For example, if you make an account on a website or buy something online, you will receive transactional emails for this action.

Transactional emails can be used in many ways. You can use them to show people when their order has been sent or received. You can also use them to let them know if their tracking number is working and where they are on the map.

Invoices and receipts can also be sent by email, as well as password reset emails and welcome emails for new members of your site or company.

These emails are not only marketing emails. They also help customers. You can use them to send customers marketing messages, or you can use them like transactional emails, like when people start an online store.
