What kind of messages deliver non-promotional information triggered in direct response to a transaction-related event?

Transactional messages are triggered by a user's action or a specific event related to their interaction with a business, such as order confirmations, shipping updates, password resets, or account notifications. They are non-promotional and provide essential information directly relevant to the transaction. Marketing messages and promotional messages, conversely, are designed to persuade recipients to make a purchase or engage with a brand for commercial purposes, rather than fulfilling an immediate informational need stemming from a transaction.
