Table 1: Search Operators
Search is Gmail's quiet superpower, and operators are how you wield it like a query language instead of a guessing game. Stack from:, has:attachment, date ranges, and size filters to pinpoint one message among tens of thousands — and once you internalize a handful of these, the urge to file everything into folders mostly disappears.
| Operator | Example | Description | |
|---|---|---|---|
from:alice@company.com | Finds emails sent by a specific person — use exact addresses or partial domains like from:@company.com. | ||
to:bob | Locates emails sent to a specific recipient — works with full addresses or domain patterns. | ||
subject:invoice | Searches only the subject line — combine with other operators for precise filtering. | ||
has:attachment from:hr | Finds all emails containing any attachment — pair with sender or date filters to narrow results. | ||
filename:pdf | Searches for attachments matching a specific file type or name — e.g., filename:xlsx or filename:report.docx. | ||
is:unread from:boss | Shows only unread messages — combine with sender or label operators to focus on specific items. | ||
is:read label:work | Shows only read messages — useful to filter already-processed email within a label. | ||
is:starred has:attachment | Displays starred (flagged) emails — typically marked manually for follow-up or reference. | ||
is:important | Shows emails marked as important by Gmail's algorithm or manual markers. | ||
is:snoozed | Finds temporarily hidden emails — surfaces all messages that have been snoozed for later. | ||
is:muted from:newsletter | Finds muted conversations — useful to review threads you silenced that are now bypassing inbox. | ||
after:2026/01/01 | Returns emails received after a specific date — use YYYY/MM/DD format. | ||
before:2026/06/01 | Returns emails received before a specific date — combine with after: for exact date ranges. | ||
newer_than:7d | Finds emails newer than a relative time period — use d (days), m (months), or y (years). | ||
older_than:2m | • Finds emails older than a relative time period — same units: d, m, y• no weeks unit. | ||
label:work-project | Filters emails assigned to a specific label — Gmail's alternative to folders. | ||
in:inbox is:unreadin:spamin:snoozedin:chats | Searches within a specific location — also in:trash, in:archive, in:sent, in:drafts, in:anywhere (all mail including spam/trash). | ||
category:promotionscategory:purchases | Finds emails in a specific inbox category — options: primary, social, promotions, updates, forums, purchases, reservations. | ||
has:drive | Shows emails containing Google Drive links — useful for finding shared documents. | ||
has:documenthas:spreadsheet | Finds emails with specific Google Workspace file types — targets Docs, Sheets, or Slides attachments individually. | ||
has:youtube | Finds emails with YouTube video links — filters newsletters or messages referencing video content. | ||
has:nouserlabels | Filters to emails with ( has:userlabels) or without (has:nouserlabels) custom labels applied — note: only message-level, not conversation-level. | ||
cc:manager | Finds emails where someone was copied (CC'd). | ||
bcc:me | • Finds emails where you were blind-copied — limited • you can't look up who others BCC'd. | ||
larger:10M | Returns emails larger than a specified size — M for megabytes, K for kilobytes. | ||
smaller:5M | Returns emails smaller than a specified size — useful to exclude large attachments from search results. | ||
size:5000000 | • Finds emails matching a byte size — 5,000,000 bytes ≈ 5MB • use for precise storage cleanup queries. | ||
from:alice OR from:bob | • Matches either condition — must be uppercase • use for multiple senders or subject variations. | ||
{from:alice from:bob} | • Alternative OR syntax — same as OR but shorter• e.g., {from:alice from:bob} equals from:alice OR from:bob. | ||
subject:(invoice receipt) | Groups multiple terms — subject:(invoice receipt) finds emails with either word in the subject. | ||
from:john AND has:attachment | Explicit AND — default behavior between terms, but explicit AND makes complex queries clearer. | ||
NOT from:noreply | • Excludes all matching results — uppercase NOT • equivalent to the - minus operator. | ||
from:support -subject:spam | Excludes terms — the minus sign negates any operator or keyword that follows. | ||
+invoice | • Forces exact word match — prevents Gmail from matching stemmed variants • useful for precise single-term searches. | ||
"urgent meeting" | Searches for an exact phrase — words must appear together in that specific order. | ||
proposal AROUND 5 budget | Finds emails where two terms appear within N words of each other — context-specific searches. | ||
deliveredto:me | Finds emails actually delivered to a specific address — useful when using multiple aliases or plus-addressed variants. | ||

Rfc822msgid:abc123@mail.gmail.com | • Searches by unique Message-ID header — most technical operator • useful for API-driven workflows. |
