Newlines inside content: use \n (AppleScript treats literal newlines in the string as content)

Python helper (for agent scripts)

Use when sending email from a Python cron script or agent workflow. Copy the function from scripts/send_email.py — do not rewrite it.

from scripts.send_email import send_email

send_email(
    subject="Daily Report — 2026-01-01",
    body="Here is the summary...",
    to="primary@example.com",
    cc="secondary@example.com",       # optional
    sender="your-mail-app-account@icloud.com"  # must match Mail.app account
)

See scripts/send_email.py for the full implementation.

Multi-recipient

Add additional make new to recipient lines inside the tell m block:

make new to recipient with properties {address:"a@example.com"}
make new to recipient with properties {address:"b@example.com"}

Troubleshooting

Limitations

• Plain text only (no HTML, no inline images)
• Attachments possible but require additional AppleScript — see references/attachments.md
• Rate: Mail.app will queue and send; not suitable for bulk sends (>10 emails)
• Sender must be a configured Mail.app account — cannot spoof arbitrary addresses
