🟢draft_email(to, subject, body, cc, bcc, ...)
Drafts one email the user sends themselves. Use when the user wants to email someone or needs an .eml file for Apple Mail, Outlook or Thunderbird. Only body is required. Leave to empty for a draft with no recipient. Returns a mailto: link that opens the email app with recipient, subject and body filled in, plus the full .eml draft text. If the link is over 2,000 characters, warning says so: give the user the .eml text instead. Nothing is sent or stored. Do not use for Instagram, LinkedIn, SMS or bulk email: Send Out cannot send those, so tell the user and offer an email draft instead.
