Transactional e-mail refers to automated electronic messages that are sent to an individual in response to a specific action or transaction they have initiated. These emails are typically triggered by a user’s interaction with a website, app, or service, and are designed to provide important information or updates related to that transaction. Unlike promotional or marketing emails, transactional emails are focused on delivering relevant and timely information, such as order confirmations, shipping notifications, password resets, and account updates. They play a crucial role in facilitating smooth and efficient communication between businesses and their customers, ensuring transparency and building trust.
