# List your inbox, 100 at a time (read-only)
gws gmail users messages list --params '{"userId": "me", "labelIds": ["INBOX"], "maxResults": 100}'

# For each message id: sender, subject and Gmail's snippet (the first line or two)
gws gmail users messages get --params '{"userId": "me", "id": "MESSAGE_ID", "format": "metadata", "metadataHeaders": ["Subject", "From"]}'
