Gmail search syntax for GMAIL_FETCH_EMAILS:

is:starred                   # Starred emails  
is:important                 # Important emails
from:name@example.com        # From specific sender
to:name@example.com          # To specific recipient
subject:keyword              # Subject contains
has:attachment               # Has attachments
after:2026/01/01             # After date
before:2026/01/31            # Before date
label:INBOX                  # In specific label

Common Workflows

1. Daily Inbox Triage (Recommended 15-30 min/day)

Goal: Process inbox to zero efficiently

Steps:

# 1. Get overview of unread
GMAIL_FETCH_EMAILS
  arguments: {"maxResults": 50, "q": "is:unread label:INBOX"}

# 2. Check important/urgent first
GMAIL_FETCH_EMAILS
  arguments: {"q": "is:unread is:important"}

# 3. Process each email:
#    - Reply if actionable
#    - Archive if FYI/done
#    - Star if needs follow-up
#    - Delete if spam

# 4. Mark processed as read + archive
GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["msg_id_1", "msg_id_2"],
    "removeLabelIds": ["UNREAD", "INBOX"]
  }

The STAR Rule:

Span 2 minutes? → Do it now
Trash it? → Delete spam/irrelevant
Archive it? → Done, no action needed
Reply/Respond → Draft if complex

2. Achieving Inbox Zero

Process every email with a decision:

Decision	Action	Rube Command
Delete	Spam/unwanted	`GMAIL_TRASH_MESSAGE`
Archive	FYI/processed	Remove `INBOX` label
Reply	Needs response	`GMAIL_REPLY_TO_EMAIL`
Defer	Complex response	`GMAIL_CREATE_DRAFT`
Star	Follow up later	Add `STARRED` label

Batch archive processed emails:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2", "id3"],
    "removeLabelIds": ["INBOX"]
  }

3. Finding Specific Emails

By sender:

GMAIL_FETCH_EMAILS
  arguments: {"q": "from:name@example.com", "maxResults": 20}

By subject:

GMAIL_FETCH_EMAILS
  arguments: {"q": "subject:invoice", "maxResults": 20}

Recent unread with attachments:

GMAIL_FETCH_EMAILS
  arguments: {"q": "is:unread has:attachment newer_than:7d"}

Full thread context:

GMAIL_GET_THREAD
  arguments: {"threadId": "thread_id_here"}

4. Sending Emails

New email:

GMAIL_SEND_EMAIL
  arguments: {
    "to": "recipient@example.com",
    "subject": "Subject line",
    "body": "Email body text",
    "cc": "cc@example.com"  # optional
  }

Reply to thread:

GMAIL_REPLY_TO_EMAIL
  arguments: {
    "threadId": "thread_id",
    "body": "Reply text here"
  }

Save draft for later:

GMAIL_CREATE_DRAFT
  arguments: {
    "to": "recipient@example.com",
    "subject": "Draft subject",
    "body": "Work in progress..."
  }

5. Bulk Cleanup

Mark multiple as read:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2", "id3"],
    "removeLabelIds": ["UNREAD"]
  }

Archive multiple:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2", "id3"],
    "removeLabelIds": ["INBOX"]
  }

Star for follow-up:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2"],
    "addLabelIds": ["STARRED"]
  }

6. Label Organization

List all labels:

GMAIL_LIST_LABELS
  arguments: {}

Create project label:

GMAIL_CREATE_LABEL
  arguments: {"name": "Projects/ClientName"}

Apply label to emails:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2"],
    "addLabelIds": ["Label_ID_Here"]
  }

Best Practices

Productivity

Process in batches: Dedicated time blocks, not continuous checking
2-minute rule: If reply takes <2 min, do it now
Touch once: Make a decision on each email when you read it
Unsubscribe aggressively: Reduce incoming noise
Use filters: Auto-label/archive predictable emails

Safety

Always confirm before bulk deletes
Use maxResults to limit scope
Archive instead of delete when uncertain
Check trash before permanent deletion

Organization

Keep labels simple (max 2 levels deep)
Search is often better than complex folders
Star for follow-up, archive everything else
Weekly review of starred items

Common Scenarios

"Check my inbox"

# Get unread count and recent emails
GMAIL_FETCH_EMAILS
  arguments: {"q": "is:unread label:INBOX", "maxResults": 20}

"Find emails from [person]"

GMAIL_FETCH_EMAILS
  arguments: {"q": "from:person@email.com", "maxResults": 20}

"Send email to [person] about [topic]"

GMAIL_SEND_EMAIL
  arguments: {
    "to": "person@email.com",
    "subject": "Topic",
    "body": "Message content"
  }

"Archive all newsletters"

# First find them
GMAIL_FETCH_EMAILS
  arguments: {"q": "from:newsletter OR from:noreply label:INBOX", "maxResults": 50}

# Then archive batch
GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2", ...],
    "removeLabelIds": ["INBOX"]
  }

"Mark everything as read"

GMAIL_FETCH_EMAILS
  arguments: {"q": "is:unread label:INBOX", "maxResults": 100}

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": [...all ids...],
    "removeLabelIds": ["UNREAD"]
  }

Integration Notes
