- `list_mailboxes`: The mailboxes this key may use, what kind each is, and what the key may do.
- `list_folders`: The folders in a mailbox with unread and total counts.
- `list_messages`: The newest messages in a folder: sender, subject, date, a snippet, and whether each is unread.
- `search_messages`: Search a mailbox across folders by words and, where enabled, by meaning. Supports from:, to:, subject:, in:, has:attachment, kind:order, before: and after:.
- `get_message`: One message as text, with its attachments listed and any order, invoice, delivery or booking the sender declared as structured data. Messages carrying one-time codes are withheld unless the key may read codes.
- `mark_message`: Set or clear the read flag on a message.
- `move_message`: Move a message to another folder. Archive and Trash are folders; nothing is deleted outright.
- `send_message`: Send plain-text mail from a mailbox. If this key may only send with approval, the message is held and the result says waiting_for_approval; check send_status later. Never assume a held message was delivered.
- `send_status`: Whether a message held for approval is still waiting, was sent, or was rejected.
- `list_purchases`: Orders, invoices, deliveries and bookings that senders declared in schema.org markup, each linked to the message it came in.
