# List emails

> List emails across your mailboxes, newest first. Results carry a `snippet` preview but never the message body; fetch a single email to read it. Filter by mailbox, campaign, conversation, lead, read state, direction, folder, date, or full-text search.

Requires one of the following scopes: `emails:read`, `emails:all`, `all:read`, `all:all`.

            The filters are applied first, then the newest survivor of each

            you the last email each contact sent you, even in conversations you
            have already replied to. An email that belongs to no conversation is
            a conversation of one and is always kept.
