Send email

Build a base64url-encoded RFC 2822 message and use users.messages.send.

IMPORTANT: If the Subject contains non-ASCII characters (Chinese, Japanese, etc.), you MUST encode it using RFC 2047 MIME encoded-word syntax: =?UTF-8?B?<base64>?=. Use echo -n 'subject text' | base64 -w 0 to get the base64, then wrap it as =?UTF-8?B?...?=. ASCII-only subjects can be used as-is.

Example (ASCII subject):

{"command": "echo -e 'From: me\\nTo: [e-mail]\\nSubject: Hello\\nContent-Type: text/plain; charset=utf-8\\n\\nHello Alice!' | base64 -w 0 | tr '+/' '-_' | tr -d '=' | xargs -I {} gws gmail users messages send --params '{\"userId\":\"me\"}' --json '{\"raw\":\"{}\"}'", "timeout": 30000}

Example (non-ASCII subject):

{"command": "SUBJ=$(echo -n '报告标题' | base64 -w 0) && echo -e \"From: me\\nTo: [e-mail]\\nSubject: =?UTF-8?B?${SUBJ}?=\\nContent-Type: text/plain; charset=utf-8\\n\\nHello!\" | base64 -w 0 | tr '+/' '-_' | tr -d '=' | xargs -I {} gws gmail users messages send --params '{\"userId\":\"me\"}' --json '{\"raw\":\"{}\"}'", "timeout": 30000}

{"command": "gws gmail users messages modify --params '{\"userId\":\"me\",\"id\":\"MESSAGE_ID\"}' --json '{\"removeLabelIds\":[\"INBOX\"]}'", "timeout": 30000}

Rules

• userId is always "me".
• List messages returns only IDs and threadIds. Use get with format: full to read content.
• Sending email requires base64url-encoded RFC 2822 format in the raw field.
• Use Gmail search syntax in the q parameter for filtering.
• For attachments: use users messages attachments get after reading the message to get attachment metadata.
