Gmail Query Syntax

Gmail supports powerful search operators:

| Query | Description | |-------|-------------| | from:[email protected] | Emails from a specific sender | | to:[email protected] | Emails to a specific recipient | | subject:meeting | Emails with "meeting" in subject | | is:unread | Unread emails | | is:starred | Starred emails | | is:important | Important emails | | has:attachment | Emails with attachments | | after:2024/01/01 | Emails after a date | | before:2024/12/31 | Emails before a date | | newer_than:7d | Emails from last 7 days | | older_than:1m | Emails older than 1 month | | label:work | Emails with a specific label | | in:inbox | Emails in inbox | | in:sent | Sent emails | | in:trash | Trashed emails |

Combine with AND (space), OR, or - (NOT):

python scripts/gmail.py search "from:[email protected] is:unread newer_than:1d"
python scripts/gmail.py search "subject:urgent OR subject:important"
python scripts/gmail.py search "from:[email protected] -is:starred"
