gog Gmail

Gmail Operations via gog CLI

Interact with Gmail using the gog CLI tool (gog gmail or aliases gog mail, gog email).

Prerequisites

Verify gog is available and authenticated before executing commands:

gog gmail labels list

If authentication fails, inform the user to run gog auth add <email> first.

Core Principles

• Always use --json when parsing output programmatically (e.g., extracting message IDs, threading). Use human-readable output when displaying results directly to the user.
• Use --dry-run before any send or destructive operation. Run the command with -n first, show the user what will happen, then execute after confirmation.
• Use --no-input to prevent interactive prompts from blocking execution.

Command Reference

Searching Email

Search threads using Gmail query syntax:

gog gmail search "<query>" --max=10

Common query patterns:

• from:[email protected] — from a specific sender
• to:[email protected] — to a specific recipient
• subject:meeting — subject contains "meeting"
• is:unread — unread messages
• is:starred — starred messages
• has:attachment — messages with attachments
• after:2026/01/01 before:2026/03/01 — date range
• label:important — by label
• "exact phrase" — exact phrase match
• Combine: is:unread from:[email protected] has:attachment

To search individual messages instead of threads:

gog gmail messages search "<query>" --max=10

Key flags:

• --max=N — max results (default: 10)
• --all — fetch all pages
• --page=<token> — pagination token
• --fail-empty — exit with code 3 if no results
• --timezone=<tz> — output timezone (IANA name)

Use --json to get structured output with message IDs.

Reading Messages

Get a specific message by ID:

gog gmail get <messageId>
gog gmail get <messageId> --format=metadata --headers=From,To,Subject,Date

Formats: full (default), metadata (headers only), raw (RFC 2822).

Reading Threads

Get an entire conversation thread:

gog gmail thread get <threadId>

List attachments in a thread:

gog gmail thread attachments <threadId>

Download a specific attachment:

gog gmail attachment <messageId> <attachmentId> --out=/tmp/

Sending Email

Always preview with --dry-run first:

gog gmail send --to="[email protected]" --subject="Subject" --body="Message body" --dry-run

After user confirms, execute without --dry-run:

gog gmail send --to="[email protected]" --subject="Subject" --body="Message body"

Key flags:

• --to, --cc, --bcc — recipients (comma-separated)
• --subject — subject line
• --body — plain text body
• --body-html — HTML body (optional, alongside or instead of --body)
• --body-file — read body from file (- for stdin)
• --attach=path — file attachment (repeatable)
• --reply-to-message-id=<id> — reply to a specific message
• --thread-id=<id> — reply within a thread
• --reply-all — auto-populate recipients from original (requires --reply-to-message-id or --thread-id)
• --quote — include quoted original message in reply

Replying to Email

To reply to an email, combine --reply-to-message-id (or --thread-id) with send:

# Preview first
gog gmail send --reply-to-message-id=<messageId> --body="Reply text" --reply-all --quote --dry-run
# Then execute
gog gmail send --reply-to-message-id=<messageId> --body="Reply text" --reply-all --quote

Draft Operations

gog gmail drafts list                          # List all drafts
gog gmail drafts get <draftId>                 # View draft details
gog gmail drafts create --to="..." --subject="..." --body="..."  # Create draft
gog gmail drafts update <draftId> --body="..."  # Update draft
gog gmail drafts send <draftId>                # Send a draft
gog gmail drafts delete <draftId>              # Delete a draft

Label Management

gog gmail labels list                          # List all labels
gog gmail labels get <labelIdOrName>           # Get label details with counts
gog gmail labels create <name>                 # Create a new label
gog gmail labels delete <labelIdOrName>        # Delete a label

Apply or remove labels on threads:

gog gmail labels modify <threadId> --add=INBOX --remove=UNREAD

Batch Operations

Modify labels on multiple messages:

gog gmail batch modify <messageId1> <messageId2> --add=STARRED

Permanently delete multiple messages (destructive — use --dry-run):

gog gmail batch delete <messageId1> <messageId2> --dry-run

Useful Utilities

Get Gmail web URL for a thread:

gog gmail url <threadId>

Workflow Patterns

Search-Read-Reply

A typical email workflow:

1. Search for the email: gog gmail search "from:alice subject:project" --json --no-input --max=5
2. Extract thread/message ID from JSON output
3. Read the thread: gog gmail thread get <threadId>
4. Reply: gog gmail send --reply-to-message-id=<messageId> --body="..." --reply-all --quote --dry-run
5. After user confirms, execute without --dry-run

Label-Based Triage

1. List labels: gog gmail labels list
2. Search unread: gog gmail search "is:unread" --max=20
3. Apply labels: gog gmail labels modify <threadId> --add=<label> --remove=UNREAD

Safety Rules

• Never send email without --dry-run preview and user confirmation.
• Never batch delete without --dry-run preview and user confirmation.
• When searching, default to --max=10 to avoid overwhelming output.
• When displaying email content, be mindful of sensitive information.
