Send an email POST

The only irreversible action in this API: it leaves the system and reaches a third party. Requires the `write` scope AND `allowOutboundSend` enabled on the key: the scope alone is deliberately not enough. Always send an `Idempotency-Key`: a retry after a network timeout would otherwise deliver the message twice.

List signatures GET

Call this to turn a signature name into the id that `signature` takes on a send or a draft.
